摘　　要：数字地球建设要求广泛共享空间信息，空间数据仓库则为空间信息的有效管理和大众分发提供了有效的工具。文中分析了建设、使用空间数据仓库的背景，探讨了它的建立策略和总体体系结构。然后讨论了空间数据仓库的建设步骤，基于这些理论基础。Digital Earth calls for the sharing of spatial information, spatial data warehouse (SDW) is a convenient way for managing and distributing information among public. In this paper, the society and institutional context of building spatial data warehouse is given, that is followed by the discussing of strategies used when constructing SDW and architecture of SDW. Then related construction steps of SDW are introduced in detail. Based on these theories discussed, a prototype of SDW is designed and implemented to display how to build a SDW.
