Research on the Renovation Design of Old Industrial Areas from the Perspective of Urban Regeneration

Under the perspective of urban regeneration, the transformation of old industrial areas has gradually shifted from physical space renewal to comprehensive regeneration integrating space, industry, culture and ecology. This study constructs a technical path of “diagnosis-evaluation-generation” and conducts quantitative analysis on an old industrial area through models such as accessibility index, functional mixing degree and vitality fluctuation. The results show that the accessibility index of typical nodes is between 12.84 and 31.87, and the spatial fragmentation is significant; the functional mixing degree of some nodes is only 0.42, reflecting a serious lack of industry and services. On this basis, the potential of 6 areas is evaluated by using the AHP-entropy method. Among them, the comprehensive scores of S4 and S2 reached 0.73 and 0.68, respectively, and were identified as the areas with the most regeneration value. The study further constructs spatial optimization, functional configuration and ecological pattern models and proposes a systematic renewal path. The research results provide a quantitative basis for accurately identifying problems and scientifically formulating regeneration strategies for old industrial areas.
