面对日益严峻的气候变化形势,开展区域社会脆弱性的研究有利于更好地应对极端气候事件及相关灾害.为研究长江中下游地区社会脆弱性的空间分布及其社会经济文化驱动因素,参考SoVI模型的指标体系选取36个指标对我国长江中下游的65个研究单元进行评价,采用因子分析法得到社会脆弱性的7个主要影响因子,据此得到最终的社会脆弱性指数及其分布.结果表明:长江中下游各地社会脆弱性差异明显,总体上呈现西高东低的态势.%In the face of increasingly severe climate changes, study of regional social vulnerability is conducive to better coping with extreme weather events and associated hazards. To quantify regional social vulnerability to natural hazards in the middle-lower reaches of the Yangtze River, and investigate the economic and cultural drivers, we referred to the SoVI model and index system and selected 36 variables for each of the 65 analysis units in the study area. Using factor analysis, seven main factors constituting social vulnerabili-ty were identified. The final social vulnerability index was calculated combining the seven main factors and the spatial distribution was mapped. The results show that the social vulnerability in the area obviously varies from west to east. The eastern developed regions and the capital cities of all the provinces are characterized with low vulnerability, while the high vulnerable areas are mainly concentrated in the central and western parts, especially the mountainous areas and minority autonomous prefectures.
