摘　　要：数据底板作为数字孪生平台核心组成部分,在支撑数字孪生水利建设中作为“算据”发挥着关键性的基础作用。在数据底板可视化方面目前还存在数据要素标准不统一、融合渲染方法不明确、业务场景难支撑的问题,特别是大尺度三维数据底板如何融合构建、共享、更新与应用,尚未形成高效的解决方案。根据数字孪生水利建设数据底板建设思路,详细阐述了当前多源多级数据融合方法和业务可视化同步映射技术,并以淮河流域水利要素可视化模型构建开展实践探索。结果表明:多源异构数据标准化治理与可视化模型轻量化渲染在数据底板建设中至关重要,不仅能够支持流域尺度物理实体与数字要素的同步映射,也能够增强多场景的业务服务能力,为流域水安全保障提供关键数据支持。As a core component of the digital twin platform,the data base plate plays a key fundamental role as an"arithmetic data"in supporting the construction of digital twin water sector.In the visualization of the data base plate,there are still data element standards are not consistent,fusion rendering method is not clear,business scenarios are difficult to support,there is no good solutione for specially how to integrate,build,share and update the large-scale 3D base plate.This paper focuses on the idea of data base plate construction of digital twin water sector,elaborates the multi-level data fusion method and business visualization synchronous mapping technology,and explores the construction and application of visualization model for the entire Huai River basin.The results show that standardized governance of multi-source heterogeneous data and lightweight rendering of visualization models are crucial,not only to support the synchronous mapping of basinal physical entities and digital elements,but also to enhance multi-scenario business decision-making capabilities and to provide data support for basin water security.
