随着城市发展进入新阶段和规划理念的人本主义转向，以空间共享提升城市功能、激发街道等公共空间活力，成为国际主要大都市的共同选择，并在新冠疫情期间取得了积极成效。本文基于美国旧金山市发布的《共享空间手册》，重点介绍旧金山共享空间计划的基本概况、设计指引和操作程序。在此基础上，提出对中国城市公共空间复合利用和精细化治理的3点启示：重视量大面广的城市公共空间的复合利用，把握公共空间利用的法规刚性与引导弹性，搭建可持续的实施机制与治理平台。
As urban development enters a new stage and the humanistic shift of planning concepts，space sharing to enhance urban functions and stimulate the vitality of public spaces such as streets has become a common choice for major international metropolises，and has achieved positive results during the COVID-19 pandemic. This article is based on Shared Spaces Manual released by the City of San Francisco in December 2022，focusing on the basic overview，design guidelines，and operating procedures of the San Francisco Shared Space Plan. On this basis，three enlightenments for the composite utilization and refined governance of urban public space in China are proposed：pay attention to the composite use of urban public spaces，grasp the rigidity of laws and regulations and the flexibility of guidance for the use of public space，and build a sustainable implementation mechanism and governance platform.
