摘　　要：为通过数字孪生构建物理流域与数字流域关联,实现对流域资源、环境、生态等多方面的监测、分析与优化配置,探讨了数字孪生流域建设过程中知识图谱的应用前景、构建方法、应用和面临的挑战。在知识工程相关技术基础上,以甘肃省白龙江干流舟曲县河段流域为例,对其中水利对象、防洪保护对象及其之间的关联关系进行了知识表示、抽取、融合和推理,构建了可视化、交互式的流域知识拓扑图,使其为数字孪生流域管理提供需求分析、知识检索、决策分析等应用价值,并对可能面临的挑战进行了分析,如需提升数据质量与标准化问题、或将面临的技术瓶颈等。研究成果可为水利工程知识图谱建设与推广应用提供参考。In order to construct the association between physical watershed and digital watershed through digital twin and realize the monitoring,analysis and optimal allocation of resources,environment,ecology and other aspects of the watershed,the application prospect,construction method,application and challenges faced by the knowledge map during the construction of digital twin watershed were discussed.On the basis of knowledge engineering related technology,taking the river basin of Zhouqu County section of the main stream of Bailong River in Gansu Province as an example,the knowledge representation,extraction,fusion and reasoning of water conservation objects,flood protection objects and their associated relationships were carried out,and the visualized and interactive knowledge topology map of the basin was constructed.The value of demand analysis,knowledge retrieval,decision-making analysis and other applications for the management of digital twin river basin were provided.The possible challenges were analyzed,such as the need to improve data quality and standardization or will face technical bottlenecks,etc.The research results can provide a reference for the construction and promotion of the application of knowledge map of water conservancy engineering.
