摘要/Abstract

摘要： 为更好地援助和重建灾区,至关重要的一点就是对地震灾区采用科学有效的方法进行正确的综合评价.依据灾情指标基于加权TOPSIS法综合分析了汶川地震36个严重受灾县市的情况.首先,建立了基于主成分分析法和熵值法的两类加权TOPSIS法.然后,采用加权TOPSIS法分别对地震灾情数据进行分析得到36个严重受灾县市的相对接近程度综合评价值.最后,对36个县市按照灾情严重程度分别依据相对接近程度综合评价值进行了排序和分类.基于两类加权TOPSIS法所得结果与文献所得结果基本一致,因此加权TOPSIS法是正确进行地震灾情综合评价的有效方法.

Abstract: For the disaster area aid and reconstruction well, it is important to use the scientific and effective method to carry on the correctly comprehensive evaluation of the earthquake disaster area. According to the disaster index, 36 seriously affected counties of Wenchuan earthquake have been analyzed on weighted TOPSIS method. Firstly, two types of weighted TOPSIS method are established based on the principal component analysis method and entropy method. Secondly, these relative proximity comprehensive evaluation values of 36 counties and cities are obtained through analyzing the earthquake disaster data by two types of weighted TOPSIS method, respectively. Finally, according to the severity of the disaster, these 36 counties and cities are ranked and classified by these relative proximity comprehensive evaluation values. The results of two types of weighted TOPSIS method are consistent with the reference results, so these methods are the effective ways of the correctly comprehensive evaluation to the earthquake disaster.

Key words: Earthquake, Indicator Evaluation, Principal Component Analysis Method, Entropy Method, TOPSIS Method
