场地尺度的数字孪生:从城市尺度建模到多元小微设计干预

Site-Scale Digital Twinning:From City-Scale Modeling to Multiple Micro-Urban Interventions

本文探讨了数字孪生技术在城市规划和景观设计中的应用。数字孪生最初由制造业和工程领域开发,如今已成为在虚拟环境中复制和模拟物理世界的关键工具,有助于实现实时监控和模拟未来变革,对城市规划和景观设计具有深远的影响。尽管其应用范围广泛,但在城市景观这类不确定因素较多的环境中实施数字孪生技术,尤其是在推行通用城市尺度数字孪生的可行性方面仍存在诸多挑战。本文主张在场地尺度应用数字孪生技术,专注于在不确定因素相对较少、技术建模环境相应可控的特定城市要素(如公园、建筑物和基础设施等)中实施。这种方法强调通过一系列场地尺度的应用来创建城市数字孪生网络的重要性。该方法需要在景观和城市设计实践中进行持续的实践和检验,依赖于经济和政策环境的支撑,以促进跨学科的研发设计和市场应用。通过三项设计提案,本文探讨了场地尺度数字孪生的变革潜力,强调其通过整合市民的情感、互动和健康数据,在设计干预的虚拟-物理界面及公共空间与城市景观中发挥的作用,进而创造更具互动性、参与性和响应力的环境。

This paper explores the application of digital twins(DT) in urban planning and landscape design.Initially developed in fields such as manufacturing and engineering,DT has emerged as a critical tool for replicating and simulating the physical world within a virtual environment.Its application enables real-time monitoring and future transformation simulations,offering profound implications for urban planning and landscape design.Despite its broad applicability,implementing DT in less controlled contexts like urban landscape environments presents unique challenges,particularly drawing skepticism around the feasibility of launching a universal city-level DT.This paper advocates for site-scale DTs focusing on specific urban elements,such as parks,buildings,and infrastructure,to enable more controlled and effective modeling environments,emphasizing the importance of creating an urban DT network through serial site-scale DTs.This approach requires ongoing experimentation in landscape and urban design practices and supportive economic and policy environments to foster interdisciplinary research and design and market adoption.Drawing from three design proposals,this paper explores the transformative potential of site-scale DTs,highlighting its role in creating more interactive,participatory,and responsive environments by integrating citizen data on emotions,interactions,and health factors,thereby advancing the design-intervened virtual-physical interface of public spaces and urban landscapes.
