| 摘 要： | 玉树"4·14"地震发生后,地质灾害发育密度明显递增。通过对研究区地质环境条件及地质灾害基本特征分析研究,选取了历史地质灾害发育程度、地形地貌、工程地质岩组、地质构造、水文条件、植被条件、降雨量、地震、人类工程活动等影响因素,建立了相应的地质灾害危险性评价指标体系,采用层次分析法,基于GIS技术平台,对玉树"4·14"地震震后地质灾害进行了易发程度划分。

| Abstract: | After the Yushu ＂4 ·14＂earthquake,geological disaster development density increasing. Through the study of the geological conditions and environmental analysis of the basic features of geological disasters,the extent of selected factors affecting the development of geological disasters in history,topography,engineering geological rock group,geological,hydrological conditions,vegetation conditions,rainfall,earthquakes,human engineering activities,a corresponding evaluation index system of geological hazard was established. Using AHP and GIS technology platform,the geological disasters prone to aftershock in Yushu were evaluated. |
