| 摘 要： | 地震次生崩滑是震后较长时间内严重危害人们生活的地质灾害之一, 对其展开危险性评价具有重要意义。 本文选取2008年汶川地震的重灾区汶川县为研究区, 基于遥感数据, 利用GIS技术手段, 结合研究区地质环境背景进行地震次生崩滑危险性评价。 选取逻辑回归模型, 将研究区划分为不危险、 轻微危险、 较危险、 危险和极危险5个等级, 实现了基于Logistic模型的区域内地震次生崩滑地质环境危险性评价。

| Abstract: | Earthquake-induced collapses and slides are one of the geological disasters that can seriously endanger human life after earthquakes. In this article we select as study area the heavily devastated area Wenchuan county in the 2008 Wenchuan earthquake. Risk assessment of earthquake-induced collapses and slides is based on remote sensing data and GIS method, combined with the geological environment background of the study area. Logistic regression model was selected and the study area is ultimately categorized into five classes, namely, not dangerous, slightly dangerous, dangerous, more dangerous, extremely dangerous. |
