依据自然灾害系统理论,综合考虑致灾因子和承灾体特征,提出台风灾害风险评价方法。在GIS环境下对中国沿海地区台风灾害危险性、脆弱性和风险进行分析评价。评价结果显示:海南省、上海市和广东省、福建省、浙江省的沿海区域台风灾害危险性较高;北京市、天津市、上海市和江苏省、山东省的大部分地区及广东省、福建省、浙江省、河北省的沿海区域承灾体脆弱性较高;海南省、上海市和广东省、福建省、浙江省的沿海区域台风灾害风险较高;而北京市、天津市以及河北省、辽宁省和山东省的大部分区域台风灾害风险较低。
The risk assessment method of typhoon disasters was proposed according to the nature disaster system theory and considering the characteristics of hazard factor and bearing body.And in the GIS environment the hazard,vulnerability and risk of typhoon disasters in China coastal area were assessed.The assessment result showed that the hazard of typhoon disaster is higher in Hainan Province,Shanghai and the coastal areas of Guangdong,Fujian,Zhejiang provinces.The vulnerability of bearing body is higher in Beijing,Tianjin,Shanghai,the most parts of Jiangsu,Shandong provinces,and the coastal areas of Guangdong,Fujian,Zhejiang,Hebei Provinces.The risk of typhoon disaster is higher in Hainan Province,Shanghai and the coastal areas of Guangdong,Fujian,Zhejiang provinces,while in Beijing,Tianjin and the the most parts of Hebei,Liaoning,Shandong provinces,it is lower the risk.
