摘　　要：以秦岭北麓西安市临潼区仁宗街道为研究区,在野外调查、遥感解译的基础上,确定、分析了40处地质灾害隐患点的发育特征及其主要影响因素;基于DEM数据,构建了研究区663个斜坡单元地质灾害风险评估体系,通过地质灾害易发性、危险性和易损性分析,得到了考虑斜坡稳定性和承灾体危害性的仁宗街道斜坡单元地质灾害综合风险评估结果;通过野外实地验证,证实了评估结果的准确性和可靠性。据此划分了地质灾害防治区,从防灾减灾和工程建设两维度提出了仁宗街道的地质灾害风险防控措施建议,为研究区国土空间规划提供参考依据。Based on field survey and remote sensing interpretation,the development characteristics and disaster pregnant conditions of 40 potential geological hazard points are determined and analyzed in Renzong Street,Lintong District,Xi'an City,at the northern foothills of the Qinling Mountains as the study area.Based on DEM data,a geological hazard risk assessment system for 663 slope units in the study area is established.Through the analysis of the susceptibility,danger,and vulnerability of geological hazards,a comprehensive risk assessment result of geological hazards for slope units in Renzong Street is obtained,taking into account slope stability and the hazards of the disaster bearing body.The accuracy and reliability of the evaluation results have been confirmed through field verification.Based on this,geological disaster prevention and control areas are divided,and suggestions for geological disaster risk prevention and control measures in Renzong Street are proposed from two dimensions:disaster prevention and reduction,and engineering construction,providing a reference basis for the study area's land spatial planning.
