| 摘 要： | 以北京时间2013年4月20日8时02分四川省雅安市芦山县7.0级地震为例,对研究区进行震后次生滑坡灾害风险评价.研究在利用芦山地震受灾区航空影像对震后次生滑坡灾害隐患点解译的基础上,选择坡度、坡向、震后累计降雨量和危险植被指数4个评价因子,利用统计分级法对各因子进行敏感性分析,采用层次分析法（Analytic Hierarchy Process,AHP）对评价因子进行权重量化,最后综合运用GIS空间分析技术对芦山地震震后次生滑坡灾害进行风险评价,研究结果将研究区划分为次生滑坡灾害高危险区、中危险区和低危险区.

| Abstract: | Taking Lushan 7.0 earthquake on April 20th, 2013 at 8:02 as an example, we carried out earthquake secondary landslides hazard assessment. On the basis of the remote sensing of landslides after Lushan earthquake disaster through visual interpretation, we choose slope, aspect, cumulative rainfall and vegetation damage index as evaluation factors. The sensitivity of each factor is evaluated by statistical classification method. Analytic Hierarchy Process methods are applied to quantitative weights of evaluation factors. Finally, we integrated use of GIS spatial analysis technology to assess the hazard of the earthquake secondary landslides in Lushan. Based on our results, the study area was divided into three classes: extremely risk areas, moderately risk areas and minor risk areas. |
