Abstract：Building digital twin basins is a vital means of enhancing national water security.Accelerating the development of a digital twin Yellow River system equipped with forecasting,early warning,rehearsal,and contingency planning functions is an urgent requirement for implementing the national strategy of ecological protection and high-quality development in the Yellow River basin.It serves as a strong driver and support for advancing high-quality water conservancy development in the basin and improving water security capabilities in the new stage.By constructing the Digital Twin Yellow River,water management in the basin is being transformed toward digitalization,networking,and intelligent operations.This paper reviews the historical evolution of informatization in Yellow River governance,analyzes existing issues such as insufficient coordination among different stages of information systems,and clarifies the background,significance,and foundation of the"full-chain"construction of the Digital Twin Yellow River.Based on construction needs,a"full-chain"development concept encompassing information collection,communication transmission,data management,system development,and operation and maintenance is proposed.The core framework,logical structure,and key technologies are defined.The overall architecture includes building the digital twin platform,upgrading information infrastructure,developing"2+N"business applications,and improving network security and support systems.The paper further explores the synergy objectives and major tasks of each link in the"full chain",aiming to create an integrated,coherent,and interconnected system.Preliminary achievements and practical experiences are presented to serve as a reference for planning and constructing digital twin systems for the Yellow River and other river basins.
