摘　　要：针对水资源数据具有复杂、数据量大、多源异构等特点,论文提出了松花江流域水资源空间数据仓库的总体设计方案,在数据集成、数据清洗、数据简化与数据转换等预处理操作的基础上,构建了多维数据模型,并实现了基于空间OLAP的多维数据分析,为水资源决策分析提供有效的数据支持。In allusion to complexity, abundance, multi-sources and heterogeneity of water resources data, spatial data warehouse technology is adopted to design subject-oriented, integrated and steady multidimensional datasets, in order to supply efficient data for water resources decision. This paper designs the spatial data warehouses scheme of water resources in Songhua River basin, and reali- zes data pretreatment including data integration, data cleaning, data transformation and data reduction. Then it constructs star schema data model and analyzes multidimensional data based on spatial OLAP. Finally it archives the improvement of knowledge discovery and data mining.
