摘要
从经济暴露性、经济敏感性和应灾恢复能力3个方面构建评价体系,选取15项指标,利用组合赋权法以及贡献度模型对西安地区地震灾害引发的经济脆弱性进行评价。结果显示:区域经济发展水平是影响西安地区地震灾害引发经济脆弱性的主要因素,地震灾害引发的经济脆弱性存在较大的空间差异,其脆弱程度与经济发展水平不完全一致;区域产业产值和产业结构决定了地震灾害引发的经济暴露程度与敏感程度,灾后恢复重建能力与区域财政收入、医疗卫生水平等因素密切相关;西安地区地震灾害引发的经济脆弱性准则层因子贡献度和指标层因子贡献度存在较大差异,主要因子对脆弱性贡献呈趋同态势。
This paper established the evaluation system from three aspects, the economic exposure, economic sensitivity and recovery ability of earthquake disaster, selecting 15 indexes , this paper evaluated the economic vulnerability caused by earthquake disasters of Xi＇an area through combination weighting method and contribution model. The results showed that regional economy development level is the main influencing factor of the economic vulnerability caused by earthquake disasters. The economic vulnerability caused by earthquake disasters have large space differences in xi＇an area, which is not completely consistent with the level of economic development. The regional industrial output value and industrial structure determine the degree of economic exposure and the degree of sensitivity, the reconstruction capability is closely related to the regional fiscal revenue and the medical level , etc. The economic vulnerability caused by earthquake disasters factor contribution of criterion layer and index layer has significant difference in xi＇an area, main factors contribution to vulnerability present convergence trend, contribution of criterion layer and index layer is a huge difference in xi ＇an area, main factor contribution to vulnerability was convergence trend.
