中文摘要：

为探索重庆市地质灾害孕灾环境分布情况,以重庆市主要地质灾害为研究对象,在分析孕灾因子基础上,选取暴雨强度、地貌条件、地质岩性、年均降雨量、植被覆盖度和地质构造条件等6个因子,构建地质灾害孕灾环境分区指标体系,利用层次分析法（AHP）和专家效度相耦合方法确定各指标权重,并建立孕灾环境综合指数评价模型。在ArcGIS软件平台支持下,以1 km×1 km网格尺寸为单位精细获取各指标分析数据,计算得到各网格孕灾环境综合指数值,并根据该值进行重庆市地质灾害孕灾环境等级区划分。结果表明：重庆市地质灾害孕灾环境综合指数值在43～84之间,孕灾分区主要集中在高易发区和中易发区,其中危险区1.29×104 km2,占总面积的15.62%;高易发区4.42×104 km2,占53.68%;中易发区2.38×104 km2,占28.85%;低易发区0.15×104 km2,占1.85%。

英文摘要：

Taking geological disaster in Chongqing as a case study,6 factors including rainstorm,geomorphological conditions,geological lithology,average annual rainfall,vegetation coverage and geological-tectonic conditions in Chongqing were selected to construct the index system of environment zoning of hazards developing.The index weight was obtained through the combination of AHP and expert reliability,and the comprehensive index evaluation model for hazards developing environment was built.Supported by ArcGIS,comprehensive index for hazards developing environment in each grid was calculated by the analysis data of each index precisely obtained through 1 km×1 km grids,then hazard developing environment of geological disaster in Chongqing was divided into different zones according to comprehensive index.The results show that Chongqing has sufficient environment conditions for geological disaster,its comprehensive index of hazards developing environment ranges from 43 to 84,and the hazards inducing environment zones are mainly distributed in high easy-happening area and medium easy-happening area,among which dangerous area,high easy-happening area,medium easy-happening area and low easy-happening area cover 12 900 km2,44 200 km2,23 800 km2,1 500 km2 respectively,and each accounts for 15.62%,53.68%,28.85%,1.85% of the total area.
