Experts’ Interpretation of the Technical Guide for Derivation of Marine Biological Water Quality Standards (Trial)

  In order to protect the marine environment and promote the work of marine environmental standards, the Ministry of Ecology and Environment issued the Technical Guide for Derivation of Marine Biological Water Quality Standards (Trial) (HJ1260—2022) on July 18, 2022 (hereinafter referred to as the Guide). This is the first standard to guide and standardize the derivation of marine environmental standards in China, and relevant experts have answered relevant questions.
  Q: What is the significance of the publication of the Guide for China’s marine environmental protection?
  Researcher Yao Ziwei of National Marine Environmental Monitoring Center: Marine environmental benchmark is an important part of modern ecological environment governance system, and it is the basis and scientific basis for formulating China’s marine ecological environment quality standards, which can provide important support for China’s marine ecological environment risk assessment and emergency response.
  The current Standard for Seawater Quality (GB3097—1997) has played an important role in the prevention and control of marine pollution in China, but when the standard was first formulated, it was based on one or more foreign seawater quality standards (marine life, senses, health, etc.). As for marine biological water quality standards, there are great differences between different countries and even the same country in different periods due to the differences in derivation methods and concerned species. When conditions permit, countries should carry out relevant benchmark research according to their own marine ecological environment characteristics.
  The publication of the Guide is of great significance for strengthening the research of marine environmental standards in China, accelerating the transformation and application of research results, and improving the level of marine ecological environmental protection.
  Q: Since the 1980s, some developed countries and international organizations have successively issued water quality standards for marine organisms. In contrast, what are the unique features of the Guide in terms of methods and technical requirements?
  Researcher Wang Ying, National Marine Environmental Monitoring Center: Since 1980s, the environmental management departments of the United States, the European Union, the Netherlands, Australia/New Zealand and Canada and other countries and international organizations have successively issued technical guidelines for deriving water quality standards for protecting aquatic organisms (freshwater organisms and marine organisms) and water quality standards for protecting marine organisms according to their environmental management needs and water pollution status. In the process of compiling the Guide, domestic and foreign scientific research achievements were fully absorbed and used for reference.
  Methodologically, it is stipulated that the species sensitivity distribution method is used to derive the water quality standards of marine organisms, which is the mainstream method to derive the water quality standards of freshwater and marine organisms in the world at present, and it is also the method stipulated in the Technical Guide for Deriving Water Quality Standards of Freshwater Organisms (HJ831—2022).
  In terms of technical requirements, the characteristics and working basis of China’s marine ecosystem are fully considered: first, the toxicity data of marine species in China are required to be used to derive the water quality standards of marine organisms; Secondly, according to the species distribution of marine ecosystems in China, the minimum toxicity data requirements of "5 families and 8 species" based on the characteristics of marine biota in China are put forward; Thirdly, the calculation method of acute value/chronic value of the same effect is proposed, which solves the problem that different types of toxic effects have different weights and achieves the purpose of better protecting marine species in China. At present, only the European Union has put forward this technical requirement internationally.
  Q: How to consider the minimum toxicity data requirements of "8 species in 5 families" based on the characteristics of marine biota in China?
  Yan Zhenguang, researcher of china environmental science Research Institute: According to statistics, there are more than 3,000 species of microalgae and macroalgae in China, accounting for 11% of the total marine species in China; Arthropoda, Chordata, Annelida, Mollusca, Echinoderm and Rotifera are the main animal groups in China’s sea areas, with more than 17,000 species, accounting for 59% of the total marine species in China. The number of marine species in the above key groups of marine life in China accounts for more than 70% of the total marine species in China.
  In order to make the derivation of marine biological water quality benchmark reflect the characteristics of marine ecosystem in China, it is a basic principle to determine the minimum toxicity data requirements for the derivation of the benchmark. The tested species in seawater should cover the key groups of marine organisms in China, which is embodied in the following aspects: 1 family of microalgae or macroalgae, 2 families of crustaceans in Arthropoda and 1 family of bony fishes in Chordata; Other phylum, such as annelids, molluscs, echinoderms, rotifers, etc., or an unused family among crustaceans and teleost fishes.
  The minimum toxicity data requirements of 8 species are mainly considered from the following two aspects: from the point of view of mathematical statistics, the more species, the better the model effect; From the point of view of the robustness of species sensitivity distribution model and the reliability of reference value, if the toxicity data covers key biological groups, then the uncertainty of reference value based on more than 8 species is within the acceptable range. There are eight criteria for evaluating the number of species as "good" in the minimum toxicity data requirements of the Australian/New Zealand Technical Guidelines for Derivation of Water Quality Standards.
  At the same time, from the perspective of protecting marine biodiversity and marine ecology, it is clear that alien invasive species should not be used as a benchmark to deduce the tested species, such as marine microalgae that produce microcystins and Spartina alterniflora that compete with native species for nutrition.
  Q: We have noticed that there are great differences in the exposure time of different kinds of marine life in the Guide. How do you consider it?
  Professor Tan Qiaoguo of Xiamen University: Based on the standard testing methods of marine ecotoxicology at home and abroad, in order to protect marine species in China more pertinently, on the basis of analyzing the life history and reproductive characteristics of different types of marine species, the Guide puts forward the differential exposure time for 7 categories and 43 families of marine organisms such as algae, rotifers, annelids, molluscs, arthropods, echinoderms and chordates. According to the acute toxicity test, the generation cycle of Brachionus plicatilis is only about 2 days, and it is recommended that its exposure time should not be longer than 48 hours. For most arthropods and fish, the generation cycle is long, and the exposure time is recommended to be no more than 96 hours. According to the chronic toxicity test, the generation cycle of cladocera such as Daphnia mongolica is 5-7 days, and the exposure time is recommended to be no less than 5 days. However, the generation cycle of fish such as medaka can reach 3-4 months, and it is recommended that its exposure time should be no less than 21 days.
  Q: As the vice chairman of the National Expert Committee on Environmental Standards, I would like you to talk about what work needs to be promoted in the field of marine environmental standards in China during the 14 th Five-Year Plan period.
  Researcher Wang Juying, National Marine Environmental Monitoring Center: Marine environmental standards mainly include marine biological water quality standards and sediment quality standards for protecting marine ecosystems, nutrient standards for preventing water eutrophication, and people’s health standards for consuming seafood and marine recreational water.
  China’s marine environmental benchmark research began in 1980s, and made some progress. For example, related research provided direct technical support for the formulation of Marine Sediment Quality (GB18668—2002); The national "863" special project "Research on Key Technologies for Determining the Threshold of Marine Environmental Effects of Typical Organic Pollutants from Land-based Sewage Discharges into the Sea" and the marine public welfare scientific research special project "Research and Formulation of Offshore Seawater Quality Standards/Standards" won the first prize and the second prize of the Marine Engineering Science and Technology Award respectively.
  China’s sea area spans temperate zone, subtropical zone and tropical zone, and the marine ecosystem is diverse. From the perspective of protecting China’s marine ecosystem, during the Tenth Five-Year Plan period, based on protecting the integrity of China’s marine ecosystem, we should speed up the research and construction of China’s seawater quality benchmark system, develop the target pollutant marine biological water quality benchmark that has an important impact on China’s marine ecological environment quality, carry out the ecological risk threshold research of new pollutants such as endocrine disruptors, and develop the nutrient water quality benchmark of key sea areas such as Bohai Sea and South China Sea based on classification and zoning.
  Experts in the field of marine environmental benchmark research in China are distributed in different institutions. In order to ensure the smooth progress of the marine environmental benchmark work in the 14th Five-Year Plan, we should give full play to the role of the National Environmental Benchmark Expert Committee as a think tank platform, and the superior research teams in the United Nations should work together to organize joint research. Through cooperation in a wider space and at a higher level, we will contribute wisdom and strength to the marine environmental benchmark work in China, better serve the marine ecological environmental protection in China, and meet the urgent need to speed up the modernization of the ecological civilization governance system and governance capacity.
 

