摘　　要：目前对于空间拓扑关系的研究较多,且取得了丰硕的成果,但成果主要集中在确定的空间数据,对于不确定性空间数据的拓扑关系研究较少。引入粗集研究了空间数据面实体之间的拓扑关系。由于考虑了空间数据的不确定性,因而得到的拓扑关系是合理和科学的,其研究结果是现有拓扑关系理论的一个重要的补充。At present, the research of spatial topological relationship is very much and achieved fruitful results. But the main results mainly concentrated in the certainty spatial data. It is less for the study of topological relations of spatial data uncertainty. This paper adept rough set to study topological relationship between area and area. Because this method considered spatial data uncertainty, the result is reasonable and scientific. The method is a supplement to the existing theory of topological relationship.
