Abstract:Based on the theory of organic renewal, this study constructs a technical framework integrating 'protection–inheritance–activation' for historical and cultural spaces.Using Xiaoshan Congzhu Park in Quanzhou as an example, this paper explores strategies for the organic renewal of urban historical and cultural spaces, aiming to reshape the interactive relationship between these spaces and urban life. By combining methods such as literature review, field research, and case studies, the paper systematically examines the historical context and resource endowments of Xiaoshan Congzhu Park. With the goals of restoring its former glory, rehabilitating the site, serving the community, and showcasing the ancient city, strategies such as protecting historical relics, inheriting cultural heritage, rationally planning spatial layouts, and activating spatial functions were implemented. These efforts effectively unearthed and revitalized historical resources, significantly enhancing the quality of the regional ecological environment and cultural-educational functions. Additionally, the innovation in operational mechanisms and management models have driven the integrated development of local cultural and tourism industries. Finally, the study proposes recommendations such as harmonizing new spatial layouts with the surrounding environment, emphasizing human-centered design principles, and innovating activation and utilization models to sustain site vitality
