对台风灾情评估提出了一种基于台风灾害案例历史案例分析、综合模糊数学和灰色关联分析的综合评估模型；利用模糊隶属函数将台风灾情原始数据无量纲化,再设定一极重灾为参考序列.根据台风各评估指标与参考序列的距离,计算出关联系数；将关联系数加权平均和定义为灾度,根据灾度值评定台风的灾级.并以广东省台风灾情为例,验证了此模型.%Based on the case study, comprehensive fuzzy mathematical analysis and grey relational analysis of historical typhoon cases, a model for comprehensive evaluation of typhoon disasters is worked out. In this model, the typhoon disaster raw data are processed with dimensionless method by use of fuzzy membership function, and a severely affected area is set as the reference series. The correlation coefficients are calculated according to the distance between the typhoon evaluation index and the reference series. Then, the correlation coefficients are processed by weighted average and defined as disaster degree. The disaster grade of typhoon is evaluated based on the disaster degree. Taking typhoon disasters in Guangdong province, the model is verified.
