Revealing Stratification Dynamics and Catalytic Renewal Strategies for Ancient City Historic Districts: A Case Study of Sanyi Street in Jingzhou Under the Lens of Urban Catalyst Theory

Abstract

As a significant component of China’s historical and cultural heritage, Sanyi Street in Jingzhou Ancient City has encountered the dual challenges of preservation and development amid the ongoing urbanization process in recent years. Grounded in urban catalyst theory and cumulative layer theory, this study conducts a stratified analysis of the historic district from both spatial and temporal dimensions. It systematically delineates the historical development trajectory and cultural significance of Sanyi Street, while examining its spatial configuration, architectural styles, street scales, and landscape systems. Subsequently, a renewal strategy for the ancient city historic district is formulated through point‑based, linear, and intangible catalysts. This approach effectively reconciles the inherent tension between preservation and development in Sanyi Street, facilitating an integrated coexistence of historical heritage and contemporary urbanity. The findings not only provide a scientific foundation for the protection and renewal of Sanyi Street but also offer valuable references for the conservation and revitalization of other historic districts.
