| 摘 要： | 在深入总结分析金坪子滑坡和利用GIS技术提取坡度等因子的基础上,采用层次分析法从金坪子滑坡的表面形态、滑坡内部条件和诱发因素中选取11个指标作为评价金坪子滑坡危险度的评价因子,根据典型地质灾害危险度评价模型对金坪子滑坡进行危险性评价,最终得出金坪子滑坡的危险性系数为3.87,危险度为Ⅲ级,危险性较高;同时利用GIS空间分析功能将AHP法得到的权重进行因子赋值并叠加计算,最终得到金坪子滑坡危险性分区图,其结果与实际勘察情况具有较好的一致性。结果表明,运用层次分析法和GIS技术相结合进行金坪子滑坡危险性评价是切实可行的。

| Abstract: | Based on detailed analysis of the Jinpingzi landslide,the AHP method,combined with GIS technology that can extract some factors from the landslide,is used to select 11 indicators from surface morphology,internal conditions and predisposing factors which are for the purpose of evaluating the risk of the Jinpingzi landslide.According to the typical geological disaster risk assessment model,the risk assessment for the Jinpingzi landslide hazard was carried out.This result showed that the risk coefficient of th... |
