分形理论在城市研究中的应用

Applications of Fractal Theory to Urban Studies

本文先介绍分形理论的基础知识 :分形、分形维数及其算法。然后应用该理论探讨城市的形态与功能 :城市边界线、网络结构、土地使用、城市形态与增长、城市化空间过程等。所引述的大量证据表明城市在各个方面具有分形特征。分形模型适合用来刻画城市的空间过程 ,从而为规划设计。

Fractal theory introduced in the paper refers to fractal, fractal dimensions and their measuring methods. Then, applications of fractal theory to cities are described, which include urban boundary, network, land use, urban form and growth, and so on. Thus, there are the preliminary evidence of fractal cities and fractal simulation models which might provide new methods for urban design and policy analysis.
