| 摘 要： | 岩溶塌陷是我国主要的地质灾害，其易发程度的评估预测对减少社会损失有重要意义。以岩溶地貌发育的广西来宾市吉利村为研究实例，应用模糊层次分析法，结合研究区地质状况，引入G1S和遥感技术，对研究区的岩溶塌陷易发程度进行评估。首先确定岩溶塌陷评估因子及其权重值；其次划分塌陷等级，将其分为极易发区、易发区、一般区、较稳定区和稳定区；最后对研究区进行评估预测，对评估结果处理后得出研究区岩溶塌陷易发程度分区图。

| Abstract: | Karst collapse is the main geological disaster in our country, and the evaluation of its susceptibility has important significance to reducing the social loss. Lai bin, Jili of Guangxi is taken as an example to evaluate the geo-haz- ard susceptibility zones of Karst collapse. FAHP, which combines GIS and remote sensing technology with the geological conditions ,is used to determine the susceptibility of Karst collapse. First of all, it should determine the evaluation factors of Karst collapses and their weights. Then, the study area is divided into 5 collapse level： extremely prone area, basic prone area, general area, basic stable area, extremely stable area. At last, it gets the zoning evaluation map of geo-hazard susceptibility of karst collapse which through evaluate the study area and deal with the evaluation results. |
