摘要
在吴堡县地质灾害野外调查的基础上,针对吴堡县地质灾害,选取坡度、坡高、坡型、坡向和斜坡地质结构类型作为评价指标,基于ArcGIS平台进行易发性评价。根据评价结果,可将吴堡县划分为极高易发区、高易发区、中易发区、低易发区和不易发区5个等级,分布面积分别为35.78km2、65.58km2、198.88km2、104.72km2、15.89km2,并结合野外调查数据对评级结果进行验证,准确度较好。其评价结果可以为吴堡县乡村建设提供科学的地质依据,减少地质灾害造成的人员和经济财产的损失。
Based on the field investigation of geological hazards in Wubao County,slope,slope height,slope type,slope orientation,and slope geological structure type were selected as evaluation indicators for the geological hazards in Wubao County.The susceptibility evaluation was conducted using the ArcGIS platform.According to the evaluation results,Wubao County can be divided into five levels:extremely high susceptibility area,high susceptibility area,medium susceptibility area,low susceptibility area,and low susceptibility area,with distribution areas of 35.78km2,65.58km2,198.88km2,104.72km2,and 15.89km2,respectively.The accuracy of the rating results is verified by combining field survey data.The evaluation results can provide scientific geological basis for rural construction in Wubao County,reducing the losses of personnel and economic property caused by geological disasters.
