Abstract攀西地区位于四川省西南隅,包括渡口市和凉山彝族自治州,属四川省国土综合开发的重点规划地区。境内滑坡灾害比较严重。调查结果表明,全区内方量在50万立方米以上的大型自然滑坡和滑坡群达220个,1万立方米以上的人为滑坡51个(图1)。有些滑坡对该区城镇、工矿和农村造成一定的灾害,给人民生命财产酿成重大的损失。 
Other Abstract The Dukou-Xichang region is located in Southwest Sichuan and belongs to Hengduan Mountainous region, where are 220 natural landslides of 500000m3 and 51 man-made landslides of 10000m3.The landslides are distributed in the middle or low reaches of the incised valleys. The natural landslides are concentrated in the strong uplifted area and then the large natural landslides distributed in the fault valleys are few. They are alomst are distributed in the fault slacking belt, especially the intersecting area. Because of the litholo-gical characters, the middle and small epi-lanslides occur in Xigeda Formation clay rock and losse accumulation horizon. The large inter-nallandslides occur in the slacking sandy shale strata. The landslides in limestone strata are mainly bedding landslides and cave-collapse landslides.Exception, in this region, the rainfall is abundant, the rainfall intensity is strong, and the groundwater is active, thus causing formation of landslide. Owing to the human activities for economic development, a number of landslides occurred in this region in recent years.