Does Guangdong No.1 Middle School charge 100 yuan/year per student for installing "face recognition system"? Bulletin of education bureau

  CCTV News:According to "Meijiang Education" WeChat WeChat official account news, on September 13th, the "face recognition system" of Meijiang Union Middle School in Meizhou City attracted attention from all walks of life, and the Education Bureau set up an investigation team to conduct an in-depth investigation. After investigation, the "face recognition system" is provided with paid services by related companies. The company’s leaflets are unclear and the school’s related communication work is weak, which has caused some parents to misunderstand. After investigation, students in this school can enter and leave the campus and dormitory normally regardless of whether they pay for the service or not, and there is no such thing as being unable to enter and leave. The relevant information is as follows:

  I. Basic information

  According to the survey, United Middle School is intended to strengthen campus safety management, and entrusts a third party to develop a "smart campus" platform. The cost of SMS notification and online related services is 100 yuan per student/year, which is a voluntary service item. Those who do not buy it will not affect their access to the school. At present, about 40% of parents of students voluntarily purchase.

  In addition, "A Letter to Parents" was drafted and printed by a third-party company, and sent to parents of students by the school. There are some problems in this letter, such as unclear content, especially whether it is possible to choose to buy services by yourself and whether it will affect access to campus without purchasing services, which has caused misunderstandings and added troubles to some parents.

