摘要
采用模糊综合评判法,以MapGIS为工作平台,利用1∶100 000数字地形地质图,对陕西省重灾区勉县进行了地质灾害易发区划分,共将调查区划分为高、中、低和非易发4级9区,结果表明该方法划分的地质灾害易发区较为客观地反映了实际情况。
By adopting the fuzzy comprehensive evaluation methods, the paper taking MapGIS as the operation platform,makes use of 1∶100 000 digital terrain and geologic map,classifying the hazardprone areas of geological disasters of Mian county in Shanxi province into four levels,including high level,medium,low and no-disaster level,and nine zones,and it is shown by the result that the classifying hazardprone areas of geological disasters can reflect the factual situations objectively.
