摘要
农业非点源污染是一种重要的环境污染方式,由于其污染的时空范围广,不确定性大,污染严重,对其治理及管理的难度也较大。本文论述了农业非点源污染对环境的影响,并提出了治理农业非点源污染的生态工程措施,如发展生态农业和生态施肥技术、污水处理和固体废物生态工程技术、水土保持生态工程技术、建立植被缓冲带和湿地生态工程等。
Agricultural non-point source pollution is an important form of environment pollution,Because the spatial-tempouval range of pollution is wide;uncertainty is great;the prevention measure is difficulty.The effect of agricultural non-point source pollution is discussed,and some measures are analyzed,such as developing ecological agriculture,retaining soil and water,establishing vegetation buffering zones and wetland ecological engineering.
