摘　　要：以数字地球科学和数据仓理论为指导,以3S技术、环境模拟技术和计算机编程技术为手段,根据空间信息与非空间信息在地理单元和空间上的存储特征,建立了基于域和对象的公共数据模型,继而构建了不同专属性的空间数据库。以此为基础,通过应用空间数据引擎和空间数据操作对象,首次对面向应用的松嫩平原土地资源空间数据仓进行了分析与设计。With the guidance of theory on digital earth and data warehouse, and with the instrument of 3 S, environmental imitation and cyber-programme, the authors have designed the public data model based on field and object according to the memory-characteristic of spatial information and non-spatial information in geographical cell and space. Whereafter, the spatial databases of different attribute have been found. The authors have analyzed and designed firstly the spatial data warehouse of land resource in Songnen Plain which is facing to application with the utilization of spatial data engine and operational object. Now the research and exploiture of it is on a preliminary phase.
