摘要
水土流失是三峡库区重要的生态环境问题,重庆市三峡库区的水土流失问题则更为严重。在遥感和GIS技术的支持下,对重庆市三峡库区水土流失的数量特征、强度特征、空间分布特征,及水土流失的动态变化特征进行分析,进而对研究区的水土流失类型进行分区,并对每一分区的水土流失特征进行分析与描述,提出水土流失治理与防治的主要措施。
Soil and water loss is the serious environmental problem in Three Gorges Reservoir area, and it is more serious in Chongqing. Base on the RS and GIS, the soil erosion characteristics, spatial distribution, dynamic changes, and the regionalization of soil and water loss are analyzed in the paper. Furthermore,the soil and water loss characteristics of each sub-area, and the management measures are also described in the paper.
