台风灾害影响下深圳市社会脆弱性评价与策略研究

Research on Social Vulnerability Evaluation and Corresponding Strategies in Shenzhen under the Influence of Typhoon Disasters

文章以深圳市为研究对象,从暴露度、敏感性和适应力三个维度构建台风灾害社会脆弱性评价体系,识别社会脆弱性不同等级区域的脆弱性成因。结果表明:①深圳市各区台风灾害社会脆弱性水平不一,存在较大差异。②深圳市不同等级的台风灾害社会脆弱性在空间上呈现出集聚分布特征,高社会脆弱性主要集中在沿海一带。③深圳市台风灾害高脆弱性成因差异显著,罗湖区、盐田区和大鹏新区分别以高敏感性致脆型、高暴露度致脆型和低适应力致脆型为主。本研究能够为政府开展城市防灾和韧性提升工程等方面提供相应的参考。

Taking Shenzhen City as the research object,this paper constructs a social vulnerability evaluation system under typhoon disaster from three dimensions:exposure,sensitivity and resilience.The causes of vulnerability in areas with different levels of social vulnerability are identified.The results show that:①The levels of social vulnerability to typhoon disasters in various districts of Shenzhen are different,and there are great differences.②The social vulnerability of different levels of typhoon disasters in Shenzhen presents the characteristics of agglomeration and distribution in space,and the high social vulnerability is mainly concentrated in the coastal area.③The causes of high vulnerability to typhoon disasters in Shenzhen are significantly different.Luohu District,Yantian District and Dapeng New District are dominated by high-sensitivity- induced brittleness, high-exposure-induced brittleness, and low- adaptability-induced brittleness, respectively. This research can provide references and suggestions for the government to carry out urban disaster prevention and resilience enhancement projects.