  Second, the disposal situation

  In response to this incident, the Education Bureau convened relevant personnel to listen to opinions in depth and make the following treatments:One isOn the basis of full communication and respect for parents’ wishes, the joint middle school is ordered to assist the third-party company to do a full refund.The second isStrengthen the investigation and rectification of joint middle schools.The third isStrengthen the management of student safety and school safety in the whole region, strengthen research, and actively explore new mechanisms for campus safety management.

According to the survey, the average monthly living expenses of college students are 1212 yuan, which is more than 30% and not enough.

  BEIJING, Beijing, Feb. 15 (Reporter Kan Feng) It is another school season, and the "school-starting economy" of college students in China is once again hot. In recent years, online consumption, campus express delivery, campus loan and other college students’ consumption phenomena and behaviors have been continuously concerned by the society. So, what is the average consumption level and financial management means of college students? Recently, MyCOS Research Institute released a survey report on the consumption behavior of college students in China.

  How much can college students spend every month?

  — — The average monthly consumption is 1212 yuan, boys love socializing and girls love food.

  The survey, named "College Students’ Views on Consumption and Financial Management", was completed by means of online survey. The survey target was only college students, and a total of 1,289 valid answers were collected from college students in 2016.

  The survey shows that the average monthly expenditure of college students is 1212 yuan (excluding tuition and round-trip transportation between home and school). Family is the main source of students’ living expenses. 94% of students’ living expenses are provided by their parents or relatives, followed by part-time jobs.

  Where do college students spend their living expenses? According to this survey, the main consumption chosen by the surveyed boys is social and entertainment, other foods besides basic meals and image consumption, and the main consumption chosen by the surveyed boys is other foods besides basic meals, image consumption and social and entertainment consumption.

  The proportion of boys spending money on communication/Internet surfing fees (31%) and digital electronic products (16%) is 7 and 11 percentage points higher than that of girls, while the proportion of boys spending money on image consumption (38%) is 24 percentage points lower than that of girls.

  What do college students mainly look at when shopping?

  — — Shopping mainly depends on price and quality.

  It is found that the most important factor for students to consider in shopping is "price", and the second and third places are "quality" and "personal preference".

  According to the analysis of the report, as a college student class who has not formally entered the society, the source of living expenses is limited, and students pay more attention to price and quality than the brand, grade and advertising of goods when shopping, which shows that most students can spend rationally.

  With the living expenses in hand, will college students give up their money to "Qian Shengqian"? According to the survey, 57% students have managed their finances in different forms. Among the college students surveyed, 42% chose products such as Yu ‘ebao, Zhaocaibao and Licaitong, 24% chose traditional bank time deposits, and only 3% and 2% bought stocks and invested in P2P online loans. Most students choose a low-risk, robust financial management method.

  Is the living expenses of college students enough?

  — — Over 30% of the respondents sigh beyond their means.

  The survey results show that among the students surveyed, 41% of college students’ living expenses can meet their daily needs and have a balance. More than 30% of college students have made ends meet. According to the survey, 24% of the students’ living expenses are insufficient occasionally, and 8% are often insufficient.

  According to the analysis of the report, students’ living expenses are not enough. On the one hand, it may be due to factors such as the economic situation of individual families, and on the other hand, it may be due to students’ lack of planning for the use of living expenses.

  The survey shows that 40% of college students will not plan and arrange the use of living expenses. When the living expenses can’t meet the expenses, 43% of college students choose to give up consumption, while others will choose to ask their parents for help (40%), spend first and then pay (20%) and borrow money from friends (15%) to meet their consumption needs.

  The survey also showed that 39% of the students surveyed reported that someone around them had used campus loans. The report suggests that colleges and universities should pay more attention to students’ lives, guide students with financial difficulties to seek help and give them help, strengthen risk prevention education, and guide college students to spend rationally and plan their consumption.

Special issue commemorating the 80th anniversary of the completion of the Auditorium (5): the whole story of the construction of the Auditorium

From 1931 to 1934, Henan University spent three years and more than 210,000 yuan to build a palace-style auditorium.

In the process of construction, builders not only fully consider its safety and firmness, but also take into account its applicability and beauty. Members of the Architectural Committee of the Auditorium and accountants are all "unpaid". With hard work and selfless dedication, they left a permanent public building and an eternal spiritual wealth.


Early Henan University Auditorium

In 1912, on the former site of Henan Gongyuan, Henan Preparatory School for Studying in Europe and America was established. At the beginning, most of the school buildings used in the school were old houses in Gongyuan. In 1919, when Li Jingzhai was the principal, the school built Building 6. The building has a large area, so a lecture hall, the so-called auditorium, can accommodate three or four hundred people. Any assembly will be held here.


