本文以RS和GIS为技术手段,通过遥感影像目视解译和野外验证对研究区地面塌陷地质灾害点进行统计。在此基础上,结合研究区的地质背景和收集到的相关资料,分析了研究区地面塌陷地质灾害的发生机理,选取合理的地面塌陷危险性评价指标因子,基于层次分析方法建立了地质灾害危险性评价的指标体系,对研究区进行了危险性评价,取得了较好的评价结果。
In this paper, RS and GIS are the technical means to make statistics on the geological disasters caused by ground subsidence in the study area through visual interpretation of remote sensing images and field verification. On this basis, combined with the geological background of the study area and the relevant data collected, the paper analyzes the mechanism of geological disasters in the ground subsidence area in the study area, selects the reasonable evaluation index factors of danger of ground subsidence, and establishes the risk of geological disasters based on AHP The index system of sexual evaluation, carried on the dangerous evaluation to the study area, obtained the better evaluation result.
