Abstract:

Chengdu City, which is located in the west of Sichuan Plain, is surrounded with hilly and mountainous areas. In analysis of the spatial structure of the urban system in Chengdu Plain, the authors draw a new conclusion that the urban system is made up of a series of pentagons. Based on geometry theories, the pentagon, as a basic unit, has a fractal and golden section character. Then, the authors explained why Chengdu City should expand to its eastern or southern directions, and hypothesized that the urban pentagonal spatial structure is an imbalanced state and hexagonal is balanced. With the development of urban economy and the growth of population, urban spatial structure will change from balance to imbalance, then imbalance to balance, being an infinite cycle. The urban planning and industry structure adjustment must obey this law. Finally, using the hypothesis, this paper presents a future urban spatial pattern for Chengdu City.

Key words: spatial structure, urban system, Chengdu City
