长江上游三峡库区坡耕地面积广,水土流失量大,对当地环境和经济社会的发展造成了严重危害。通过建立库区"生态修复、生态治理、生态保护"三道防线,并开展库区消落带的治理,生态清洁型小流域水土流失得到有效控制。结合生态清洁小流域建设的一般原则和技术要求,对三峡库区的生态清洁小流域治理模式进行了探讨,并针对当前生态清洁小流域建设和管理存在的不足和问题提出了相应的建议。 更多还原
 

The local environment and the development of economy and society are exposed to the threats, resulting from alarge area of the sloped farm lands and the significant loss of soil and water in the TGP reservoir area of upper YangtzeR iver. We have effectively controlled the soil and water loss in eco-clean small watersheds, through building up the three lines of defense such as “ecological rehabilitation, ecological harnessing ande cological protection”, as well as regulating the fluctuated zone of the reservoir area. We study the control mode of eco-clean small watersheds in TGP reservoir area, combining with general principles  and technical requirements, and put for ward some suggestions toimprove the control mode of the watersheds.
