摘要
鄂州市处于长江中游经济带发展战略位置,区内地质环境条件脆弱,地质灾害易发,给当地社会发展带来了重大影响。通过调查和利用GIS进行地质灾害易发性空间分析,鄂州市地质灾害主要受地形地貌、地层岩性及人类工程活动等因素的影响,地质灾害在空间上整体呈东南多,西北少分布,局部上在强烈人类工程活动带易发,沿交通路线集中发育,矿集区最为显著,丘陵区集中分布,软弱和硬脆性岩层中易发。这成为未来地质灾害重要形成区,在后续的地质灾害防治规划中,应重点加强防范。
Ezhou is located in the middle reaches of Yangtze River economic zone where the vulnerable geological environment conditions and geological disaster development cause great influence to local society development.According to space analysis on geological disaster susceptibility with surveys and GIS,geological disaster in Ezhou is mainly controlled by topography and geomorphology,rock and soil property and affected by such factors as human engineering activities.The geological disaster is distributed more in southeast and less in northwest.Locally,the geological disaster susceptibility is in strong human engineering activities area,and along the traffic road,the most the concentrating area of mine.It is concentrated distributed in hills and weak and hard brittle rock area.Thus,this is important development area of geological disaster in future,afterwards which is deserved to focus on strengthening prevention for the control plan of geological disaster.
