摘　　要：针对上海市平原感潮河网地区闸控河流复杂的水流过程,为获得完整、准确、可靠的引排水量数据,通过对大治河东闸站和三甲港闸站现有监测分析获得的水位、水量、闸门运行工况等数据进行多元相关分析,得到引排水量与水位、引排时间、水闸过水断面面积的相关关系,并进行回归计算。回归计算结果与实测结果的误差分析结果表明:这种相关关系是比较可靠的,相对误差和标准偏差等均在可接受的范围内。说明用这种方法插补计算缺测期间的引排水量具有一定的可行性,可弥补因各种原因导致缺测带来的水量成果缺失的不足。该方法具有一定的普适性,可用于其他闸控河流水量计算分析,也可避免水位流量关系不显著、不稳定带来的困扰。In order to obtain complete,accurate,and reliable water diversion or drainage data for the complex flow process of sluice controlled rivers in the plain tidal river network of Shanghai,this paper conducts a multivariate correlation analysis on water level,water volume,gate operating conditions from monitoring and analysis of the Dazhi River East Gate Station and Sanjiagang Gate Station,leading to the correlation between water volume and the water level,the diversion or drainage time,and the cross section area of the sluice.Thus,regression calculation can be carried out.The error analysis results of regression calculation and measured results indicate that the correlation is relatively reliable,and the relative error and standard deviation are acceptable.By applying this method to interpolate and calculate the water diversion or drainage amount during measurement absence,it is feasible to compensate for the lack of water yield caused by measurement absence due to various reasons.It is universal for this method be applied in calculation and analysis of water flow in other sluice controlled rivers,solving the problems of inconspicuous and unstable relationship between water level and discharge.
