摘　　要：随着化肥和农药的大量使用,农业非点源污染已经成为全球水污染的主要来源。从农田景观生态结构与非点源污染的关系入手,综述了影响农田非点源污染的因素复杂多样,不同化肥、农药使用量、使用方式和季节,农田耕作措施、灌溉方式在非点源污染形成中起了不同作用;并分析了通过农田景观设计来控制非点源污染。With the practice of chemical fertilizer and pesticides, agricultural non- point source pollution has become the main resource of global water pollution. Many factors can affect the formation of non point source pollution, including amount, practical ways and season of different fertilizers and pesticides, measures of farmland cultivation and irrigation methods. We also analyzed the fact that non-point source pollution was controlled through design of farmland landscape.