Building 6 has long been used as a lecture hall.


In March 1923, the pre-school was renamed Zhongzhou University, "the site of the headquarters is near Caomen in the south, the iron tower in the north, the city wall in the east and the Huiji River in the west." With the support of President Zhang Honglie, Li Jingzhai, director of school affairs, made an overall plan for the campus. From pre-school to university, the number of students has gradually increased, and although the lecture hall is crowded, it can barely be used. In August 1925, Li Dazhao gave a speech here entitled "The History of British Imperialism’s Invasion of China".


Zhongzhou University Planning Map

In 1927, Zhongzhou University was renamed as Henan Sun Yat-sen University after it merged with Henan Public Law School and Henan Provincial Agricultural College. As an auditorium, the lecture hall is still an important place for teachers and students to gather. In the winter of 1929, Fu Sinian gave a lecture in the lecture hall, talking about the development of archaeology and the excavation of Yin ruins. However, the number of students has increased to more than 900, and the lecture hall in Building 6 can no longer accommodate them.

It is extremely necessary to build an auditorium for teachers and students to gather, but it is difficult to raise funds for the construction.

As early as August 1922, under the impetus of Feng Yuxiang and Governor Zhang Fengtai, Henan Province formed a system of using deed tax as education funds and using it independently, and set up a special agency to distribute the education funds in the province. However, wars are frequent, the provincial fiscal revenue is uncertain, and the school allocation quota is difficult to guarantee. For example, in 1927, the fabricated budget was 300,000 yuan, and the school actually received 129,700 yuan; In 1928, the fabricated budget was 255,000 yuan, and the actual income was 227,000 yuan.

It is not easy to maintain school expenses, let alone build an auditorium. The school applied to the provincial government for funds to build the auditorium, but failed to do so. In desperation, the school built a shed as an auditorium and meeting place, which was not only unsightly in appearance, but also could not be used often in winter and summer because of the weather.

The school magazine of Henan University published on September 21st, 1933.


In 1930, the Central Plains War broke out. After defeating Feng Yuxiang, Chiang Kai-shek appointed his lineal Liu Zhi as the chairman of Henan Province. In September, Henan Sun Yat-sen University was renamed as the provincial Henan University. When President Zhang Zhonglu announced the five-year development plan to teachers and students, he was still in the school shed. Soon, Zhang Zhonglu announced his resignation. Zhao Xinwu acted as the principal for only two months, and Li Jingzhai, the provincial director of education, served as the principal for only four months. Principals change frequently, and their tenure is not long, so they have no time to take care of the construction of the auditorium.

Time and cost of building the auditorium

In May 1931, the provincial government appointed Xu Xinwu as the principal, and the construction of the auditorium ushered in a turning point.


President Xu Xinwu

Xu Xinwu studied in the United States in his early years and obtained a master’s degree in hydraulic engineering. After taking office, together with Li Jingzhai, he made adjustments and supplements to the campus planning of Heda University, and put forward suggestions for building the auditorium. At the same time, under the planning of President Xu Xinwu and Dean of Science College Zhao Xinwu, the school added a department of civil engineering, which was approved by the provincial government in June.

At that time, the Department of Civil Engineering was affiliated to the Faculty of Science, with Qu Wenlin as the dean. Qu Wenlin graduated from the Department of Civil Engineering of National Beiyang University (now Tianjin University) in 1921, was appointed as a teacher of Henan Institute of Surveying and Mapping of Water Conservancy Engineering, and took a part-time course in the School of Science of Henan University. The establishment of the Department of Civil Engineering not only expanded the disciplines and specialties of the school, but also provided technical support and talent guarantee for the building auditorium.

The construction of the auditorium was supported by teachers and students, and also by the provincial government. Although Liu Zhi was born in the military, he attached great importance to the revitalization of education during his administration in Henan, especially supported the construction of the auditorium. Later, in My Memories, he wrote: "To raise funds, build the auditorium of Henan University, expand and repair the school buildings of primary and secondary schools, and build the magnificent North China Stadium, in order to seek the initial measures for the development of education in Henan and arouse the joint efforts of local people."

In order to ensure the smooth progress of the project, the school hired Zhang Boying (namely zhangfang, then director of the provincial construction department), Li Jingzhai (then director of the provincial education department), Du Xiu monk (namely Joe Doo, then director of the education fund and production management department) and Qu Wenlin to form the Auditorium Construction Committee, among which Li Jingzhai, Du Xiu monk and Qu Wenlin served as the standing Committee members, who were responsible for design, economy and engineering. At the same time, Yan Shaozhang was hired to be responsible for drawing and project management. Yan Shaozhang participated in the topographic survey of North China Stadium, and was then an engineering professor at Henan University. (See "General Report of the 16th North China Games" published by Shanghai Dadong Bookstore in 1932, p. 101.) As for the positions such as accounting and general affairs, some school staff are concurrently employed.


