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

An integrated assessment system for social vulnerability of natural disaster was developed with indices from 10 aspects of social structure. Multi-factor analysis was used to comprehensively assess provincial social vulnerability from 1991—2010, and to extensively analyze its spatio-temporal evolution. It was found that spatially the overall pattern of natural disaster social vulnerability in China is stable, with a high-west-low-east and gradient spatial distribution. Temporally the overall social vulnerability is decreasing, and the spatial-dependency is increasing. Population, social security, education, culture, medical service and infrastructure are the major factors influencing social vulnerability, while the influence of economic development and land use is less important. These results will help to support regional sustainable development and capacity building of disaster prevention and reduction.
