　　Abstract: In March 2022, the Ministry of Water Resources issued the Technical Guideline for Development of Digital Twin River Basins (Trial), which clarifies detailed development content and technical requirements of digital twin river basins. This paper introduces the construction background, definition, construction scope and goals, construction principles and other construction connotations of the digital twin river basins, clarifies the overall framework of smart water conservancy and the digital twin river basins construction framework, further clarifies the interrelationship, and explains in detail the data baseboard, model platform, and knowledge platform. The specific construction tasks of the two main components of the digital twin platform and the information infrastructure composed of the water conservancy perception network, the water conservancy information network, and the water conservancy cloud are analyzed in detail, and the specific functional requirements and technical points involved are analyzed in detail. It explains the issues of what to build digital twin river basins, what standards to be reached, and the technical aspects that need to be mastered, and explain the important issues and integration and sharing requirements involved during the development of digital twin river basins, such as data security, especially the security application of geospatial data.
