Abstract广东省是我国的经济大省,频繁遭受台风侵袭,造成巨大的经济损失,进行区域台风灾害经济损失风险的定量评估在制定防灾减灾措施方面具有重要的理论意义。本文通过1954-2008年间全国台风灾情数据与台风强度等级构建直接经济损失率曲线,采用GIS空间分析方法,计算广东全省98个县域单元不同强度等级台风经济脆弱性,在计算不同强度等级台风登陆广东的频次基础上,确定不同强度等级台风发生可能性,最终采用风险评估模型,对不同强度等级台风造成的广东省经济损失风险进行定量评估。评估结果表明:广东台风灾害造成的经济损失风险在百亿元以上,微度、轻度、中度和重度分别达到104.67、144.29、77.53和135.91亿元。空间上表现为珠三角地区的广州市、东莞市、深圳市、中山市、珠海市风险最高,从珠江入海口地区向内地呈辐射状减弱,内陆远离海岸线的县市风险值最低,不足0.50亿元,随着台风强度由微度到中度增强,粤西风险高于粤东,当达到重度时,表现为粤东沿海高于粤西沿海的格局。
