摘要:随着我国经济的快速发展，农业面源污染已成为我国环境污染的主要原因之一。农业面源污染制约农业可持续发展，已成为亟待解决的环境问题。目前，造成农业面源污染的原因主要是化肥农药的过量施用和流失，畜禽和水产养殖业污染，水土流失，作物秸秆大量废弃以及农膜污染。农业面源污染具有分散性、广泛性、随机性等特征，对土壤、水体、大气造成负面影响。本文针对农业面源污染问题，从生物、物理、化学以及农业管理等角度提出了相应的防治对策及措施，以期有效治理农业面源污染，保护环境，促进农业可持续发展。

AbstractAgricultural nonpoint source pollution is the main factor to the environmental pollution in rural China now with the development of economy in China. It has gained the attention of the government and scientist in the country, and also is the main factor to restrain the agricultural sustainable development. At present, the reasons are list as follow: chemical fertilizer and pesticide and excessive application; Livestock and aquatic products pollution; soil erosion; a majority of strews abandoned; agricultural plastic film pollution. It has the characteristics of dispensability, univ ersality and randomness, which have negative effects on soil, water and air. In terms of biological chemistry and physics and agricultural management, this paper proposes countermeasures to control agricultural non-point source pollution, protect the environment, and promote the sustainable development of agriculture.
