Abstract: The problems of agricultural environment in China were summarized systematically from the aspects of agricultural natural resources, eco-environment destruction, and environmental pollution. Their causes were analyzed, and the countermeasures were put forward. As a whole, our agricultural natural resources were in shortage and polluted heavily, agro-ecological environment destruction was quite serious, agricultural non-point pollution from fertilizers, pesticides, and plastic film became more and more serious, and the improper disposal of straw, contamination of livestock and birds breeding, rural living pollution, contamination by township enterprises, and the pollution transferred from cities deteriorated agricultural environment. These problems were correlated with some agricultural policies to a large extent. In addition, the imperfect legislation in agro-environmental protection, the lack of effective law execution, the weak awareness in environmental protection, and the imperfect environmental management system were all the main reasons of agro-environmental problems. Based on these causations, several countermeasures were put forward to solve the problems of agro-environment, i.e., to develop strategic environmental assessment of agricultural policy, pay attention to ecological construction, promote the resources to be used in high efficiency, develop eco-agriculture, control the inputs of agro-chemicals reasonably, implement cleaner production in planting industry, enhance the inspection and management of the contamination of livestock and birds breeding, constitute prompting mechanism, reduce agricultural non-point source pollution, establish regulatory mechanism of rural environment, and strengthen publicity and education to improve the environmental awareness of farmers.
