摘　　要：隔河岩库区地处鄂西山区,地质环境条件复杂,属地质灾害易发地带,其中滑坡是库区最主要和常见的灾害。基于区内以往地质灾害调查资料统计分析的基础上,总结了滑坡的时间、空间分布特征,认为地形地貌、地层岩性、大气降雨和库水位变化等是库区滑坡灾害的主要控制因素。Geheyan reservoir area is located in the western Hubei moutainous area, where the geological conditions are complex, which is geological disaster easy-happening area. Based on the region＇s previous geological disaster survey statistics and analysis, the paper summarizes temporal and spatial distribution characteristics, thinks the topography, lithology, precipitation, changes of the reservoir water level of landslide are the main control factors of landslide disaster in reservoir area.
