摘　　要：藕池(管)水文站位于长江四口水系藕池河段,为荆江四口分流藕池口分支藕池河的控制站。水位~流量关系主要受洪水涨落、断面冲淤、洞庭湖回水顶托等影响,连时序绳套法定线较为复杂,流量测次多。通过对2016-2020年藕池(管)站水文资料单值化分析,选用新厂(二)水位站作为落差辅助站,采用试错法确定最优单值化方案。结果表明,水位~流量关系单值化分析结果较好,满足现行水文整编规范要求,优化精减了流量测验次数,提高了工作效率。The Ouchi(guan)station is located at the Ouchi reach of the fourth channels of the Yangtze River,which is the control station of the Ouchi river branch of the fourth channels diversion of the Jingjiang River.The relationship between water level and discharge is mainly affected by flood fluctuation,cross-section scouring and silting,backwater jacking of Dongting Lake,etc.the legal line of connecting time series rope sleeve is relatively complex,and there are many flow measurements.Through the single value analysis of hydrological data of Ouchi(guan)station from 2016 to 2020,Xinchang station is selected as the drop auxiliary station,and the trial and error method is used to determine the optimal single value scheme.The results show that the single value analysis result of water level discharge relationship is good,which meets the requirements of the current hydrological integration specification,optimizes and reduces the number of discharge tests,and improves the work efficiency.
