摘要 为了提高广西台风防减灾业务的时效性和精准度,基于自然灾害风险评估理论和方法,根据2010年广西生态遥感本底数据和社会经济空间化数据、地理信息数据,构建耦合自然生态和社会经济的台风灾害承灾体脆弱性指标体系,运用基于GIS的风险指数法,建立台风灾害承灾体脆弱性评价模型,实现了像元尺度的广西台风灾害承灾体脆弱性精细化评价。结果表明: 广西台风灾害承灾体高脆弱区域主要分布在桂南、桂东南高暴露于台风灾害的建设用地和生态易损农用地、水土流失严重的裸地,占全区面积的25.9%;低脆弱区主要分布在桂东、桂东北、桂西北、桂西社会经济落后和植被覆盖度较高的山区,占全区面积的45.6%。

Abstract: In order to improve the timeliness and accuracy of typhoon prevention and mitigation operations in Guangxi, using ecological remote sensing background data, socio-economic spatial data and geographic information data in Guangxi in 2010, we have established a vulnerability evaluation index series for the hazard bearing bodies of typhoon disaster by coupling natural ecosystem and society economy based on the natural disaster risk assessment theory and methods. Then we have designed an appropriate evaluation model based on GIS, and accomplished the elaborate evaluation of typhoon disaster vulnerability for the hazard bearing bodies in Guangxi with a cell scale. The results show that most of the high vulnerability areas of typhoon-hazard bearing bodies are located in the southern and southeastern of Guangxi, occupying 25.9% of the Autonomous Region, where are mostly construction land of high exposure to typhoon, farmland of ecological vulnerability and bare land of serious soil erosion. Most of the low vulnerability areas are found in the eastern, northeastern, northwestern and western region of Guangxi, accounting for 45.6% of the Autonomous Region, where are mostly mountain areas with backward social economy and relatively high vegetation coverage.
