中文摘要: 选取落雷密度、雷灾发生率、雷灾经济损失率及雷灾生命损伤率为评价雷电灾害易损性的指标，运用解析几何的直线方程对指标数据进行了标准化，引入层次分析法对评价指标数据真实性程度对结果的影响进行了修正，采用聚类分析方法对总易损度值进行更为合理科学的区划分级，并以福建省为例对新模型做了实例计算。结果表明，综合评价算法模型在关系计算、级别区划、结果分析等方面体现出一定的数学优势，能较细致、完整地反映出雷灾易损度区划指标之间的联系及各指标因素对雷灾易损度的综合影响关系。

Abstract:Taking lightning density, incidence of lightning disaster, lightning disaster economic loss rate and the rate of lightning disaster damage as the lightning vulnerability assessment indices, we employed the analytic geometry of linear equation to standardize data and the AHP anlysis method to modify the index data, and finally utilized the cluster analysis to the total value of the vulnerability for a more rational and scientific classification, with Fujian Province as an example for the new model. The results show that the composite evaluation of model calculations is much better mathematically than other methods, and this method can detailedly and completely represent the relation between indices of lightning disaster vulnerability zoning and the combined effects of indices on lightning disaster vulnerability.
