摘　　要：数字孪生流域是通过综合运用新一代信息技术及其多种技术组合,构建“平行于”物理流域特征数据映射形成的数字空间,在流域数字空间中实现流域仿真、模拟及推演,最终实现人机联合决策和调度决策管理。针对物理流域、联结计算、数据获取、数字孪生体模型及其孪生服务等数字孪生流域的核心要素,系统开展了数字孪生流域特征数据获取、映射镜像、体系结构及数字孪生体模型构建方法的研究,提出了数字孪生流域的内涵、基于ABCDMEETS的数字孪生流域体系结构及数字孪生流域模型的构建方法。研究成果可为数字孪生流域建设提供理论、方法指导及技术支撑。The digital twin basin constructs a digital space formed by mapping the characteristic data“parallel”to the physical basin through the comprehensive application of the new generation of information technology and its combina⁃tion of many technologies,realizing the simulation,emulation and deduction of the basin in the basin digital space,and realizing the man-machine joint decision-making and regulation decision-making management.Aiming at the core ele⁃ments of the digital twin basin,such as physical basin,connection calculation,data acquisition,digital twin model and its twin service,the research on digital twin basin characteristic data acquisition,mapping image,system structure and digital twin model construction method is systematically carried out,and the connotation of digital twin basin,the archi⁃tecture of digital twin basin based on ABCDMEETS and the construction method of digital twin basin model is proposed.The research results can provide theoretical,methodological guidance and technical support for the construction of a dig⁃ital twin basin.
