基于GIS空间分析的北京城市空间发展

Urban spatial development of Beijing supported by GIS spatial analysis

根据城市空间相互作用理论和城市综合引力模型 ,以北京市空间发展为例 ,探讨了应用地理信息系统 (GIS)研究城市空间发展的方法流程。在 CIS支持下 ,建立了空间数据库和属性数据库 ,并运用 GIS的多种空间分析功能 ,通过发展背景分析、发展轴线确定、引力参数定义、城市距离确定、质量数据处理等具体过程 ,综合计算了北京市的空间发展潜力。结果表明 ,北京市未来的空间发展首先应该面向廊坊市、天津市。

The spatial development of Beijing was studied using the theory of spatial interaction and a model for attraction between cities, supported by the spatial analysis functions of the Geographic Information System (GIS). The theoretical basis and the method are presented. A spatial database and an attribute database were setup based on the GIS. Many kinds of spatial analysis functions of GIS were applied to calculate the potential spatial development of Beijing. The conclusion show that the future development of Beijing will be in the southeast direction foreards many cities, such as Tianjin, Langfang, and Huanghua.
