基于ArcGIS的当涂县地质灾害风险调查与评价

地质灾害风险调查评价是防范地质灾害、降低风险的一种重要方法。通过 ArcGIS 软

件，采用定量分析和统计评价模型相结合的方法，进行当涂县全境地质灾害的易发性、危险性和易损

性评价，并据此进行地质灾害风险评估。调查及评价结果显示，当涂县全境可划分为地质灾害中风

险、低风险和无风险区，其面积分别占全县面积的1.40%、2.27%和96.33%；当涂县地质灾害中风险区

主要分布于白纻山和大青山南部中高丘区域内。本次评价成果可为地区地质灾害防治和风险预测、

国土空间规划以及城市建设等领域提供技术支撑。

Geological disaster risk investigation and evaluation is an important method to prevent geo⁃

logical disasters and reduce risks.Through the combination of quantitative analysis and statistical evaluation

model by ArcGIS software，the susceptibility，risk and vulnerability of geological disasters in Dangtu Coun⁃

ty were evaluated，and the risk assessment of geological disasters was carried out accordingly.The survey

and evaluation results show that Dangtu County can be divided into risk，low risk and risk-free areas of geo⁃

logical disasters，which account for 1.40%，2.27% and 96.33% of whole county area respectively.The risk

areas of geological disasters in Dangtu County are mainly distributed in the middle and high hilly areas of

Baizhu Mountain and the south of Daqing Mountain.The evaluation results can provide technical support for

regional geological disaster prevention and risk prediction，land space planning and urban construction.
