| 摘 要： | 城市的形成和发展是一个历史过程，如何评判城市是一个深刻的哲学命题，从熵定律角度来研究城市发展，可以帮助我们建立一种新的城市发展观。城市发展是一个不可逆过程，城市作为一个开放的系统，只要能够从外部环境得到足够的负熵流以抵消内部的熵增，城市将形成耗散结构系统并朝着进化的方向发展。未来的城市应进入低熵社会，主要途径是：建立生态城市，走可持续发展的道路；建立数字城市，实现城市社会信息化；控制城市人口，合理发展城市规模。

| Abstract: | Entropy is a concept of physics to describe nonreversible process. The more the absolute value of entropy is, the more the structure of system is out of order. According to the self organization theory, an opening system will change into dissipative structural system if it is in nonlinear far away from balance, and if it can get enough negative entropy from outside to counteract positive entropy in it. Urban system is one kind of opening system, and the urban development is one of nonreversible processes in the universe. The development of urban system tends to anagenesis if it can go into dissipative structural system, otherwise, it comes into catagenesis. Urban society should be the one of low entropy in the future. In order to build low entropy cities, the best choice is to set up sustainable ecocity, to construct digital cities, to control urban population and to develop reasonable urban scale. |
