Research on Morphological Resilience and Assessment Methodology in Historic Districts: A Case Study of Jinan Historic Commercial District

Current research on resilience in historic districts remains largely theoretical with limited quantitative methods. This study develops a quantitative assessment framework by integrating Conzenian urban morphology and resilience theory. Through delineating morphological regions and correlating them with resilience attributes, multiple indicators are quantified and integrated to generate morphological resilience zones. Applied to Jinan’s Historic Commercial District, the results reveal a clear spatial distribution of resilience levels—lowest along Weiliu Road, moderate around key intersections and historic areas, and highest in zones with public and well-preserved historic structures, showing an area ratio of approximately 5:8:1 across low, medium, and high resilience levels. The framework supports the classification of management units and targeted resilience strategies, demonstrating practical value for the refined conservation and management of historic districts.
