摘要
非点源污染的本质是农村生态系统的严重失调 ,生态工程技术是进行流域生态修复、强化物质循环的有效方法 .非点源污染的治理策略有控制径流污染和控制源头污染两个方面 .本文介绍了多水塘系统、植被缓冲带、湿地系统、生态农业、坡面生态工程和污染物生态处理 6种生态治理技术 .它们的有机结合可形成控制非点源污染的流域生态工程 .执行时 ,应该因地制宜 ,还要加强资金、管理和教育的投入 .
Nonpoint pollution from rural areas is the results of the ecosystem degradation,and ecological engineering technologies are good ways for the restoration of watershed and enhancing material cycling.There are two types of treatment strategies:to control the polluted runoff and to reduce the pollutants from the sources.Six control technologies are introduced and they are multipond systems,grassed filter trips,wetland systems,eco-agriculture,slope ecological engineering,ecological treatment of wastewater and soild waste.These technologies need to be combined systematically in order to form a watershed ecological engineering.In the control program,it is important to use countermeasure suitable to the local conditions.In addition,the input of sufficient investment,management and education is necessary.
