摘要
选取2022年广西“龙舟水”期间6月17-21日暴雨过程,基于91个国家气象观测站和2800个区域自动气象站资料、地理信息、暴雨灾情及其他社会经济资料,从危险性、暴露度和脆弱性三个维度开展精细化暴雨灾害风险评估。结果表明:(1)此次过程的风险评估结果与致灾危险性的空间分布基本一致,桂东北地区高、其他地区低,暴雨致灾危险性在对风险评估结果的贡献中占主导地位;(2)桂林、柳州两市大部及河池、贺州、来宾、贵港、梧州、钦州部分县(市、区)的暴雨致灾危险性及人口、GDP、水稻风险等级相对较高;(3)暴雨灾害风险评估结果反映的高风险和需要重点防御的区域,与实际受灾区域基本相符。
Based on the 91 national meteorological observation stations and 2800 regional automatic meteorological stations,geographic information,rainstorm disasters and other socio-economic information,the heavy rainfall process from June 17 to 21 during the dragon-boat rainy season in Guangxi in 2022 was selected to carry out refined rainstorm disaster risk assessment from three dimensions of hazard,exposure and vulnerability.The results show that:(1)the risk assessment results of this process are consistent with the spatial distribution of disaster risk,which are high in northeastern Guangxi and low in other areas in Guangxi,and the rainstorm hazards dominate the contribution to the risk assessment results;(2)the storm disaster-causing hazards and the population,GDP,and rice risk levels in most areas of Guilin and Liuzhou cities and some counties(cities or districts)in Hechi,Hezhou,Laibin,Guigang,Wuzhou and Qinzhou are relatively high;(3)the high-risk areas and areas requiring key defense as reflected in the results of the storm disaster risk assessment are consistent with the actual disaster-affected areas.
