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、常州和连云港为低易损区
在分析江囌省龍捲風氣候特徵的基礎上,利用主成分分析方法對江囌省龍捲風災害易損性進行瞭綜閤評估,得到瞭江囌省各市的龍捲風災害易損度,併利用聚類分析對各市易損度進行瞭分級區劃.錶明徐州為龍捲風災害極高易損區,泰州、南通、囌州為高易損區,鹽城、鎮江、颺州為中易損區,淮安、宿遷、南京、無錫、常州和連雲港為低易損區

Based on analysis of tornado climate characteristic in Jiangsu Province, the overall assessment of Jiangsu Province tornado disaster vulnerability has carried out by the principal components analysis method. 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.
