中文摘要：

空间关系是GIS的重要信息和理论研究基础。空间关系描述的准确性、完备性、直观性直接影响到地理学分析和地图制图的效果。当前，国际国内在地理要素空间拓扑关系模型表达和拓扑关系挖掘与描述方面做了大量研究，解决了很多关键问题也发现了许多新问题。本文在前人研究的基础上，提出基于直线段相交特征的局部直线段拓扑关系识别方法，并结合拓扑链模型对线线空间关系进行细化描述。该方法不仅具有线要素集合划分的优点还有线线间空间关系细化描述的直观性，同时简化了线线空间关系的细化计算。

英文摘要：

Describing spatial relationship is a critical and basic theoretical of GIS. The exactitude of geographic analysis and cartographic result based on the accuracy, completeness and intuition of expression of spatial relationship.Currently, in the International and domestic fields, a lot of researchers have done abundant work about creating topological model and mining topological relationship. As their excellent job, a series basic theory and method have discovered. Based on the former job, this paper presents a local line-line topological recognition method based on the linear segment intersection feature. Integrate with Line-line topology chain model to describe the Line-line spatial relationship, and SVM to recognize linear segment intersection feature, the refined calculation of Line-line spatial relationship becomes simplify.
