The border areas of Sichuan,Yunnan and Guizhou Province are greatly hit by landslides.There are 1.2million hidden dangerous points experiencing geological disasters,which have threaten more than 100million livesand property security,and have negative effects on production,livelihood security of local people and sustainable development.The five evaluation factors of gradient,relative height distance to active fractures,annual average rainfalland annual average number of heavy rain days are selected to calculate their contribution weights.With the support ofGIS,the map for landslide hazard evaluation in the area is drawn by using superposition method and the contributionrate model.Results show that:（1）The study area（about 19.18×104 km2）contains very highly dangerouszone（3.92×104 km2）,highly dangerous zone（4.34×104 km2）,moderately dangerous zone（4.58×104 km2）,slightly dangerous zone（3.92×104 km2）and stable zone（2.42×104 km2）.The areas of very highly,highlyand moderately dangerous zones account for 67.00% of the total area.（2）Very highly dangerous zone ismainly located in the two sides of deep fractures in Xiaojiang-Anning River and deep valleys of Jinsha Riverand Yalong River,which implies that active fractures and landform play a macro-control effect on landslides.（3）The population in very highly and highly dangerous zones is about 11.5231 million,accounting for32.17%of the total,and GDP is about 41.988billionyuan,accounting for 28.75%of the total.So,it is essential to strengthen the capacity of preventing and reducing the geological hazards in the area.
