摘　　要：介绍基于分布式数据库技术、网络通信技术、地理信息系统技术的空间数据仓库的设计方法。以福建省沿海地区遗迹保护区为例,搭建了一个分布式的空间数据仓库。在此基础上实现以地区行政级别、类型划分及保护区一般信息为维度的多粒度数据部署。并以本数据仓库为例,根据不同的空间联机分析(OLAP)服务请求,动态创建数据立方体,完成OLAP服务并返回空间OLAP结果。This paper introduces a method of designing a spatial data warehouse based on the technologies of distributed databases, network communication and geographic information system. With the dataset of protected sites in the costal areas of Fujian Province, a distributed spatial data warehouse is built. It arranges data with different dimensions and layers based on administrative and types division as well as regular information of the sites. With an instance of this data warehouse, it successfully creates data cube dynamically according to different OLAP service requests, then accomplishes the OLAP services and returns spatial OLAP results to users.
