Global urbanization process leads to ecological habitat fragmentation and biodiversity reduction. This study investigates the mechanism of multi-functional ecological corridor construction in enhancing urban ecological resilience, taking the ecological restoration project of Chengdu Ring Road Ecological Zone as an example. Using the theory of landscape ecology, the study constructed an ecological resilience assessment model from the three dimensions of ecological source identification, resistance surface construction and corridor identification, combined with the “patch-corridor-substrate” model, to analyze the role of ecological corridors in enhancing the ecological resilience of the city. The results show that the critical area for restoration of Chengdu Ring Road Ecological Zone is 277.77km², of which Jinjiang District accounts for 85.20%; the total length of the critical area for corridor restoration is 416.0717km, and the restoration needs of Jinjiang, Wuhou, and Jinniu Districts account for 81.53% of the total length of the critical area for corridor restoration; The Ecological Priority Development (ELP) scenario, with the shortest length of ecological corridors (9.2498km) and the highest network transmissibility, showed the best ecological resilience. The study confirms that multifunctional ecological corridors significantly enhance urban ecological resilience by improving habitat connectivity, enhancing network structural stability, and improving damage resistance. The ecological network with ecological priority development shows higher connectivity robustness and vulnerability robustness in the face of both random and deliberate attacks. The results of the study provide a scientific basis for the construction of urban ecological security patterns and the enhancement of resilience.