Profile of auditorium

After intense and detailed planning, on November 20, 1931, the auditorium broke ground. On April 10, 1932, the school held a groundbreaking ceremony. The original construction period was one and a half years, but the project lasted until the winter of 1934. Due to weather changes, uneven materials and other reasons, the project has been shut down for 11 months, so the actual construction period is two years. In more than 750 days, the members and part-time staff of the Construction Committee were "not given jobs", which not only ensured the construction progress and project quality, but also saved a lot of expenses.

Before construction, the construction cost budget is about 140,000 yuan, and the equipment cost budget is about 30,000 yuan. With the consent of Liu Zhi, the Finance Department allocated 150,000 yuan for construction and 24,296 yuan for equipment. In addition, Zhongyuan Company donated 10,000 yuan. These payments, together with the interest generated one after another, total 185,143.18 yuan.

The expenditure on the construction of the auditorium consists of two parts: construction cost and equipment cost. The construction cost is more than 190,000 yuan, and it costs 145,998.817 yuan to buy wood, bricks, limestone, steel and miscellaneous parts. The total number of employees is 73,520, including 21,920 carpenters, 22,600 masons, 25,500 coolies and 3,490 handymen, with a total cost of 45,250.573 yuan. The expenses including steel chairs, electric lights, heating and other materials are called equipment expenses. When the auditorium was completed, only steel chairs were installed, and other equipment was not added, including 12,894.8 yuan for steel chairs, 5,827.8 yuan for transportation and 109.22 yuan for travel remittance. After adding up the construction cost and equipment cost, the actual expenditure reached 210,081.21 yuan.

Qu Wenlin made a detailed analysis of the construction time and expenses in the report. In his view, the reinforcement of foundation engineering, the purchase of steel frames from Britain, the change from wooden floors to reinforced concrete floors, the reinforcement of walls with steel bars and concrete, and the extension of construction period are the main reasons for exceeding the original budget.

The auditorium is sturdy and applicable, beautiful and cheap.

The engineering design of the auditorium is based on the safest standard. In order to ensure the safety of buildings, all materials used are assumed to have the largest external force and the smallest resistance. Although the cost of materials has increased, as a permanent public building, the safety and firmness of the auditorium have been greatly improved. For example, when building the foundation, the designer thought that the terrain of the auditorium was similar to that of Building No.7, but when he dug six feet, he found quicksand and serious water seepage. Designers and constructors use concrete as the lower foundation, and then arrange bricks closely, add mortar, and the foundation brick soil is made of lime, and the size is relaxed, and the load per square foot is calculated according to the worst foundation to ensure safety.

For another example, the auditorium was originally planned to use wooden floors, but for the sake of fire safety, all of them were replaced with steel bars and concrete. The south wall of the venue cannot be thickened due to the bearing capacity of the foundation. In order to ensure the safety, a reinforced concrete beam is added, extending from the east end to the west end and along the east wall to the north, with a total length of 160 feet to support the floor pressure, and 8 reinforced concrete columns are added to support the steel beam.

The interior window area of the auditorium accounts for one-fifth of the venue area, so the light is sufficient. The air capacity in the venue is 400,000 cubic feet, with an average of 160 cubic feet per person. The air is very smooth. In addition, the echo in the auditorium is very small, so you can hear it clearly at the end. Upstairs and downstairs, more than 2600 people can sit in the middle space. The podium, 60 feet wide and 40 feet deep, can hold meetings and plays, and can accommodate more than 200 people. In addition, there are 8 rooms upstairs and downstairs, which can be used as lounge, office, storage room and classroom, each holding 60 people. There are walkways around the venue, upstairs and downstairs for easy access.

Overlooking the auditorium

As the main building of the school at that time, the exterior of the auditorium was in the form of palace architecture, with upper plates in the corners, covered tiles and painted colors similar to those of the palace, while the interior was in the form of modern architectural techniques, with a view to being applicable. From all angles, the auditorium is magnificent and magnificent. Considering the construction cost, the auditorium can be regarded as inexpensive. Qu Wenlin said: "The cost of the Auditorium of Nanjing Central University and the Auditorium of Tsinghua University is nearly 200,000. Although the design of materials and materials are different, our auditoriums are quite unique in terms of beautiful area and solid capacity."

