Agricultural environmental monitoring can not stop at obtaining such information, but also summarize and analyze the information, make current or pre-assessment of agricultural environmental quality, and sometimes recourse to the root causes of pollution (or damage), and make environmental accident decisions. Suggestions and prevention measures. At the same time, the agro-environmental monitoring department will continue to conduct research on monitoring methodology. Agricultural environmental monitoring is a new development work. There are many problems in methodology that need to be studied. Only by combining monitoring tasks with continuous research can we improve the level and meet modern environmental management and agricultural production to monitor the agricultural environment more and more. Claim. The general purpose of agricultural environmental monitoring is to serve the environmental protection and agricultural economic construction. It is not only a part of environmental protection work but also part of the agricultural economic work.
2. Development of agricultural environmental monitoring The preliminary understanding of the importance of the quality of agricultural environment for human beings can be said to have been long-standing. The Chinese ancient book “Gao Gong†divided our country into Kyushu, which stipulated the level of land at that time. "Qi Min Yao Shu" advocates that agricultural production should "measure the amount of land" when it goes along with the sky, and points out that "there is no way to get back, but there is no gain". But after the industrial revolution, especially after the Second World War, Yamayu. With the development of science and technology, humanity has begun to unilaterally believe in its ability to “acquire it from natureâ€, coupled with the pressure of rapid population growth in the world. Humankind has blindly fallen into the effort to develop and use natural resources and develop industrial and agricultural production by all possible means. in. These not only bring about rapid exhaustion of renewable resources and impossible renewable resources, but also bring about problems of environmental pollution and imbalance of ecological balance. This problem has been noticed earlier in countries with rapid development of science and technology. For example, in the early part of the century, the United States created a “dust-blasting era†due to the use of predatory methods to open land and use land; in the thirties, a water and soil conservation bureau was established to investigate environmental damage, take measures for soil and water conservation and ecological restoration, and The effect was received. In the late 1960s, the U.S. Department of Agriculture established the Huanpo Sand and Prison Institute. It conducted a large number of surveys and researches on environmental quality issues. From 1940, the Japanese Ministry of Agriculture and Forestry began to pay attention to the investigation and study of "the causes and prevention measures of agriculture-related damage caused by mining industry" and launched the "Water Pollution Joint Research Promotion Conference"; after the 1950s and especially in 1968, it was confirmed that bone pain was due to soil. After the pollution caused by the pot, the “Study on Protecting the Environment for the Production of Water for Agriculture and Forestry Water†was carried out in 1968-1971. In the future, soil pollution surveys and detailed surveys in some areas were carried out nationwide; in 1983, the original agricultural technology research was conducted. The institute was changed to the Institute of Agricultural Environmental Technology. With this as the center, it contacted agricultural inspection sites in all counties in the country and formed a network for agricultural environmental monitoring, research and promotion. Duan Dian began using methylmercury-containing dicyandiamide pesticides in 1940. Through monitoring studies, it was discovered that birds died unclearly and some species were even extinct. In 1968, Sweden solemnly proposed to the United Nations to convene the World Conference on Human Environment.
The monitoring of agricultural environment in our country is much later than that of developed countries. However, it started at the same time as China's major environmental protection work. On December 26, 1970, the late Premier Zhou Enlai summoned the responsible comrades of the then Ministry of Agriculture and Forestry, the Ministry of Health, and the General Staff Department of the Second Department to discuss the topic of “pollutionâ€. He said: “Industrial pollution is a new topic. When industrialization starts, this issue becomes big. The agriculture and forestry departments should raise this issue, and agriculture and forestry must also require air and water." According to Premier Zhou's instructions, our agricultural department established the Research Institute of Environmental Protection of the Institute of Biological Sciences of the Academy of Agricultural Sciences in 1971, and started investigation and research on agricultural environmental pollution. In 1979, the Ministry of Agriculture extended the room to the Environmental Protection Research and Monitoring Institute of the Ministry of Agriculture, Animal Husbandry and Fisheries and set up a professional monitoring room under the Ministry of Agriculture. In 1984, the Ministry of Agriculture approved the expansion of the monitoring room as a national agricultural environmental monitoring station. At the same time, agricultural environmental monitoring stations have also been established throughout the country. Up to now, more than 100 provinces, prefectures, and municipal-level stations have been established. Only 29 provinces and cities in China have left a few provinces without stations. The rapid development of the establishment of the station shows that China attaches great importance to the work of agricultural environmental protection, and also shows the importance of agricultural environmental monitoring to the country’s social and economic development.
