水位流量关系拟合是水文资料整编的核心工作，其精度直接影响资料整编成果质量。在水文现代化建设加快推进的背景下，水文监测站点数量急剧增加，传统的人工定线方式难以适应工作需求。针对水位流量关系拟合问题，提出将最小二乘法(LSM)与正交函数(OF)相结合构建了LSM-OF模型对曲线参数进行优化，并以云南省上桥头、拖顶站为例，将该模型与LSM、人工定线计算结果进行对比。结果表明，该模型能充分满足水文资料整编技术要求，可显著提升定线精度与工作效率，具有广阔应用前景。
Abstract：Water level-discharge relationship fitting is the core work of hydrological data compilation, and its accuracy directly affects the quality of data compilation results. Against the backdrop of accelerated hydrological modernization, the number of hydrological monitoring stations has increased sharply, making it difficult for traditional manual wiring to adapt to work needs. In response to the water level-discharge relationship fitting problem, combined the least squares method(LSM) with the orthogonal function(OF) is used to construct the LSM-OF model to optimize the curve parameters. Taking the Shangqiaotou and Tuoding stations in Yunnan Province as examples, the model is compared with the calculation results of LSM and manual alignment method. The results indicate that the model can fully meet the technical requirements of hydrological data compilation, significantly improve the accuracy and efficiency of alignment, and has broad application prospects.