Pork defense war: many places have introduced policies to increase support for leading enterprises to land key projects

  On September 3, 2019, the price tag of cheap and assured pork was posted in the market of Nanning and ma village. Vision china map "Now the government is vigorously encouraging pig raising. Yesterday (September 5), the deputy county magistrate convened a meeting of farmers’ representatives, conveying the general meaning that the government supports farming, and if there are any problems, the government will come forward to solve them, and interest-free loans may be introduced later. The government will also do the work in environmental protection. " On September 6th, Liu Jian (a pseudonym), a pig farmer in xiushui county, Jiujiang City, Jiangxi Province, told The Paper.

  Including this mountainous county in northwest Jiangxi, promoting pig production and ensuring market supply is being actively promoted as an important livelihood project throughout the country. Affected by multiple factors such as pig supply cycle and epidemic situation, the domestic pork market has attracted much attention this year, from pig breeding in the supply chain, purchase and delivery to consumption on the table.

  On September 5, the data released by the Ministry of Agriculture and Rural Affairs showed that from August 26 to September 1, the average purchase price of pigs in designated pig slaughter enterprises above designated size was 26.00 yuan/kg, up 6.86% from the previous week and 82.97% from the same period last year. The average ex-factory price of white striped meat was 33.05 yuan/kg, up 6.34% from the previous week and 75.33% from the same period last year.

  China, as a big pork consuming country, the rising pork price has attracted great attention from the government, and the pork supply guarantee has been promoted to the height of "concerning people’s livelihood and the overall situation". Since August, the executive meeting of the State Council has repeatedly mentioned "measures to ensure the supply and price stability of pork". In September, Hu Chunhua, Vice Premier of the People’s Republic of China went to Sichuan Province and Heilongjiang Province for on-the-spot supervision, stressing the need to vigorously promote the stability and recovery of pig production in the main producing areas. The State Council took the lead, and many government departments cooperated with each other, and made a series of policies on loan discount, insurance coverage, improved seed subsidies, pig breeding land and so on.

  Support policies such as loan subsidies were introduced.

  As a representative of farmers in the town, Liu Jian attended the communication meeting on pig breeding held by the xiushui county Municipal Government on September 5th, and he looked forward to the follow-up support of government departments in subsidies and loans. Now, there are hundreds of pigs in his farm, and the disinfection control is becoming more and more strict, and even no outsiders are allowed to enter the pig factory.

  Due to the good epidemic prevention measures, Liu Jian’s farm has not been affected by the epidemic. On the contrary, with the high price of pork, it is still profitable. However, he has no idea whether to increase investment in farming next. Other farmers are also watching. "It depends on how the government issues documents, and now many things are being promoted."

  The decline of pig production and the decrease of stock are emerging. According to the data released by the National Bureau of Statistics, in the first half of 2019, 313 million pigs were slaughtered nationwide, a decrease of 20.75 million heads or 6.2% compared with the same period of the previous year; The output of pork was 24.7 million tons, a decrease of 1.43 million tons or 5.5%. At the end of June, there were 348 million live pigs in China, a year-on-year decrease of 61.43 million or 15.0%.

  As the major pig production provinces in China, Sichuan Province and Heilongjiang Province have become the key stations for government inspection. On September 6th, Hu Chunhua, Vice Premier of the People’s Republic of China pointed out that ensuring the supply of pork is one of the most urgent tasks in the work of agriculture, countryside and farmers.

  The "vegetable basket" plan focusing on pork production has been included in the assessment of local governments. Prior to this, on August 30th, a national video conference on stabilizing the supply of live pig production guarantee market was held in Beijing. Hu Chunhua pointed out that pig production in all localities should be strictly in accordance with the requirements of the overall responsibility of the province and the mayor’s responsibility system of "vegetable basket", and resolutely accomplish the goal of stable production and supply of pigs.

  Major provinces have also put forward production targets for 2019-2022. Taking Shandong Province as an example, it is estimated that 2.8 million pigs, 3.2 million pigs and 4.2 million pigs will be transferred out in 2019, 2020 and 2022 respectively. Jiangsu, Zhejiang, Guangdong and other provinces have proposed that the self-sufficiency rate of pigs in the province will be stabilized at over 70%.

  Production tasks were quickly spread from major provinces to various cities, and some provinces even explicitly required the minimum pig slaughter in various cities. In order to fully mobilize the enthusiasm of farmers and solve the problem of pork shortage in the domestic market, several major government departments have joined hands to "make moves".

  For example, the Ministry of Finance and the Ministry of Agriculture and Rural Affairs jointly issued a notice a few days ago, proposing a series of policies, such as improving the temporary loan discount policy for breeding pig farms and large-scale pig farms, increasing the incentives for pigs to be transferred out of large counties, increasing the insurance coverage of pigs, supporting the implementation of subsidies for improved varieties of pigs, and strengthening provincial financial co-ordination.

