城市空间形态的分形维数及应用

城市空间形态是城市这一复杂巨系统中重要组成部分,定量研究城市空间特性对城市科学管理与规划具有重要的实践意义.城市交通网络是城市空间形态发展的基础骨架,而城市外部形态是城市自组织演变的结果.在GIS环境下,利用分形这一技术手段,对城市交通网络空间组织结构特征及城市外部空间形态演变进行分析探讨,得出分维数可以揭示城市内、外空间形态复杂变化的一般性规律.

Fractal dimension of urban spatial morphology and its application

Urban spatial morphology is important proportion of the urban complex and huge system; and the quantitatively researching urban spatial characteristic has significant practice meaning for urban management and planning. Urban traffic network is basic framework of urban spatial morphology; and the outer form is the result of urban self-organization evolution. Based on the GIS circumstance, the spatial configuration characteristic of urban traffic network and the evolution of urban outer spatial morphology are analyzed and discussed using the fractals in the paper. We draw some conclusions that the universality rule of urban inner and outer spatial morphology can be shown by the fractal dimension.
