摘要
为了评估台风的灾害影响程度,本文分析了1971-2012年影响江西的台风灾害特征,引入了属性层次模型(AHM),基于风、雨、气旋等气象因素计算综合影响指数,对1971-2012年影响江西的台风进行了灾害评估。另外,综合考虑风雨因素和承灾体的易损性,建立单个台风的灾害分布评估模型,对单个台风在不同区域的影响进行评估。对比灾情损失来看,此评估模型可以为开展防台减灾和灾后重建提供定量、定点的参考数据。
In order to evaluate influencing degree of typhoon disasters,the disaster characteristics of 80 tropical cyclones influencing Jiangxi Prvince from 1971 to 2012 were analyzed firstly.Then the attribute hierarchical model(AHM) was applied in evaluating the tropical cyclone disaster's influence based on meteorological data.Combining with the potential vulnerability,the synthetical tropical cyclone influencing index of single tropical cyclone also could be acquired through the AHM,which could be given to the government as a reference,and could be taken to assess the factual effect on defending and decreasing disaster.
