数字孪生城市的驱动力、功能框架与建设路径

The Driving Force,Functional Framework and Construction Path of Digital Twin Cities

在城市资源、环境、物理空间发展约束日益增加的新常态背景下,以数字孪生等为代表的数字技术正加快推进城市数字化转型,对城市经济、社会、生态等进行体系重构、流程再造、能力重塑。数字孪生城市成为城市数字化转型的前沿方向和重要实践,背后是转型需求、技术演进、政策引导和产业促进4大驱动力。提出涵盖数字设施、底座平台、场景建设,以及组织机制、标准规范、运营支撑、安全保障体系的数字孪生城市发展框架。在深入分析数字孪生城市认知、技术、模式、安全等4方面挑战的基础上,从分类规划有序布局、坚持需求引领建设场景、强化底座平台赋能、注重数据安全保障与加快产业培育等方面,提出符合我国城市数字化转型发展要求的数字孪生城市规划策略与发展建议。

Under the background of the new normal with increasing constraints on the development of urban resources,environment,and physical space,digital technologies represented by digital twins are accelerating the digital transformation of cities,and carrying out system reconstruction,process reengineering,and capacity reshaping of urban economy,society,and ecology.The digital twin city has become the frontier direction and important practice of urban digital transformation,behind which there are four driving forces:transformation demand,digital technology,policy guidance and industry promotion.It also proposes a digital twin city development framework covering digital facilities,base platforms,scene construction,organizational mechanisms,standards and specifications,operational support,and security systems.On the basis of in-depth analysis of the challenges in four aspects of digital twin cities,this paper puts forward digital twin city planning strategies and development suggestions that meet the requirements of the country's urban digital transformation and development.
