摘要
为解决永定河流域数据分散、质量不高,二三维场景应用效率低下的问题,更好支撑数字孪生永定河预报、预警、预演、预案功能及“2+N”业务应用,建设数字孪生永定河数据底板。汇聚基础、监测、业务管理、地理空间和跨行业共享等多源时空数据,基于数据原生技术与中台化思想,搭建具有数据汇聚、数据建模、数据治理和数据贯通服务能力的数据管理平台,构建流域多尺度高保真数字化场景,支持业务“四预”功能的计算、模拟和展现。在海河“23·7”流域性特大洪水模拟与复盘、永定河生态水量调度等“2+N”业务应用中,数据管理平台能够提供完整、准确、及时的数据,同时耦合水利专业模型,实现数字化场景智能模拟与精准决策。永定河数据底板的构建可奠定数字孪生永定河建设应用的坚实基础,也可为下一步数字孪生海河的全面建设提供典型样例。
To address the challenges of fragmented data,low data quality,and inefficiencies in 2D and 3D scene applications within the Yongding River Basin,and to better support the forecasting,early warning,rehearsal,and planning functions,as well as the“2+N”business applications of the digital twin Yongding River,a foundational data platform was developed.This platform integrated diverse spatiotemporal data sources,including basic,monitoring,business management,geospatial,and cross-sectoral shared data.Leveraging data-native technologies and a middleplatform architecture,a data management system with capabilities in data aggregation,modeling,governance,and integration services was established.It enabled the construction of high-fi delity,multi-scale digital scenarios of the river basin to support the computation,simulation,and visualization of the“Four Pre”functions.In key applications such as the simulation and review of the July 2023 Haihe River Basin extreme fl ood event(“23·7”)and ecological water dispatching in the Yongding River,the data management system provided complete,accurate,and timely data support.It also enabled intelligent simulation and precise decision-making by coupling hydrological models within a unifi ed digital environment.The construction of the Yongding River data foundation lays a solid basis for the implementation of the digital twin Yongding River and serves as a representative example for the comprehensive development of the digital twin Haihe River.
