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 elab-orated.The development and innovation process of the method in the past 50 years and its practical application in the whole hydro-logical field were sorted out.Finally,the role of the method in compilation system for hydrological data,hydrometric station net-work 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 sta-tionary and tour gauging,prioritizing tour gauging,automatic reporting,and emergency supplementation",and improved the effi-ciency 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.
