The Renewal Strategy of Public Space in Traditional Kaifong Community Based on the Concept of Community Building----A Case Study of Nanhuaxi Area in Guangzhou

In the field of urban regeneration, community renewal has gradually become the focus of attention, and its mode has also evolved from the traditional large-scale demolition and construction to the transformation focusing on human factors. Especially for the traditional kaifong community in Guangzhou, the value of its historical features and the importance of its regional characteristics and culture to the urban space are becoming more and more prominent. Behind this trend is a renewed awareness of the value of traditional kaifong communities and the need for sustainable urban development. In this transition, the concept of community building has played a positive role by emphasizing the needs and participation of community residents, focusing on the enhancement of the value of physical space, and promoting the advantages of local resources. Based on the field of urban design, this thesis selects traditional kaifong community as the research object, and applies the research methods of literature research, field research and case study to construct the design strategy adapted to the public space renewal of traditional kaifong community. Firstly, I systematically review the development history of community regeneration at home and abroad, discuss the current situation and shortcomings of the research on the regeneration of traditional kaifong community, make clear that there are problems such as low quality of life, lack of humanistic care, weakening of the history and culture of the streets and alleys, and insufficient community participation, etc., and elucidate the suitability of the concept of community building applied to the regeneration of traditional kaifong community, so as to provide support for the construction of theoretical system for the design strategy. Next, I summarize the conceptual achievements of community building, analyse the background differences in community building practices at home and abroad, and draw on the successful experiences of case studies to build practical approaches for design strategies. Specifically, focusing on improving residents' needs, preserving and developing neighbourhood history and culture, and promoting multi party participatory mechanisms, I am committed to excavating and cultivating the neighborhood's street and alley characteristics, designing and creating public spaces, encouraging and supporting residents' participatory design, and striving to improve the humanistic care and quality of the neighbourhood, which, through the demonstration of the examples, is aimed at facilitating the sustainable development of the traditional kaifong community. Finally, I choose Nanhuaxi Area in Haizhu District of Guangzhou to conduct research and design, in-depth understanding of the residents' behavioral characteristics and lifestyles, the area's historical and cultural development and governance methods, sums up the difficulties of public space creation, and explores the use of renewal strategies under community building in the public space of traditional kaifong communities, with the theme of kaifong characteristics and water town style. The innovation of this thesis is based on the methodological system of community building, collating the design strategies in community building at home and abroad, and summarizing the renewal strategies applicable to traditional kaifong communities in China through case studies. The research results of this thesis will provide useful references and lessons for community renewal in the field of urban design.
