摘　　要：采用信息量模型和层次分析法,对镇江丹徒区进行孕灾地质条件分析,选取地形起伏度、坡度、工程地质岩组、地质构造、高程、灾点密度6个评价因子构建评价体系,计算镇江丹徒区内滑坡崩塌地质灾害易发性加权信息量值,将该区域地质灾害划分为高易发、中易发、低易发3个等级。计算结果与实际调查结果相吻合。评价方法为该地区地质灾害风险性评价提供了科学客观的基础数据。In this paper,the information content model and analytic hierarchy process are used to analyze the disaster-prone geological conditions in Dantu District of Zhenjiang.Six evaluation factors,including topographic relief,slope,engineering geological rock formation,geological structure,elevation and disaster point density,are selected to construct the evaluation system.By calculating the weighted information value of landslide and collapse geological disasters in Dantu District of Zhenjiang,the regional geological disasters are divided into three levels of high,medium and low susceptibility.The calculated results are in agreement with the actual survey results.This method provides scientific and objective basic data for geological hazard risk assessment in this region.
