摘要： 提出了一种在空间数据仓库系统下，基于主题和角色的统一的权限控制机制。将空间数据仓库的内部权限与外部权限、空间数据权限和属性数据权限统一起来。并用以支持国家自然科学基金资助重点项目－－“三江并流”代表性植物空间数据仓库及其多样性研究项目的实验平台的构建。

Abstract: An access control mechanism, which is uniform, topic-based and role-based, is proposed for spatial data warehouse. It unifies inner-privilege and outer-privilege, spatial data privilege and attribute data privilege of spatial data warehouse. It is used to support constructing for experiment platform in national natural science foundation project－－the studying project about “the three parallel rivers area” representative plant spatial data warehouse and biological diversity.
