城市区域发展的梯度性假设——世界视野中的城市文明走向

ASMU Gradient Hypothesis of Urban-region Development: Urban Civilization Trend in the World Vision

人类文明经历了游牧民的帐篷文明、农耕社会的村镇文明和工业社会的都市文明。从城市发展的历史与未来推测,城市的发展模式是:城市与区域社会分离到城市与区域社会发展融合的四个梯度——邻域、近域、广域到全域,最终实现城市文明扩及全社会。城市文明超出城市本身的发展范畴,成为了区域社会发展的引擎或动力,带动着社会的全面发展。城市从城区到城外,从近郊到远郊,从中心城市到边缘城市的扩展,都是城市文明向外梯度扩展的表现。欧美发达国家城市的相对均衡发展之路,拉丁美洲国家的过度城市化所导致的城市与区域社会经济发展脱节现象,为我们的城市与区域社会发展提供了经验与教训。

Human civilization has experienced the tent civilization nomad society, village and town civilization of agricultural society, and urban civilization of industrial society. The model of urban development can be considered as a gradient from the separation to the fusion of city and region： adjacency, surrounding, macrozone and universal （the ASMU model for short）, eventually expanding urban civilization outwards to all lands. Urban civilization has exceeded the city scope and become the engine or power of regional society development, and drove its integrated development. Cities that expanded from inner area to outer areas, from suburb to outer areas, from key cities to edge cities, are all manifestation of urban civilization＇s gradient outward extension. That the relatively even development of cities in developed countries, as well as the excessive urbanization of city and region in Latin American, has provided valuable experiences for China＇s urban and regional development.