  On August 30th, the Department of Agriculture and Rural Affairs of Jiangxi Province issued the "Announcement on the Review of Discount Loan for Working Capital of Breeding Pig Farms and Large-scale Pig Farms", saying that after the review by Jiangxi Supervision Bureau of the Ministry of Finance, it is planned to give discount loans to 224 breeding pig farms and large-scale pig farms, with a total amount of 22,548,900 yuan.

  Other places have also come up with "real money and silver." According to Farmers Daily, Sichuan Province plans to arrange 300 million yuan of financial funds in 2019, carry out standardization construction in an all-round way, encourage and support qualified farmers to expand production, and focus on supporting the layout and development of leading enterprises in Sichuan. Jiangsu Province allocated 261 million yuan for the protection of pig germplasm resources and subsidies for the purchase of breeding pigs in large-scale pig farms, and supported key breeding counties and large-scale pig farms to improve epidemic prevention facilities.

  Guangdong Province arranged 20 million yuan to implement discount loans for working capital of breeding pig farms and large-scale pig farms, 80 million yuan to support the transformation and upgrading of the slaughtering industry, and 100 million yuan to support the construction and standardization of facilities for recycling manure in livestock and poultry farms.

  Henan province is also quite "generous". The province proposes to use 300 million yuan of pigs as a whole to transfer incentive funds from big counties, focusing on supporting the "two games" to improve infrastructure and epidemic prevention conditions; We will implement the "two-game" loan discount policy and give 110 million yuan of discount subsidies to 154 pig-raising enterprises. The provincial finance will also allocate 170 million yuan to support the standardization of live pigs in non-livestock counties.

  In addition, Zhejiang Province has launched a consumption subsidy mechanism for the needy. From April to July, the province has distributed a total of 210 million yuan of price subsidy funds, and arranged more than 1 billion yuan in the rural revitalization investment fund to increase financial interest subsidies to ensure the capital needs of large-scale aquaculture entities.

  breedheadEnterprise accelerated layout

  The supply of pork is in short supply, and a number of policies have escorted it, which directly led to a sharp rise in the stock prices of related listed aquaculture enterprises. According to the statistics of Choice, as of September 3, the total market value of the pork concept sector of A shares has soared from 424.7 billion yuan to 849 billion yuan in just one year, with an increase of nearly 100%.

  Although pork concept stocks are favored in the capital market, it is difficult to ignore the breeding cost and operating pressure of enterprises due to multiple factors. Feedback to the financial report is that in the first half of this year, the performance of head enterprises appeared "two days of ice and fire", and the net profit of Wenshi shares and New Hope increased substantially year-on-year, while the net profit of Mu Yuan shares, Zhengbang Technology and Yurun Food all fell or even lost money.

  Overall, the industry’s pig production capacity has weakened. According to the data of the Ministry of Agriculture and Rural Affairs, in July 2019, the number of live pigs in 400 monitoring counties nationwide decreased by 32.2% compared with the same period of last year, and the number of fertile sows decreased by 31.9% compared with the same period of last year.

  "It is not clear whether the local government has issued production targets to the company." A person from the securities affairs department of a pig breeding listed company told The Paper that in the first half of this year, the company attached great importance to epidemic prevention safety and accumulated effective experience; In the second half of the year, we will take the expansion strategy as the development direction, continue to implement the breeding planning objectives during the year, and take the opportunity to increase the market share. "We are still optimistic about the prospects of the breeding industry."

  Faced with the current market situation, many head breeding enterprises are also accelerating their layout. Since this year, a number of cooperative projects have been launched one after another, including the pig breeding industrialization projects that New Hope Group signed with Guang ‘an, Sichuan, Pengshui, Chongqing and ziyang, Sichuan, respectively, with an annual output of 3 million, 1 million and 2 million pigs.

  Wen’s shares are also important participants. In August 2019, the company signed the "Two Million Project" project with Guoyang County, Bozhou City, Anhui Province, that is, 1 million pigs breeding+1 million pigs slaughtering and processing, with a total investment of about 2 billion yuan, with an annual output value of about 3 billion.

  Also in August, Mu Yuan announced that it planned to slaughter 13 million to 15 million pigs in 2019, and raised a net fund of 2.46 billion yuan, which was mainly used for five pig breeding construction projects in Inner Mongolia, Heilongjiang, Liaoning and Jilin, with a total annual slaughter target of 2.1 million pigs.

  On September 3rd, Zhongtai Securities released the research report "Analysis on Key Indicators of Pig Stock Interim Report", which showed that the productive biological assets of head enterprises were flat or rising at the end of the second quarter of this year, reflecting that the current epidemic prevention and control has made good progress and the production capacity began to recover.

