基于信息量模型的厦门市崩塌和滑坡地质灾害易发性评价
|
摘要
地质灾害易发性评价是地质灾害危险性评价与风险性评价的基础,是地质灾害调查研究的重点内容,其结果可以有效地指导地方政府的防灾减灾工作。厦门市地质灾害的类型主要为崩塌和滑坡,根据其发育特征,选取地形坡度、地面高程、地质构造、工程地质岩组、年平均降雨量、土地利用与人类活动、道路7大影响因素作为研究区崩塌和滑坡地质灾害易发性评价的评价因子,采用信息量法并结合GIS技术对厦门市崩塌和滑坡地质灾害的易发性进行评价。结果表明:评价结果与实际情况相吻合,可为厦门市地质灾害的防治提供依据。
Susceptibility evaluation of geological hazards is the basis of geological hazard risk evaluation and risk evaluation,and is the key content of geological hazard investigation and research,whose results can effectively guide local government's disaster prevention and mitigation work.The main types of geological hazards in Xiamen City are landslides and collapses.According to the development features of collapse and landslide in Xiamen City,this paper selected seven major factors as evaluation factors of collapse and landslide susceptibility,including topographic gradient,ground elevation,geological structure,engineering geological rock formations,annual average rainfall,land use and human activities,and roads.The information method was used to evaluate the susceptibility of collapse and landslide in Xiamen City.The results show that the evaluation results are consistent with the actual situation and can provide a scientific basis for the prevention and control of geological hazards in Xiamen City.
