中文摘要: 汶川“5·12”特大地震发生后,成都市的都江堰等5个市县遭受了不同程度的破坏,地质灾害是震后对生态系统和社会经济系统造成威胁的方式。易损性区划不仅反映灾区的生态系统,社会经济系统对地质灾害的敏感性,而且可以划分出对灾害最敏感的区域和承灾体,为灾后的重建规划提供依据。采用贡献权重迭加模型对5个市县进行评价,评价指标包括自然资源环境、社会经济和地质灾害。结果表明,高易损度区、中易损度区、低易损度区分别占5个地区总面积的19.3%、22.64%、58.04%,并且根据评价结果,对灾区易损原因进行了分析。
Abstract:After Wenchuan earthquake, Dujiangyan、Pengzhou、Dayi、Chongzhou、Qionglai ,which are belonged to Chengdu ,suffered varying degrees of damage and are the most serious areas.Geological disasters are the most primary styles which threaten the ecosystem and socio economic systems. Division reflects not zoning of vulnerability reflect sensitivity of ecosystem and socio economic systems to geological disasters and can be carved out preparedness and post-disaster reconstruction planning. Contributing weight approach is employed to zoning vulnerability degree. Index including environment, socio economy and geological disasters. outcome showed that areas of high vulnerability, middle vulnerability and low Vulnerability is corresponding to 19.32%, 22.64%, 58.04% of study area, respectively. Then causes of vulnerability are analyzed through outcome.
