摘要
利用长江下游地区２１个气象站的降水资料分析了区域性的异常雨涝气候事件、同时根据历史上农业雨涝受灾情况确定了异常雨涝气候事件的严重程度指标和影响评估的模型，该模型简便、实用，可用于日常气候业务服务。
The precipitation data of 21 stations in the lower reach of Changjiang River are used for analyses of regional abnormal waterlogging events. The indexes to judge the serious level of the abnormal waterlogging events are determined based on the historical agricultural waterlogging disaster in this region. A simple. convenient and practical model is established, which can be used in routine climatic business and service.
