摘要
在分析江苏省龙卷风气候特征的基础上,利用主成分分析方法对江苏省龙卷风灾害易损性进行了综合评估,得到了江苏省各市的龙卷风灾害易损度,并利用聚类分析对各市易损度进行了分级区划。表明徐州为龙卷风灾害极高易损区,泰州、南通、苏州为高易损区,盐城、镇江、扬州为中易损区,淮安、宿迁、南京、无锡。
Based on analysis of tornado climate characteristic in Jiangsu Province, the overall assessment of Jiangsu Province tomado disaster vulnerability has carried out by the principal components analysis method. Jiangsu each city＇s tornado disaster vulnerability is obtained, and the graduation regionalization of each city＇s vulnerability has carried out by the cluster analysis. The results show that Xuzhou belongs to the maximal damageable area. Taizhou, Nantong, Suzhou belong to the high damageable area. Yancheng, Zhengjiang, Yangzhou belong to the medium damageable area. The rest cities belong to the low damageable area.
