摘    要:考虑气象数据的特点和灾后评估的时效性,针对暴雨灾害的平均降水强度、最大降水影响范围、持续时间,利用欧氏距离等数学方法,研究了海河流域暴雨灾害的气象评估模型.利用该评估模型对1960 - 2008年间的海河流域暴雨进行了评估,结果表明,等级划分合理,所评估的暴雨气象等级级别与海河流域历史上对应的洪灾事件影响程度非常吻合.

关 键 词:暴雨灾害  欧氏距离  评估向量  评估模型  决策服务  海河流域

Abstract:In view of the specialty of the meteorological data and timeliness of the evaluation,HR disaster meteorological evaluation of the HRB is studied by Euclidean distance method after considering the averaged precipitation intensity,the maximum influence scope and its duration.The evaluation model is used for evaluating the HRB’s HR during 1960~2008.The results show that the evaluated meteorological grades of HR concur with the influence of the flooding events ever occurring in HRB.
Keywords:heavy rain disaster  Euclidean distance method  evaluation vectors  evaluation model  decision-making services  Haihe River Basin
