摘　　要：为研究空间数据在以三峡水库为核心的水库调度自动化系统中的高效应用,通过数据互操作、数据融合、数据集成等技术,基于空间数据引擎,对降水、调度风险、地表覆被、水下地形等空间数据进行管理,构建了多维空间数据仓库。结果表明:构建空间数据仓库是管理多维数据的有效方法,也是构建面向决策者的可视化系统基础。研究成果可为多源异构、海量的空间数据管理、分析提供支撑,也为水资源决策提供数据底板。In order to study the efficient application of spatial data in the reservoir dispatching automation system based on Three Gorges Reservoir, technologies such as data interoperability, data fusion, data integration are used, and based on spatial data engine, spatial data such as precipitation, dispatch risk, land covering, underwater terrain, etc.,are managed, and a multi-dimensional data warehouse is built.The results show that building a spatial data warehouse is an effective method for managing multidimensional data, and it is also the basis for building a decision-maker-oriented visualization system.The research results can provide support for multi-source heterogeneous and massive spatial data management and analysis, and provide a data backplane for water resources decision.
