中文摘要：

基于空间数据综合分析的目的,从空间认知的角度出发,提出了以四面体为基本体元,表面TIN隐含的集成模型构想。在对点、线、面、体元之间拓扑关系精心设计的基础上,采用面向对象的思想构建了对象管理器,对空间微观数据及其相互间的复杂关系进行集成组织管理,有效地使空间对象（四面）体模型与表面（TIN）模型在数据层面上得到有机整合,实现了两者之间的无缝结合。在此基础上完成了对上述集成模型的构建,并实现了对模型的拣选、切割等操作,实例验证了该模型的正确性、可行性。

英文摘要：

For the purpose of synthetical analysis of spatial data,an integrated model from the view of spatial cognition is advanced,which contains the surface TIN implicitly,and takes the tetrahedron as the basic volume element.On the basis of elaborate design of the topological relationships between the node,edge,facet and volume,an object-manager is designed to organize and manage the microcosmic spatial data together with their topological,associative relationships.With the object-manager,the surface TIN model and TEN model can be unified at the data level,which enables a seamless combination of these two models.The mechanisms of operations on the so-constructed models,such as clipping,uncovering,etc,are also covered.A case study is also given to verify the validity and feasibility of the integrated TEN model based on the object-manager.
