向家坝水电站位于四川省与云南省交界的金沙江峡谷处。从地层岩性以及地貌特征2方面，分析向家坝库区滑坡的发育规律，并基于GIS空间分析方法，使用滑坡面积与滑坡数量2个参数对滑坡地层岩性、相对高差及岸坡结构等进行统计分析，结果表明：滑坡多发育在1）泥页岩为主夹粉砂岩和砂岩地层中；2）地形相对高差在0～100 m之间；3）岸坡结构为缓倾顺向岸坡与缓倾斜向岸坡处。
嚮傢壩水電站位于四川省與雲南省交界的金沙江峽穀處。從地層巖性以及地貌特徵2方麵，分析嚮傢壩庫區滑坡的髮育規律，併基于GIS空間分析方法，使用滑坡麵積與滑坡數量2箇參數對滑坡地層巖性、相對高差及岸坡結構等進行統計分析，結果錶明：滑坡多髮育在1）泥頁巖為主夾粉砂巖和砂巖地層中；2）地形相對高差在0～100 m之間；3）岸坡結構為緩傾順嚮岸坡與緩傾斜嚮岸坡處。

Xiangjiaba Hydropower Station is located at Jianshajiang strait between Sichuan and Yunnan. This paper analyzes the rules of development of landslide in Xiangjiaba reservoir area from formation lithology and geomorphic features,and performs statistical analysis for formation lithology of landslide, relative elevation difference and bank slope structures,etc.by means of 2 parameters,i.e.landsliding area and number based on GIS space analysis method.The results show that more landslides develop in 1 ) stratum of mud shale with siltstone and sandstone included;between 2 )0 ~100m relative elevation difference of terrain;and at 3)bank slope structures being gentle dip slope and gentle diagonal slope.
