Morphological resilience evaluation research on the conservation and renewal of historic districts: A case study on Xijie Historic District, Quanzhou

In recent years, the focus of tangible cultural heritage conservation has gradually shifted from static protection to the stimulation of dynamic vitality and refined guidance. Historic districts frequently encounter various challenges and uncertainties in conservation and renewal practices, including the decay of physical spaces and the adverse impacts of commercial development. Addressing whether existing conservation and renewal models can enable historic districts to sustain their capacity for resistance, adaptation, and transformation constitutes an urgent issue. This study adopts a morphological resilience framework to construct an evaluation system. It takes Xijie Historic District as a case study to identify regions of weak resilience and propose targeted optimization strategies. The findings of the study reveal that: (1) Establishing a multi-level indicator system can systematically assess the resilience level of historical districts. (2) It is possible to enhance integrated resilience and support adaptation to tourism by increasing public facilities, dividing plot series into 1500–2000 m 2 , and upgrading buildings with low quality and value. (3) Advancing a hierarchical conservation strategy of macro-level protection and meso- and micro-level classified renewal contributes to providing a valuable reference for responding to the complex challenges of urban renewal and promoting the refined conservation of heritage.
