摘　　要：对地理信息系统中空间关系自动构建技术进行了研究 ,并在此基础上提出了基于栅格索引的结点匹配算法来实现点线拓扑关系的自动构建技术 ,建立起点、线、多边形的拓扑关系 。The paper mainly discusses the auto creating technology of topological spatial relationship, on the basis of which a crunode matching algorithm is brought forward to create the topological relation of points and lines, and the topological relationship could be set up for points, lines and polygons based on grid index. Furthermore, the implementing process of auto creating of the Topological Spatial Relationship in GIS, is also presented in this paper.
