摘要
赣南地区地质环境条件复杂,人类工程活动尤其是切坡建房频繁,崩塌、滑坡等地质灾害频发。本文在对赣南重点城镇灾害地质详细调查基础上,根据研究区地质环境条件及地质灾害发育特征,选取10个地质灾害易发性评价指标,建立了评价指标体系。采用逻辑回归模型,结合ArcGIS软件对各因子权重值叠加分析,通过栅格重分类将研究区划分为较高易发区、中易发区、较低易发区和低易发区4类,为赣南地区地质灾害防治提供依据。
There are complex geological environment conditions, strong human engineering activities which result frequent collapse and landslides geological hazards in south of Jiangxi. Based on the geological survey and the development characteristics of geological disasters of the key towns, ten evaluation indexes of geological hazard susceptibility are selected. The logical regression model and the ArcGIS are used to divide the study area into four types, which provides some reference for the comprehensive prevention and treatment of geological disasters in south of Jiangxi.
