【摘要】：基于社会脆弱性的理论内涵,本文综合考虑社会结构的10个方面影响,构建中国社会脆弱性综合评价指标体系,利用多元因子分析方法(MFA),对1991—2010年省域社会脆弱性进行综合评价,分析其时空演变.结果表明:从空间上看,中国自然灾害社会脆弱性格局较稳定,呈西高东低、梯度递减的分布规律;从时间上看,社会脆弱性总体呈下降趋势,空间依赖程度呈增长趋势;从影响因素上看,人口、社会保障、教育水平和社会文化、社会医疗及基础设施影响较显著,经济水平、土地利用状况影响相对次要,应对和适应能力的提升能有效降低区域社会脆弱性.该研究为区域防灾减灾能力建设与可持续发展提供了理论参考.
[Abstract]:Based on the theoretical connotation of social vulnerability, this paper comprehensively considers 10 aspects of social structure, constructs a comprehensive evaluation index system of social vulnerability in China, and makes a comprehensive evaluation of social vulnerability in the province from 1991 to 2010 by using the method of multiple factor analysis (MFAA). The results show that the pattern of social vulnerability to natural disasters in China is relatively stable in space, with the distribution pattern of high and low in the west and the east in the west, and the gradient decreasing, and the social vulnerability in general shows a downward trend in time. From the perspective of influence factors, population, social security, educational level and social culture, social medical treatment and infrastructure have significant effects, while economic level and land use status are relatively secondary. The improvement of coping and adaptive ability can effectively reduce the vulnerability of regional society. This study provides a theoretical reference for regional disaster prevention and mitigation capacity-building and sustainable development.
