摘　　要：通过收集和处理2015—2020年望虞河代表站的水位、潮位和排水量数据,采用多元回归法对上游水位、长江潮位和望虞河排水流量进行回归分析,计算得到望虞河的排水能力。另外,比较多元回归法和一潮推流法计算的日排水量发现,多元回归法计算公式的系数固定,能客观反映望虞河的排水能力,而一潮推流法计算公式的率定参数每年都有变化,在实际应用中较为复杂。研究结果表明,望虞河的排水能力与上游水位呈正相关关系,与长江潮位呈负相关关系。By collecting and processing water level,tidal level and displacement data of representative stations of Wangyu River from 2015 to 2020,the water level,tidal level and drainage discharge of Wangyu River in the upper reaches of the Yangtze River were analyzed by using multiple regression method,and the drainage capacity of Wangyu River was calculated.In addition,compared with the daily displacement calculated by multiple regression method and one-tidal push method,it's founded that the coefficient of multiple regression method was fixed,which could objectively reflect the drainage capacity of the Wangyu River,while the calibration parameters of the one-tidal push method vary every year,which was more complex in practical application.The results showed that the drainage capacity of Wangyu River was positively correlated with the upstream water level,and negatively correlated with the tidal level of the Yangtze River.
