Abstract: Chengdu, China, is endowed with abundant ancient and famous trees as well as historical habitats, which are crucial for sustaining urban biodiversity and cultural continuity. This study focuses on the historical habitats along the Second Ring Road and develops a comprehensive evaluation system across five dimensions: ancient and famous trees, species diversity, historical habitat quality, historical habitat health, and historical-cultural value. Twelve representative historical habitats were analyzed using fishnet analysis, image segmentation, and plant diversity surveys to characterize biodiversity patterns and develop strategies for optimizing urban biodiversity conservation and sustainable habitat management. Results indicate: (1) significant variation among historical habitat types, with Huanhuaxi Park achieving the highest overall quality; (2) except in park habitats, comprehensive quality shows no significant correlation with the density of ancient and famous trees, while habitat size exerts a strong influence; (3) the evaluation index system still requires refinement. This research provides practical guidance for the conservation of ancient trees and the sustainable management of historical habitats. At the theoretical level, it underscores the relevance of an “ecology–society–culture” framework, revealing how historical habitats simultaneously sustain ecological functions, support social practices, and embody cultural expression. Overall, the study offers a new perspective for integrating urban biodiversity conservation with cultural heritage protection.
