摘要
利用江苏扬州市基础地理信息数据、2017—2020年社会经济数据及2001—2020年的逐日降水气象资料,运用层次分析法、加权综合评价法等方法,结合ArcGIS(地理信息系统软件)技术从孕灾环境敏感性、致灾因子危险性、承载体易损性、防灾抗灾能力4个方面选取指标,评价扬州市暴雨洪涝灾害风险水平并划分风险区域等级。评估结果显示:高风险区主要分布在扬州市北部,如降雨量丰沛的宝应县。低风险区主要分布在东南部。研究结果为扬州市暴雨洪涝灾害防御和风险管理提供了参考和借鉴。
Based on the basic geographic information data of Yangzhou City of Jiangsu Province,the socio-economic data from 2017 to 2020 and the daily precipitation meteorological data from 2001 to 2020,using the methods of analytic hierarchy process,weighted comprehensive evaluation method and ArcGIS(geographic information system software)technology,the indexes are selected from four aspects:the sensitivity of disaster trigger environment,the risk of disaster causing factors,the vulnerability of bearing body and the resilience ability of disaster,Evaluate the risk level of rainstorm and flood disaster in Yangzhou and classify the risk areas.The assessment results show that the high-risk areas are mainly distributed in the north of Yangzhou,such as Baoying county with abundant rainfall.Low risk areas are mainly distributed in the southeast.This provides reference information for Yangzhou to prevent rainstorm and flood disasters and do a good job in risk management.