Local agricultural environmental monitoring stations have been building and working for many years and actively carried out environmental monitoring, environmental quality assessment, and environmental pollution accident adjudication. Many stations have also combined the actual needs of the development of local agricultural economy, carried out research, demonstration, promotion of ecological agriculture, and the research and management of non-polluted agricultural products, and used environmental monitoring and scientific research results to directly serve agricultural production. Many local stations submitted annual agricultural environmental quality reports to their superiors, and 198 were written throughout the country. The two Agricultural Environmental Quality Reports of 1983 and 1983 contributed to our country's economic and environmental plans.
3. Benefits of agricultural environmental monitoring The agricultural environmental monitoring is an important task for social and economic development and environmental protection. It is an indispensable basic link in the construction of material civilization and spiritual civilization in modern countries. Therefore, this work will have obvious economic, social and environmental benefits.
Now everyone's understanding of the environmental benefits and environmental benefits of environmental monitoring is still relatively clear; however, their economic benefits are not necessarily conclusive, so I would like to focus on economic issues.
If you want to invest in any social undertaking, initially preparing a monitoring station for more than 30 people, including laboratories and basic equipment, may require about one million yuan (excluding dormitory). After investing, it is impossible to recover costs as quickly as the business unit. However, if its work is carried out well, it will bring many direct economic benefits, or avoid major pollution losses. Some examples of direct economic losses caused by lack of monitoring of the agricultural environment in the past are quite striking. For example, in the rural area of ​​Tianjin, in 1974, the farmland was flooded with water that was heavily polluted by acids, alkalis, mercury, benzene, and phenol and was not monitored. Acres of wheat victims, of which an area of ​​28,000 acres will be expropriated, and economic losses of no less than 3 million yuan, can be invested in the construction of three agricultural environmental monitoring stations. In 1980, Wendeng County in Shandong Province applied phosphorus-containing chloral aldehydes to make 50,000 mu of peanuts and corn victims, and the direct economic loss was more than 8 million yuan. There are many such examples in the country. Statistics before the Second National Environmental Conference in 1983: Only industrial “three wastes†polluted farmland caused grain production reductions of more than 100 billion kilograms per year, equivalent to 1 billion pounds per pound. There are more than 100 agricultural environmental monitoring stations at all levels in our country, all of which are worth one million yuan. If we take one billion yuan in losses every year, our country's daily agricultural environmental protection work (including management, scientific research, monitoring and education) may not be used up. If we take back the other four-fifths of the investment in agricultural environment construction, especially for tree planting, grass planting, and ecological agriculture development, then our agricultural environmental quality will be improved somewhat and we will receive a large increase in production. benefit. If the agricultural environmental monitoring and management are carefully managed, the above pollution losses are likely to be avoided, at least a considerable part of which can be avoided. Or, after investing in agricultural environmental monitoring, compensation can first be avoided from pollution losses. In addition, if the calculation of the benefits of reducing the pollution of agricultural products on the health of the people in urban and rural areas of the country and on foreign trade, the economic benefits will be even more pronounced. Over the years, the development of agricultural environmental protection work is not fast enough. It may be related to the failure to seriously calculate the economic account and see the benefits of agricultural environmental protection work. All countries and counties count this account, and investment in agricultural environmental protection may be easier to manage.
After investing, how to use investments more effectively to make them more effective is often not just about economics, but also about professional and technical issues. In the monitoring work, the station is first built where it is needed most, and the monitoring points are arranged in the places where the problems can be most reflected, prioritized, the key positions are grasped, the key points are grasped, and the first step or the central link is grasped. Related to benefits. Every monitoring worker must always think that the monitoring work is ultimately to serve social and economic development. Just like measuring the nitrogen, phosphorus, potassium, rainfall, evaporation, and freezing of ice, etc., it serves the agricultural production from another perspective. Production, and sometimes industrial and other activities, provide the necessary environmental information. Although monitoring sometimes contradicts current production interests, it is ultimately unified and essential to production.
Development and Management of Agricultural Environmental Monitoring in China
1. Objectives and Tasks of Agricultural Environmental Monitoring The direct purpose of agricultural environmental monitoring is to observe, test, and use physical, chemical, biological, and other means and technologies to observe, test, and test the physical, chemical, and biological aspects of agriculture through survey visits. Factor status and changes to obtain information on the quality of the agricultural environment. These information materials include surveys, observations and reports on the agricultural environment, various test data, video materials, aerial photographs, satellite images, and other remote sensing data. These are important data that reflect the quality of the agricultural environment.
