摘 要: 本文从耗散结构的理论出发,通过剖析城市生态系统的结构及其能量流动的规律性,分析了城市不同发展时期的能流本质,说明不同城市的发展状态将呈现出金字塔的结构.作者认为信息流在城市的发展中起着重要的作用,并将各种能量指标应用到了城市的宏观调控及决策中. On the Basis of the theory Energy Dissipation, this paper studied the laws of structure and energyflow in urban ecosystem for their different development durations, showed the number of various developing states of cities is similar to Pyramid Structure. Information flow plays an important role in urban ecosystem's growing. The energyflow indexes this paper studied out are the foundation of urban regulation.
