摘　　要：水位流量关系单值化方法是实现水文监测体系创新发展的重要基础。为此,系统阐述了水位流量关系单值化方法的基本原理,回顾了水位流量关系单值化方法在过去50 a的发展与创新历程,以及目前在整个水文领域的实际应用情况,展望了水位流量关系单值化方法在整编系统、站网规划、相应流量报汛等方面的作用。研究表明:水位流量关系单值化方法推动了“驻巡结合,巡测优先,测报自动,应急补充”水文现代化发展模式的形成;提高了水文测站单值化方案的效率,投产后的流量测次比历年平均流量测次减少50%~73%以上。研究成果可为现代化水文监测体系建设提供参考。The single-valued method of stage-discharge relation is an important basis for the innovation and development of hydrological monitoring system in the hydrological field.In this study,the basic principles of this method were systematically elaborated.The development and innovation process of the method in the past 50 years and its practical application in the whole hydrological field were sorted out.Finally,the role of the method in compilation system for hydrological data,hydrometric station network planning,and corresponding flood flow reporting in the future was prospected.The results showed that the single-valued method of stage-discharge relation has promoted the formation of a modern hydrological development model of"combining stationary and tour gauging,prioritizing tour gauging,automatic reporting,and emergency supplementation",and improved the efficiency of the hydrological station single value scheme.The mean flow measurement frequency has decreased by more than 50%~73%compared to previous years.The research results can provide reference for the construction of modern hydrological monitoring system.
