黑龙江省雷暴灾害损失风险评估与区划

Risk assessment and zoning of thunderstorm loss in Heilongjiang Province

利用黑龙江省2001-2005年78个气象站的雷暴资料,采用加权综合评价法和AHP决策分析法首次对黑龙江省雷暴灾害损失风险进行了评估,并与GIS技术耦合进行了雷暴灾害损失风险区划。结果表明:雷暴灾害高损失风险区分布在哈尔滨、绥化及双鸭山的市区,危险性和暴露性因子为主导因子;中等损失风险区集中在哈尔滨以及绥化所辖的大部分县市,还有牡丹江、鸡西、大兴安岭地区的部分县市,以及齐齐哈尔市、黑河市和讷河县等地;轻、低损失风险区分布在齐齐哈尔、黑河的大部分县市及东部平原地区。

This paper conducts risk assessment and zoning of the thunderstorm disaster risk loss by using WCA,AHP and GIS technology,based on the thunderstorm data of 78 meteorological stations in Heilongjiang Province from 1971 to 2005.The research results show that high risk loss regions of thunderstorm distribute in Harbin,Suihua and Shuangyashan cities,the danger and exposure elements are the leading elements;the middle level risk loss regions locate in most counties under jurisdiction of Harbin,Suihua,and in some parts of Mudanjiang,Jixi,Daxinganling,Qiqihar,Heihe cities and Nehe County;the low risk loss regions distribute in most parts of counties under jurisdiction of Qiqihar,Heihe cities and in eastern plain.
