论文摘要
我们提出了一个现象学非平衡框架,用于建模城市的演变,该框架将城市内部的安置描述为不可逆的扩散过程。我们使用澳大利亚首都城市的实际迁移数据来验证此框架。关于住宅搬迁,人口被证明由两个不同的组组成,表现出不同的搬迁频率。在开发框架的背景下,这些组可以被解释为二进制混合物的两个组成部分,每个组成部分都有其自身的扩散放松时间。使用这种方法,我们可以对城市的空间结构进行长期预测,从而定义了它们的均衡种群分布。
We propose a phenomenological non-equilibrium framework for modelling the evolution of cities which describes the intra-urban resettlement as an irreversible diffusive process. We validate this framework using the actual migration data for the Australian capital cities. With respect to the residential relocation, the population is shown to be composed of two distinct groups, exhibiting different relocation frequencies. In the context of the developed framework, these groups can be interpreted as two components of a binary mixture, each with its own diffusive relaxation time. Using this approach, we obtain long-term predictions of the cities' spatial structure, which defines their equilibrium population distribution.
