中文摘要：

以保山市隆阳区为研究区,选取滑坡、泥石流和不稳定斜坡3种典型地质灾害类型为对象,综合运用GIS技术与多种空间点模式分析方法对地质灾害的集聚特征进行定量分析,并划定其空间集聚热点区域.研究结果表明：隆阳区内滑坡、泥石流和不稳定斜坡灾害均呈显著的空间集聚特征,且集聚程度和规模随观测尺度的变化而变化;各地质灾害的空间集聚特征差异明显,形成了不同的空间集聚模式;不同地质灾害类型在空间热点分布上差异与共生现象并存.管理者在灾害治理工作中需采用区别治理与统一治理相结合的综合治理方案.

英文摘要：

By examining the spatial clustering characteristic of geological disaster and demarcating the corresponding spatial hot spot,we can provide important support for making sound decisions on geographical disaster prevention and allocation of disaster prevention resources. Taking Longyang district,Baoshan city as study area,landslide and debris flow,unstable slope of 3 kinds of typical geological disaster was selected as study targets,this article combine GIS technology with a variety of spatial point pattern analysis method to study on the spatial clustering characteristics and spatial hot spots of geological disasters. Conclusions are drawn as follows：Generally speaking,landslide and debris flow,unstable slope in study area are significantly agglomerated,and the agglomeration degree changing with the spatial scale; spatial agglomeration of each geological disaster presented different characteristics,different spatial clustering patterns was formed. From the perspective of spatial clustering hot spots,there are both symbiosis phenomenon and different hot spots among different geological disasters. Therefore,the manager department should make a comprehensive treatment plan which is combined differential treatment with comprehensive harnessing.
