摘　　要：为研究龙卷风对我国各地的灾害影响,通过收集我国龙卷风灾情统计资料,建立了龙卷风灾害风险层次分析结构模型,开展了龙卷风灾害风险的区域划分研究。研究结果表明,夏季为我国龙卷风的高发期,全年约2/3龙卷风灾害发生在6~8月,发生在春季的龙卷风灾害约占总次数的1/3;我国龙卷风灾害发生的频率较高的地区是江苏省和广东省,其次是黑龙江省、山东省、内蒙古自治区和安徽省,统计期内上述省份的龙卷风发生次数之和超过龙卷风发生总次数的61.2%;根据龙卷风灾害风险度结果可将全国划分成龙卷风灾害四个等级风险区,其中最高风险区分布在华东地区,较高风险区分布在华中和华南地区。In order to study the impact of tornado disasters in China,by collecting statistics on the disasters of tornados,the hierarchical analysis structure model of tornado disaster risks was established,and the risk zoning of tornado disaster was developed.The research results show that,summer is the period of high incidence of tornadoes,about 2/3 of tornado disasters occur in June to August and about 1/3 occur in spring.The areas with higher frequency of tornado disasters in China are Jiangsu and Guangdong provinces,followed by Heilongjiang,Shandong,Inner Mongolia and Anhui provinces.The total number of tornadoes in these provinces during the statistical period exceeded 61.2%of the total number of tornadoes.According to the zoning results of tornado disaster risk,it can be divided into four levels of tornado disaster risk areas.The highest risk areas are located in East China,and the higher risk areas include Central China and South China.
