模型城市

Modeling cities

Marc Barthelemy

摘要:

城市是一个由大量要素和主体相互作用的系统,可以被视为复杂系统的象征。对这些系统进行建模是一个真正的挑战,并引发了许多学科的兴趣,如定量地理学,空间经济学,地理信息学和城市化,以及最近的物理学。物理学通过带来能够连接理论和经验结果的工具和概念发挥着重要作用,我们将在城市的一些基本方面说明这一点:它们的表面积和人口的增长,它们的空间组织以及活动的空间分布。我们将提出最先进的结果和模型,但也开放的问题,我们仍然有一个部分的理解和物理方法可能特别有帮助。我们将以讨论建立城市科学的可能性来结束这篇简短的评论。

英文摘要:

Cities are systems with a large number of constituents and agents interacting with each other and can be considered as emblematic of complex systems. Modeling these systems is a real challenge and triggered the interest of many disciplines such as quantitative geography, spatial economics, geomatics and urbanism, and more recently physics. (Statistical) Physics plays a major role by bringing tools and concepts able to bridge theory and empirical results, and we will illustrate this on some fundamental aspects of cities: the growth of their surface area and their population, their spatial organization, and the spatial distribution of activities. We will present state-of-the-art results and models but also open problems for which we still have a partial understanding and where physics approaches could be particularly helpful. We will end this short review with a discussion about the possibility of constructing a science of cities.
