| 摘 要： | 基于遥感和地理信息系统技术,用空间主成分分析法构建评价指标体系,并用层次分析法确定评价指标权重,以滑坡危害最重的贵州省毕节地区为研究区,选取地层岩性、降水量、土地利用、坡度等9个滑坡孕险因子作为评价指标,对该研究区进行了滑坡灾害危险性评价。通过与研究区的历史滑坡灾害记录结果进行比较发现,评价结果与实际状况较为吻合,说明该方法能较有效地用于对区域滑坡灾害危险性的评价。

| Abstract: | Based on remote sensing(RS)data and geographic information system(GIS) software,landslide hazard evaluation for Bijie area,Guizhou Province was assessed by using spatial principal component analysis to establish evaluation indices and using analytic hierarchy process(AHP) to determine weights of evaluation indices.Nine factors were selected,such as formation lithologic character,precipitation,landuse type,slope grade and so on.The results are basically in agreement with actual conditions.This study method p... |
