The discovery of the ancient port site of Shuomen in Wenzhou in 2022 makes the city image of "a millennium commercial port and a happy Wenzhou" more specific. However, as an immovable historical site, it will inevitably become an uncertain factor affecting the fragmentation of modern urban space. Therefore, it is of great practical significance to discuss the harmonious coexistence of modern cities and historical sites. The "tuber" theory shows a network structure with adaptability and flexibility, and its principles of connection, heterogeneity and diversity provide various strategic guidance for the effective connection between the two. By increasing the connectivity with surrounding plots, enriching the heterogeneity of the self connotation of historical relics, showcasing the symbiosis of urban culture and the diversity of historical narratives, the Shuomen Ancient Port Site can be harmoniously incorporated into the urban space of Wenzhou, thereby providing blocky urban space while reducing fragmented urban landscapes, ultimately improving residents'' quality of life, continuing urban cultural memory The purpose is to enhance the attractiveness of the city both internally and externally, strengthen the dissemination of Wenzhou culture and image, and better tell the story of Wenzhou.
