摘　　要：本文将线要素与多面要素的拓扑关系分解为简单面要素与其相关线组之间的局部拓扑关系;并将局部拓扑关系细化为线面基本拓扑关系,用度量关系对线面基本拓扑关系进行描述,提出了一种描述单线与多面要素之间拓扑关系的方法,可应用于线与多面要素数据库的建立、数据存储和查询。实验证明了其有效性。This paper decomposed the topological relations between line feature and multi-polygon features into the local topologi- cal relations between simple polygon and its correlative lines. Furthermore, the local topological relations were composed of the basic topological relations between line and polygon which can be described using metric details. Finally, a method for describing the topolo- gical relations between single line feature and multi-polygon features was proposed. And this method could be used in interrelated data- base building, data storage and data query. Experiment proved its feasibility.
