摘要
面源污染已成为造成河流、湖泊、水库污染的主要原因,有效控制面源污染对于改善水环境质量具有十分重要的意义。针对云南山区面源污染的现状,通过分析面源污染形成的原因和治理中存在的问题,认为微区域集水系统具有拦截和控制山区坡耕地地表径流、增强山坡水源涵养功能和控制农田径流等多项功能,能够实现生态治污、有效控制面源污染的目的。
Area-source pollution has become the main reason of pollution in rivers,lakes and reservoirs.Effectively control area-source pollution that is of very important for improving water environment.The study shows that micro-area water-harvesting technical system has the functions of intercepting surface runoff on sloped lands,reinforcing water conservation function of slopes,and controlling agricultural runoff,based on present status of area-source pollution of mountainous region in Yunnan,through analysis on the forming reasons of area-source pollution and the existing problems in pollution control.The application of micro-area water-harvesting technical system is beneficial to control area-source pollution in a effective and ecological way.
