土地是城市发展的宝贵资源,不能无限扩大,必须在原有土地的基础上充分发挥其潜能,提高土地的使用效率,体现城市更新的价值。加强地下空间建设与地上更新之间的联系有着重大的现实意义,不但能改善中心城区的环境,还可以发挥土地最大的商业价值与效益。在进行中心城地下空间开发和改造时,可将地上地下的交通、商业、市政等多功能整合为统一的、相互联系的整体。本文对北京中心城区3种典型的地下空间逐条分析,提出不同类型地下空间更新利用的迫切需求、原则和方式,从前期策划的视角寻求规划策略。总结为:提前策划分步实施、城市功能的补充和转移、结合现状差异化开发以及关注人的感受以共同打造高质量发展的城市环境。

Land is a precious resource for urban development that cannot be expanded indefinitely. It necessitates the full utilization of its potential on existing land, the enhancement of land use efficiency, and the reflection of the value inherent in urban renewal. Strengthening the connection between underground space construction and above-ground renewal has significant practical significance. It can not only improve the environment of the central city area but also maximize the commercial value and benefits of land. When developing and transforming the underground space of the central city, the transportation, commercial, municipal, and other functions above and below ground should be integrated into a unified, interconnected whole. This article analyzes three typical underground spaces in the central urban area of Beijing, and proposes the urgent needs, principles, and methods for the renewal and utilization of different types of underground spaces, and seeks planning strategies from the perspective of early planning. The summary is to implement step-by-step planning, supplement and transfer urban functions, combine differentiated development with the current situation, and focus on people's feelings to jointly create a high-quality urban environment for sustainable development.