  Stimulate the enthusiasm of small and medium-sized farmers

  "It is equally important to stabilize the market price of pork, support the cultivation of large and medium-sized leading aquaculture enterprises, and stimulate the production enthusiasm of small and medium-sized farmers and farmers." Pan Xiangdong, vice president and chief economist of New Era Securities, said in an interview with The Paper that it is expected to take a process for small and medium-sized aquaculture enterprises at the grass-roots level to truly feel the series of support measures launched by the state.

  For small and medium-sized farmers and farmers, the policy that has the most direct impact on them is: In August, Premier Li Keqiang made it clear at the executive meeting in the State Council that the local authorities should immediately cancel the regulations on the prohibition and restriction of raising pigs beyond the laws and regulations, develop large-scale farming, and support farmers to raise pigs.

  A number of government departments are rectifying the excessive policies of banning and limiting support in rural areas in previous years. In 2016, the State Council issued the Notice of the "Thirteenth Five-Year Plan for Ecological Environment Protection", requiring all regions to close or relocate livestock and poultry farms (communities) and specialized farming households in the no-breeding areas according to law before the end of 2017, and vigorously support the standardized transformation and construction of livestock and poultry farms (communities).

  Since then, many provinces across the country have successively started the relocation of pig-forbidden areas. Coupled with the swine fever epidemic since 2018, the number of small and medium-sized farmers has decreased, and retail farming has almost cleared. According to the data of Sky Eye Survey, there are more than 1.4 million "pig" enterprises in China at present, and they have maintained a high growth rate in the past decade. However, the number of cancelled and revoked enterprises is also increasing year by year. In recent years, there are more than 40,000 related cancelled enterprises every year.

  In order to solve the problem and actively respond, a series of effective measures are being introduced. According to Xinhua News Agency, since August 31st, the Ministry of Agriculture and Rural Affairs, together with the National Development and Reform Commission, the Ministry of Finance, the Ministry of Natural Resources, the Ministry of Ecology and Environment, the Ministry of Transport, China Banking and Insurance Regulatory Commission and other departments, have conscientiously implemented the decision-making arrangements of the CPC Central Committee in the State Council, and many departments have successively issued documents and issued 17 policies and measures to support the development of pig production.

  On September 4th, the General Office of the Ministry of Natural Resources issued the Notice of the General Office of the Ministry of Natural Resources on Issues Related to Safeguarding the Land for Pig Breeding, and urgently issued the land policy for pig breeding to ensure the demand for pig breeding land. On September 5, the Ministry of Ecology and Environment responded for the first time, demanding that all localities should not expand the designated scope of no-breeding areas, and should not restrict the development of pig industry or reduce the production capacity of pigs in violation of laws and regulations on the grounds of improving the ecological environment.

  "At present, China’s pig industry is still in the stage of increasing industrial concentration. The adjustment of national environmental protection policies has little impact on the operation of large-scale listed companies. Enterprises have formed their own environmental protection systems, and the overall business strategy will not change." A person from the securities affairs department of the above-mentioned pig breeding listed company said.

  Small and medium-sized aquaculture enterprises are facing certain pressure. The chairman of a breeding enterprise in fengqiu county told The Paper that last year, affected by the epidemic situation, the local government guided farmers to buy insurance, and the insurance premium for each pig was 40 yuan. For dead pigs weighing more than 200 kilograms, the insurance company also paid for 200 kilograms at 4 yuan per catty. Coupled with the cost of breeding, such as feed, electricity, labor, etc., it is still a loss. Many small and medium-sized farmers in the county have changed careers this year.

  In order to enhance farmers’ ability to resist risks, recently, the Notice on Supporting the Work of Stabilizing the Supply of Live Pig Production Security Market issued by the Ministry of Agriculture and Rural Affairs of China Banking and Insurance Regulatory Commission, China mentioned that "the policy insurance policy for live pigs should be improved. Improve the insurance coverage of fertile sows and fattening pigs, temporarily increase the insurance coverage of fertile sows from 1,000-1,200 yuan to 1,500 yuan, and increase the insurance coverage of fattening pigs from 500-600 yuan to 800 yuan. The specific matters shall be handled according to the relevant requirements of the financial department. "

  Pan Xiangdong believes that one of the most needed safeguards for farmers or aquaculture enterprises at present is the preferential policies to encourage pig raising, including financing policies and fiscal policies, and the policies should be stable. Secondly, we should rationally plan the land for agricultural breeding in order to adapt to the new era of agricultural industrialization, improve industrial concentration and production efficiency, and better manage the supply of agricultural products.
