摘要
在分析灾情评估指标特征的基础上,提出了一种适用于多指标的灾情评估普适公式;对不同的评估指标及其分级标准,用免疫进化算法对公式中参数进行优化,得到对不同灾情评估指标及评价标准适用的指数公式。公式用于我国部分省市和地区的多种自然灾害的灾度评价,评价结果比较符合实际。该公式具有可比性、普适性和简单实用的特点。
Based on the analysis of index character of disaster evaluation, a universal formula was presented for disaster evaluation that is suitable to different disaster indexes. To different evaluation indexes and its classification standard, the parameters in formulae were optimized by using the immune evolutionary algorithms. The different disaster evaluation indexes and applicable index formula of classification standard were obtained. The formula has been used in the disaster degree evaluation of varied nature disaster in some provinces, cities and regions of China, and its evaluation result conform with the actual situation. The formulae have the peculiarities of comparison, generality, simplicity and utility.
