摘要

将美国社会脆弱性指数(SoVI)方法用于中国沿海地区,并基于中国国情进行改进,以探索中国沿海地区社会脆弱性的空间分布及其社会经济文化驱动因素.基于SoVI方法,选取31个指标对我国沿海的300个研究单元进行评价,采用主成分分析法得到社会脆弱性的6个主要影响因子:城镇化水平,经济条件,年龄与性别,民族与特需人群,居住条件与文盲,医疗水平.对这些因子按照对社会脆弱性的正向或负向作用进行加和,得到最终的社会脆弱性指数.结果显示,最高的社会脆弱性集中在海南省及北部湾沿岸,江苏北岸和辽宁省北岸社会脆弱性也较高.

Abstract

Coastal areas are significant for a country's economic development, but are usually prone to natural disasters. This article presents a study on the social vulnerability of the coastal area in China by application of the place-based social vulnerability index (SoVI) developed for the United States to explore the causes and drivers of social vulnerability. Thirty-one variables adapted from SoVI were collected for each of the 300 analysis units in the study area. Using principal components analysis, six factors were identified from the variable set: urbanization, economic status, age and gender, race and special needs population, living conditions and illiteracy rate, medical services. Factor scores were summed to obtain final SoVI scores and the most and least vulnerable study units were identified and mapped. The highest social vulnerability is concentrated in the coastal area of Beibuwan and Hainan province, in northern Bohai coastal area, Jiangsu coastal area, and some part of coastal areas in Guangdong.
