Abstract
Against the backdrop of rapid urbanization,historic and cultural districts commonly face issues such as spatial decay,functional imbalance,and weakened cultural vitality.Traditional renewal models,predominantly reliant on large-scale reconstruction or static preservation,struggle to address their complexity and sustainability demands.Urban catalyst theory,emphasizing small-scale key interventions to trigger systemic reactions,offers a new pathway for incremental revitalization.Taking the Sanxue Street historic and cultural district in Xi'an as a case study,this article systematically analyzes the district's current problems and catalytic potential from three dimensions—material space,historic heritage,and cultural function—based on a review of the connotations of urban catalyst theory.It constructs a corresponding catalyst factor system and proposes a tripartite renewal strategy of"spatial quality improvement,historical revitalization,and cultural reinterpretation".The aim is to inform sustainable renewal of similar cultural districts in China.关键词
