摘　　要：城市的空间格局与社会生活各个方面息息相关,若利用GIS卓越的技术能力,探索城市空间格局的结构性特征、要素关联,挖掘其中的空间关系或其他有意义的结构模式,将为城市经济发展、资源分配、交通规划等社会问题提供知识支撑。此外若将城市空间格局与GIS空间分析相融合,将有助于架起图形与文本之间的桥梁与纽带,提升GIS空间数据挖掘水平。本文总结了城市空间格局的要素体系,并利用RCC8模型和区间代数使之与GIS中的空间关系建立对应关联,实现了由城市规划文本生成城市空间格局意向图。丰富了城市空间格局的规律性、本质性知识,弥补了多种空间关系集成研究的不足,为图形和文本的关联性知识挖掘奠定了基础。Urban spatial pattern is related to various aspects of social life closely.If the preeminent capabilities of GIS can be utilized to explore the structural characteristics and elements association of urban spatial pattern,and to mine the spatial relationship and other meaningful structural schema,many social issues such as economic development,resource allocation,transportation planning and so on can get knowledge support.Besides,the integration of urban spatial pattern and GIS spatial analysis will contribute to erect the bridge and link between graphics and text and raise the level of GIS spatial data mining.This paper summarizes the elements system of urban spatial pattern.RCC8 model and the interval algebra are also used to construct of the mapping relationship.At last the sketch map of urban spatial pattern was generated from the urban planning text.This study enriches the regular and the substantive knowledge of urban spatial pattern,compensates for defects of the research of variety spatial relationship integration,and establishes the foundation for the relevance knowledge mining of graphics and text.
