三峡地区生态环境治理保护对策

三峡地区是全国山地灾害频发的地区之一，而由于工业的发展，沿江域镇环境污染已对长江水质构成威胁，三峡建库后，随着库区水位的抬高，长江流速变缓，排污能力减弱，易在城镇岸段和回水区形成污染带，为此，建议持续实施农业综合开发工程，扩大自然保护区，治理水土流失，改善农业生态环境，加大“长江上游防护林工程”、“长江上游水土保持工程”、“中低产田改造工程”的投资比重和治理范围，对于山地灾害防治的重点为地质灾害严

Measures for harnessing ecologic environment in Three Gorges region

Three Gorges region is one of hilly regions of frequent disasters in china.With development of industries in the Yangtze valley,the pollutants from the cities and towns along the Yangtze river have been threatening the Yangtze's water quality. After impounding of Three Gorges reservoir,the raise of reservoir water level will lead to reduction of both river flow velocity and river pollutant dispersion capacity,which will easily result in pollution zones in those reaches close to cities and towns and reservoir backwater area. In view of this, continuously to build the comprehensive agricultural development works,to enlarge the natural protection area,to control the soil and water loss,to improve the ecologic agricultural environment are recommended.In addition,the investments for forest protectron and soil and water conservation in upper Yangtze region as well as median/low-yield farmland reclamation in the reservoir area should be increased,and the ranges of these works should be enlarged. Deformed rock masses and potential landslides located in the reservoir banks should be ranked as focal points of hilly area disasters controlling. The key of harnessing environmental pollution in Three Gorges region is to control and treat various pollutants from cities and towns to protect the water quality in Three Gorges reservoir.
