摘要: 21世纪以来，数字孪生进入城市规划与治理领域，加快了城市的感知和问题反馈的过程，形成了时间、空间和人之间新的互动机制。数字孪生城市的挑战来自城市的复杂性，提出以人为主的沉浸参与式角度来重新定义空间，强调空间的多维度延伸，以空间流形的模型为基础，建立起数字孪生城市的空间表达方式及其升维与降维的计算逻辑。基于此，探讨数字孪生赋能下的“互动生成式”规划模式：通过数字孪生的参数化设计，以人为主体，不断调整和实时反馈城市的各项规划参数，构建不断演进的数字孪生的规划治理系统及政策。
Abstract: Since the 21st century, digital twins have entered the field of urban planning and governance, accelerating the process of urban perception and problem feedback, and forming a new interactive mechanism among time, space and people. This paper argues that the digital twin city faces the challenge of the complexity of the city. In order to meet this challenge, it redefines space from the point of view of human-centered immersive participatory, addressing the multi-dimensional extensions of the spaces, and establishing the spatial expression model of digital twin city and its calculation logic of upgrading and reducing dimensionality based on the model of spatial manifold. Then this paper discusses the interactively generative planning model empowered by digital twins. Taking people as main actors and adopting the parametric design of digital twins, it continuously adjusts real-time feedback of various planning parameters of the city, and thus builds an evolving digital twins' planning and governance system and its inherent policies.
