摘　　要：册亨县地貌以中低山为主,独特的地质环境孕育了大量的地质灾害,严重威胁人民生命财产安全。在全面分析孕灾条件的基础上,选取高程、坡度、相对高差、工程地质岩组、斜坡结构、微地貌类型6个相互独立的指标,运用信息量模型评价册亨县滑坡易发性,评价结果与实际情况基本一致,研究结果可为相似地区滑坡易发性评价提供借鉴。With a predominantly low to medium mountainous landscape,the unique geological environment of Ceheng County has bred a large number of geologic hazards,which seriously threaten the safety of people’s lives and properties.On the basis of comprehensively analyzing the conditions of geologic disasters,six independent indicators,namely,elevation,slope,relative elevation difference,engineering geological rock group,slope structure,and micro-geomorphic type,were selected to evaluate the susceptibility of landslides in the county by using the informativeness model,and the results were basically in line with the actual situation,and the results of the study can provide reference for the evaluation of the susceptibility of landslides in the similar areas.
