摘　　要：梅田湖水文站水位–流量关系受洪水涨落、断面冲淤以及洪水顶托影响,呈复式绳套关系。根据本站水文特性,以下游罗文窖水文站作为落差辅助站,选取2016~2020年实测资料,采用落差指数法进行单值化分析。结果表明,使用落差指数法推算的成果与连时序法基本相符,满足现行整编规范要求。The water level-flow relationship of Meitianhu hydrological station is influenced by flood fluctuation, erosion-deposition variation, and backwater, so it presents a double loop curve relationship. According to the hydrological characteristics of the station, the downstream Luowenjiao hydrologic station is used as the auxiliary station. With measured data from 2016 to 2020, the comprehensive fall exponent method is used for uniformization of water level-flow relation. The analysis shows that the results calculated by the comprehensive fall exponent method are basically consistent with the continuous time series method, and meet the requirements of the current reorganization specification.
