摘要: 为揭示区域社会易损性对地震灾害造成的损失的影响,以芦山和鲁甸地震灾区为研究区,根据统计资料和实地考察结果,构建包括10个指标的社会易损性评价指标体系,并利用熵值法综合评判2震区的社会易损性,进而证明震区社会易损性与地震灾害损失的因果关系。结果表明,低震级、波及范围小的鲁甸地震死亡人数大于高震级、波及范围大的芦山地震死亡人数,其原因之一是鲁甸地震灾区的社会易损性大于芦山地震灾区的。

Abstract: In order to reveal the effect of regional social vulnerability on the losses caused by the earthquakes, Lushan earthquake stricken area and Ludian earthquake stricken area were selected as the study object. Based on the statistical data and field investigations, an evaluation indicator system of social vulnerability was established. Using the entropy value method, the social vulnerability of Lushan earthquake stricken area and that of Ludian earthquake stricken area were comprehensively evaluated. The results showed that the social vulnerability of Ludian earthquake-stricken area was greater than that of Lushan earthquake-stricken area, and that one of the reasons why the small magnitude of Ludian earthquake causedHeavier casualties was the greater regional social vulnerability.

Key words: social vulnerability, comparative analysis, entropy method, Lushan earthquake, Ludian earthquake
