摘　　要：基于2008年汶川地震灾情数据,应用灰色关联法对36个严重受灾县市依据8个灾情指标进行了综合分析。首先,采用灰色关联法分析得到了36个严重受灾县市的关联度评价值。然后,依据关联度评价值和其均值化数值按照灾情严重程度分别对36个县市进行了排序和分类。该研究的结果合理且符合实际,可以为汶川地震灾情综合评价提供理论依据。Based on the disaster data of Wenchuan earthquake in 2008 and 8 disaster indexes, the comprehensive analysis is conducted on 36 serious disaster-stricken counties and cities with grey correlation method. Firstly, these correlation degree evaluation values of 36 counties and cities are obtained through the analysis of grey correlation method. Secondly, according to the evaluation values and equalization values, these 36 counties and cities are ranked and classified in accordance with disaster severity. The study results are reasonable and practical, and can provide the theoretical basis for the disaster evaluation of Wenchuan earthquake.
