摘要
利用2010—2019年江西省闪电定位监测数据、地理信息数据和社会经济数据,基于GIS技术、自然灾害风险评估方法和层次分析法等方法,从致灾因子、孕灾环境、承灾体3个方面,开展雷电灾害风险区划的研究,并形成江西省雷电灾害风险区划。结果表明:江西省雷电灾害的极高风险区和高风险区主要分布在南昌市、宜春市、新余市、上饶市、吉安市大部分地区和赣州小部分地区,中风险区和低风险区主要分布在九江市、萍乡市和抚州市大部分地区,该区划结果与江西省近10 a雷灾造成的人员伤亡情况大致吻合。
Based on GIS technology,natural disaster risk assessment method and analytic hierarchy process,the risk zoning of thunder and lightning disaster in Jiangxi were discussed by using the lightning location monitoring data of Jiangxi province from 2010 to 2019,geo-informational and socioeconomic data,considering the disaster-inducing factors,disaster pregnant environment and hazard-bearing bodies.The results showed that:the high-risk areas mainly located in the central part of northern and southern Jiangxi province,and the low-risk areas mainly located in the northern part of northern Jiangxi province,the central and southern part of Jiangxi province.The risk zoning results were in good agreement with the casualties caused by the lightning disasters in Jiangxi Province in recent ten years.
