After more than ten years of hard work, the agricultural environmental monitoring network centered on the Agricultural Environmental Monitoring Station of the Ministry of Agriculture has been basically established, including provinces, cities, autonomous regions, and key counties. In accordance with the National Environmental Monitoring and Management Regulations6, the Agricultural Environment Monitoring Network is a secondary network of the National Environmental Monitoring Network, including the Agricultural Environmental Monitoring Center, the Fisheries Environmental Monitoring Center, and the Grassland Environmental Monitoring Center.
Agricultural Environment Monitoring Station This network, through routine monitoring of the agricultural environment, acquires more than 100,000 monitoring data on air, water, soil, and biology each year, and is an important source of information for the National Environmental Status Bulletin. So far, in addition to the Ministry of Agriculture’s Environmental Monitoring Center, four provincial-level agricultural environmental monitoring stations in Shandong, Hubei, Jilin, and Yunnan have passed the ministerial-level metrology certification, with nearly 10 in Chongqing, Ningxia, Inner Mongolia, Sichuan, Shaanxi, and Beijing. Provincial stations passed provincial measurement certification, and the monitoring capacity and monitoring levels have been significantly improved.
Agricultural Environment Monitoring Station Development of China's Agricultural Environment Monitoring System
Environmental monitoring as an important part of environmental protection has also been rapidly developed. The environmental monitoring work of China's agricultural environmental monitoring stations began in 1973. After more than 20 years of development, the nationwide environmental monitoring network was gradually established with the participation of 54 provincial and ministerial level environmental monitoring stations based on the EPA system and 17 departments. The network includes more than 2,600 monitoring stations at the national, provincial, municipal and prefecture levels, and approximately 20,000 monitoring personnel.
