Abstract: The spatial pattern of urban historical spaces embodies morphological characteristics of internal and external integration, layered features of historical continuity, and cultural characteristics of unity between the surface and essence. It serves as a structural clue for understanding the overall spatial relationships, evolutionary trajectories, and cultural connotations of cities. Additionally, it functions as a spatial carrier for telling the overall narrative of urban culture and systematically presenting local stories. In response to the widespread issues of increasing spatial disorder and fragmented cultural lineages in urban historical environments, this study takes Yongyang Ancient City in Yongtai County, Fuzhou City, Fujian Province as a typical case and introduces spatial narrative theory. By employing three spatial narrative elements: space, time, and event-a methodological system for analyzing the spatial characteristics of historical cities is constructed. This approach reveals the multi-dimensional narrative features of Yongyang Ancient City, including its hierarchical spatial connectivity, clearly defined temporal continuity, and diverse historical events. Furthermore, spatial protection and pattern reconstruction strategies are proposed from three aspects: thematic concept, structural organization, and scene creation, aiming to provide methodological guidance and case references for the modern inheritance of historical urban spaces.
