以乌东德水电站坝区一典型区为例，详细介绍了土地利用现状及植被覆盖度的解译、坡度因子的提取、水土流失等级的划分及各专题数据库的生成，分析了试验区土地利用、植被覆盖度、坡度及土壤侵蚀强度的分布状况，为金沙江水库建设、水土流失自动化监测及信息化管理提供依据和参考。

One representative district in the dam of Wudongde Hydroelectric Power Station is selected as an experiment and demonstration area, the region situation of land use, vegetation coverage, slope factor extraction, classification of soil and water loss grade and the generation of all special subject database are introduced in detail, and the distributions of land use, vegetation coverage, slope and soil erosion intensity are also analyzed. All of these will provide bases and references for reservoir construction, automatic monitoring of soil and water loss and information management in Jinshajiang River.
