我国沿海地区近54a台风灾害风险特征分析

FEATURES OF TYPHOON IN SOUTHEAST COASTAL REGIONS OF CHINA IN THE RECENT 54 YEARS

台风严重影响着我国东南沿海省市的社会经济发展,本文选取南方沿海八个省市为研究区,利用1949—2002年共54 a登陆台风次数和1985—2002年的18 a经济损失的数据库信息,结合社会经济条件,对比分析了研究区台风易损性,及登陆台风的年内分布特征。探讨登陆台风的规律性及研究区台风易损性,将有利于合理部署救灾工作,合理分配救灾资源,并为社会减灾工作,尤其是长期的救灾规划提供指导作用。

Southeast regions in China are affected heavily by typhoon disaster; eight southeast coastal regions were selected to analyse contrastively features of landing typhoon including monthly distribution during the year and potential vulnerability using population density and per capita GDP. Contrastive comparisons among those eight regions were emphasized to look for similarities and differences. Studying rules about typhoon landing in China and comparison among selected study areas make sense for putting guidance for storage of relief materials and for disaster prevention and relief, and make sense for making relief plans.
