目前,我国在采用电算技术进行水文资料整编工作中,对于呈单一曲线的水位流量关系提出了一些方法和程序,并取得了一定的成绩。但是,许多测站受到变动回水与洪水涨落等因素的影响,水位流量关系呈现出极为复杂的非单值关系。对于这类情况,国内通常采用一元三点插值或样条函数等插值方法,不仅工作量大,而且无法摆脱手工定线、选取节点等手工操作,因而无法实现电算整编的自动化。随着测验技术的改进和水文资料中心的建立, At present, some methods and procedures have been put forward for the relationship between the water level and the flow in a single curve in the reorganization of hydrological data by using computer technology in our country. Some achievements have been made. However, many stations are affected by such factors as fluctuating backwaters and flood fluctuations, and the relationship between water level and discharge presents an extremely complex non-singular relationship. For such cases, the interpolation method such as one yuan three-point interpolation or spline function is usually adopted in China. Not only the workload is heavy, but also the manual operation such as manual alignment and selection of nodes can not be eliminated. Therefore, it is impossible to automate the reorganization of the computer. With the improvement of testing techniques and the establishment of hydrological data centers,
