摘　　要：针对水文计算中戴溪站长系列资料缺乏的情况,利用日平均水位资料对戴溪站与周边4个站的水位关系进行分析,建立戴溪站与相关代表站的线性回归关系,利用相关代表站的水位确定戴溪站水位。通过水位差分析和线性分析可知,戴溪站与相关代表站具有密切的水力联系,水位变化基本一致,线性相关关系较好。以戴溪站为因变量,4个站为自变量,按季节和水位等级划分,分别建立多元回归线性方程,对相关系数和模拟误差进行对比。分析表明,按季节划分的拟合效果最好,分析研究结果可为该站特征水位的制定提供技术支撑。Aiming at the lack of series data of Daixi station in hydrologic calculation,this paper analyzes the water level relationship between Daixi station and four surrounding stations by using the daily average water level data,establishes the linear regression relationship between Daixi station and relevant representative stations,and determines the water level of Daixi station by using the water level of relevant representative stations.Through the water level difference analysis and linear analysis,it can be seen that there is a close hydraulic connection between Daixi station and relevant representative stations,and the water level changes are basically the same,with good linear correlation.Taking Daixi station as dependent variable and four stations as independent variables,multiple regression linear equations were established according to season and water level classification respectively.The correlation coefficient and simulation error were compared,and the analysis showed that the fitting effect was best according to season.The results provide important technical support for the determination of characteristic water level of the station.
