以重庆市巴南区接龙镇为研究对象，在山洪灾害孕灾环境研究基础上，选取孕灾环境、汇流累积量、暴雨强度和河网密度4个指标，构建了山洪灾害危险评价指标体系，通过层次分析法确定指标权重，采用加权综合评价法构建山洪灾害危险评价模型，基于山洪灾害风险度评价技术与G IS技术，计算得到接龙镇山洪灾害危险综合指数，并对接龙镇山洪灾害危险进行综合等级划分绘制出了山洪灾害危险分区图。结果表明：接龙镇山洪灾害危险综合指数值位于8～69之间，全镇主要处于中等危险区，占总面积的80．53％；高危险区和低危险区分别占1．43％和18．04％，未出现极高危险区。

Taking Jielong Town in Banan District of Chongqing City as study object ,and on the basis of the integrated zoning of developing hazards of mountain torrent disaster research ,this article selects four indicators including hazard developing environment , flow accumulation , storm intensity and drainage density to construct evaluation index system of mountain torrent disaster risk .And then it determines the index weights by analytic hierarchy process (AHP) ,and uses weighted comprehensive evaluation method to construct mountain torrent disaster risk evaluation model .Supported by the mountain torrent disaster risk evaluation technology and GIS technology , the article calculates the mountain torrent disaster risk index in Jielong Town .And then it divides the mountain torrent disaster risk into several zones according to the risk index ,and draws the integrated zoning map of mountain torrent disaster risk in Jielong Town .The results show that the comprehensive index of mountain torrent disaster risk ranges from 8 to 69 ;the whole town is mainly distributed in middle -risk areas ,accounting for 80 .53% of the total area ;high-risk areas and low -risk areas respectively account for 1 .43% and 18 .04% ,and very high-risk areas do not appear .
