摘　　要：空间目标处于一定的时间与空间中,时态拓扑关系和空间拓扑关系经常交织在一起,形成时空拓扑关系,因此有必要在统一框架下研究时空拓扑关系。基于Allen对时态拓扑关系和Egenhofer对空间拓扑关系的研究,对时态拓扑关系和空间拓扑关系分别采用3×3的矩阵进行描述,将时空拓扑关系表示为3×6的矩阵,并描述了简单面/面之间的104种时空拓扑关系。在研究时态拓扑关系推理和空间拓扑关系推理的基础上,提出了一种时空拓扑关系推理方法。该文提出的时空拓扑关系描述和推理方法对于拓展时空拓扑关系的研究具有重要意义。Spatial object is the unit of space and time. Spatial-temporal topological relationship is composed of temporal topological relationship in time dimension and spatial topological relationship in spatial dimension. It is essential to study on spatial-temporal topological relationships in a unified framework. On the analysis of Allen＇s 13 temporal topological relationships and Egenhofer＇s 8 spatial relationships on regions, the integration framework for spatial-temporal topological relationships is proposed. In this paper, temporal topological relationships and spatial topological relationships are represented by 3 X 3 matrix respectively, so the authors proposed to use 3 × 6 matrix to depict spatial-temporal topological relationships. As many as 13 ×8 = 104 kinds of spatial-temporal topological relationships are illustrated. On the analysis of temporal topological relationships and spatial topological relationships reasoning,a spatial-temporal topological relationships reasoning method is proposed. Spatial-temporal topological relationships representation and reasoning method can be contributed to the research of spatial-temporal topological relationships.
