鄂州市城区地质灾害易发区划分

摘要

阐述湖北省鄂州市城区地质灾害易发区划分方法。基于GIS技术在鄂州市城区地质环境条件分析、地质灾害详细调查的基础上，采用以定性分析为主、袭扰系数法为辅的方法对鄂州市城区进行地质灾害易发程度分区。结合地质灾害分布规律及形成机制，对各个分区进行详细评价，并提出相应的防治对策，为鄂州市城区地质灾害防治规划提供科学依据。%The authors introduce the region division of geological hazards prone areas in Ezhou urban,Hubei Province. Based on the analysis of geological environment conditions and detailed investigation of geological hazards in Ezhou urban by GIS technology,the subarea of easily produce geological disaster has been divided by means of qualitative analysis supporting by disturbance coefficient method. Combining with the distribution rules and formation mechanism of geolog-ical hazards,each subarea has been evaluated in detail and corresponding prevention countermeasures have been put for-ward,which provides a scientific basis for the geological hazard prevention planning of Ezhou urban.
