摘要
江西省上饶市广丰区属于典型的山区城市,地质灾害频发且分布广泛,严重威胁人民的生命财产安全。本文根据广丰区地质灾害最新资料和野外调查情况,选取坡度、高程变异系数、地貌类型、工程地质岩组、断裂距离、河流距离、NDVI、道路距离8个指标构建评价体系,基于信息量模型和地理探测器,进行地质灾害易发性评价,并对评价结果的合理性和精确度进行检验,以期为当地政府制订有效防治措施提供参考依据。
Guangfeng District of Shangrao City,Jiangxi Province is a typical mountainous city.Geological disasters occur frequently and are widely distributed,which seriously threaten people′s life and property safety.In this paper,according to the latest geological disaster data and field survey in Guangfeng District,eight indexes including slope,elevation variation coefficient,geomorphic type,engineering geological rock group,fault distance,river distance,NDVI and road distance were selected to construct an evaluation system.Based on the information model and geographic detector,the susceptibility of geological disasters was evaluated.The rationality and accuracy of the evaluation results were tested,to provide reference for the local government to formulate effective prevention and control measures.
