数字孪生水圈:理论内涵、基础模型与关键技术
Digital twin hydrosphere:theoretical connotations,a foundational model and key technologies
摘要
Abstract
In response to the challenge that conventional water cycle simulation and regulation can hardly address the systemic complexities across climatic zones,spheres,and multi-scale processes-particularly their inadequacy in supporting command,dispatch,and decision-making for large-scale national water networks-this study proposes the Digital Twin Hydrosphere,which is envisioned as a Hydrosphere Simulator.It clarifies the definition of the Digi-tal Twin Hydrosphere and its relationship with the Digital Twin Watershed,the Digital Twin Water Network,and the Digital Twin Water Conservancy Project.The connotations of the Digital Twin Hydrosphere are analyzed from four dimensions:ontology,epistemology,methodology,and axiology.Essential characteristics are identified,including integration of all elements and three-dimensional symbiosis,holistic cognition and collaborative intelligence,forward-looking deduction and adaptive decision-making,and knowledge accumulation and continuous evolution.A foundational model consisting of an information model and a system model was established with analyses of its core capabilities,scientific challenges,and key technological breakthroughs to be made.Enabling pathways were also dis-cussed.The study shows that the Digital Twin Hydrosphere can significantly enhance systematic understanding,sce-nario simulation,and risk prevention and control capabilities for the multi-scale"natural-social"dual water cycle,providing theoretical foundations and technological pathways for the paradigm shift in water system governance from"experience-driven"to"data-and model-driven".关键词
