基于Logistic模型的地震次生崩滑危险性评价以汶川县为例

Abstract

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.

Key words: Risk assessment, Earthquake-induced collapse and slide, Logistical model, the 2008 Wenchuan earthquake
