Exploration on Micro-renewal of Urban Public Space Based on Community Building

As urban construction shifts from the incremental to the stock stage, the progressive micro-renewal has become the main mode of urban renewal and reconstruction. The partial renewal mode, which takes public participation as the basis, and micro community and public space facilities as the targets, has become a new way to stimulate the vitality of cities and improve the quality of the built-up urban public space. Taking the projects in Beijing and Shanghai as examples, this paper discusses the development background of urban micro-renewal, and expounds the multiple meanings of urban public space in the context of micro-renewal. On this basis, it summarizes the micro-renewal approaches of urban public space based on community building, which are the integration of marginal space and the choice of catalyst mode, the excavation of the authenticity of the historical context of the site, the protection of the social lifestyle of community residents, and the establishment of the open communication platform of multi-party collaboration and the responsibility planner system.
