| 摘 要： | 以山西省西北部地质灾害较为典型的地区兴县为例,应用野外地质灾害调查所收集的资料,建立山西兴县地质灾害空间数据库系统,并在GIS软件平台上将调查结果数字化,得到兴县现状地质灾害分布图,再利用对已矢量化的图层以及灾害点文件的叠加得到兴县地质灾害易发分区图.将其分成地质灾害高易发区、中易发区、低易发区3个区,其中高易发区又可进一步划分成2个二级区.分区的结果还揭示了地质灾害空间分布特征及其与人类工程活动和地质环境背景的关系.

| Abstract: | Taking Xingxian county as the typical area with geologic disaster in northwest of Shanxi,on the basis of data gathered in field investigation of geologic disasters,a space database of geologic disasters of Xingxian county was established.The investigation results were made into digit on the GIS software platform,and then the distribution map of geologic hazards was obtained. Through pilling up the vectored chart layers and the files of geologic hazards points,the regionalization map of the geologic disaster occurrence of Xingxian country was formed,which there could be divided into 3 districts of high,middle and lower geologic disaster occurrence district.The high occurrence district could be divided into 2 grade districts.The result of the regionalization reveals the spatial distribution feature of geologic hazards and their relations with the human activities and geological environment. |
