摘　　要：首先表述了空间数据仓库的三个核心思想;其次设计出了空间数据仓库的概念框架,着重描述了空间数据仓库的外部结构、内部结构以及各组成模块的工作流程,设计出了空间数据仓库认知过程的概念框图,并对认知的基本概念进行了描述,表述了认知过程14个世界模型和13个转换算子的基本内容,并用代数系统给出了严格定义;最后得出的结论是,研制空间数据仓库十分必要,以支持我国的空间数据基础设施建设。It expressed three key concepts on spatial data warehouse. It designed its conceptual frame that was exterior structure and interior structure, and explained its work step. It designed its conceptual frame of cognition process and described basic concept of cognition. It explained basic content of fourteen world models and thirteen transforming operators, and gived formalism definition based on algebraic system. It concluded that it was necessary to study spatial data warehouse in order to support spatial data infrastructure.
