Xichang City was located in the basin of Anning River in western Sichuan.The geological conditions were complex,and the ecological environment was vulnerable.The geological hazards,such as landslide debris,threatened the residents' lives,their property security and the local economic development.The article analyzed the development of 153 geological hazards in different types in Xichang City,and summarized the development and distribution patterns of the geological accidents based on basin features,elevation and occurring periods.The affecting or controlling factors of the geological disasters in Xichang City,including topography,structure,rock mass structure,earthquakes,rainfall and human engineering activities,were analyzed and summarized.In the end,the paper proposed some scientific and reasonable prevention suggestion according to the geological hazard types and their developmental and distribution characteristics in Xichang City.
