摘 要：人口增长、城市的持续发展，这些都需要我们用一种新方法来对城市进行深入的观察研究。如今，一门新科学正在兴起，它以大数据、城市模拟和网络理论为基础，为规划者和决策者提供了一种全新的视角来审视当前和未来的城市。本文从以下四个方面简要介绍新科学：聚合动力学；形式和功能；高频城市；规划新工具新技术。本文举例说明了这种新科学是如何展现实时城市以及城市的结构和功能边界，同时探讨了在未来城市规划和政策制定的实践过程中，可对这种新科学进行的深入探索。
Abstract:Demographic growth and the continued evolution of cities call for a new approach to better observe and research our understanding of cities. A new science based on big data, urban modelling and network theory is emerging, providing a different and rather new perspective for planners and decision-makers so that they might learn about both current and future cities. In this article, the new science is briefly introduced from four aspects: Aggregate dynamics; Form and function; High frequency cities; and New tools & techniques for planning. Examples are given to show how this new science illustrates the real-time city, as well as the structure and functional boundaries of a city, while future practice and further exploration of this new science in urban planning and policy making are explored.
