Study on the Renewal of Public Space in Dual-Aged Communities under the Concept of Complete Community: A Case of Shigang Community in Guangzhou

With the development of China's urbanization process, in recent years, the development of cities has shifted from the incremental expansion mode of high-speed growth to the development strategy of stock renewal. At the same time, with the accelerated pace of aging and social problems, the urban community renewal represented by “Dual-aged communities”, i.e., old communities with seriously aging residents, has become a prominent challenge for sustainable urban development. The traditional urban renewal model often focuses on macro-intervention, using a “top-down” approach to update the current situation of the community to a certain extent, however, such a renewal model is difficult to meet the needs of the elderly for physical space renovation, spatial aging adaptability design, reshaping of cultural core and transformation of community renewal and community management in the context of the dual-aged community. However, in the context of dual-elderly communities, it is difficult to meet the needs of the elderly for material space transformation, ageing-friendly design, cultural core reshaping and community management mode. Based on the current context, the study introduces the concept of complete community, emphasizing the wholeness and comprehensiveness of the community, and aims to explore the systematic strategies and methods to improve the public space of the community by emphasizing the systematic theoretical analysis and practical research on the three dimensions of hardware, software and spirit. The study firstly discusses the origin and development of complete community, summarizes the guiding significance of the theory of complete community for dual-aged community renewal in China, and analyzes urban community renewal cases under similar concepts in order to reflect their suitability for the research object and serve as a comparison group for the evaluation system later. Secondly, the construction of the fuzzy comprehensive evaluation system is completed by sorting out the three dimensions and five main influencing elements of the public space of complete community, determining fifteen specific indexes and the specific weights of each index, and establishing the quantitative evaluation criteria corresponding to each index through the sorting out of the relevant contents. After that, through the specific and detailed research on Shigang community, we sort out the specific conditions and problems in various aspects, and make a comprehensive evaluation of the research results, and derive the evaluation results to analyze the key problems. At the same time, based on the previous theoretical research, we formulate the principles, objectives and strategies of dual-aged community renewal under the concept of complete community, determine six basic renewal strategies under three dimensions, summarize the specific renewal methods to form a complete system, and form a renewal method that can provide theoretical references and practical guidance for the renewal of other similar communities. Finally, by integrating the research content and evaluation results, the public space of Shigang community renewal design is targeted to optimize the spatial layout and environmental quality, improve the spatial level of the community intelligence services mechanism to promote the role of the elderly care and humanistic compensation, and summarize the method of public space renewal of the complete community at the design level, to provide the design level reference for the similar research.
