分形城市与城市规划

分形城市是自组织城市中非常重要的内容之一,也是与城市规划关系最为密切的自组织城市研究领域。本文首先阐述分形城市的基本概念及其测度方法,然后论证分形思想在城市规划中的应用思路和发展前景。分形是大自然的优化结构,分形体能够最有效地占据空间。借助分形思想规划城市和城市体系,将能使我们更为有效地利用地理空间和环境,美化人类的家园。

FRACTAL CITIES AND CITY PLANNING

The power-law associated with fractalsis often regarded as a signature of feasible optimalitythus yielding further support to the suggestion thatoptimality of the system as a whole explains the dy-namic origin of fractal forms in nature. Many empiri-cal studies have shown that cities have fractalstructures, and fractal structure is the optimized struc-ture of nature. In fact, a fractal body can occupy thespace in the most efficient pattern. In this sense,planned with the idea of fractals, a city will be able tomake the best of the limited geographical space. Thispaper explains what is fractal cities, how to under-stand and measure fractal cities, and how to plan thefuture cities using the idea of fractals. Fractal cities isone of the significant fields of self-organized cities,the development of the principle, theory, and methodof fractal city planning relies heavily on the advanceof the theory of self-organized cities as a whole.
