High-intensity land development has led to numerous ecological problems, severely threatening regional sustainable development. Resilience is key to maintaining regional sustainable development. This study focuses on the Taohe River Basin and constructs an ecological resilience evaluation model based on the framework of ecosystem adaptability, ecosystem resistance, and ecosystem recovery from the perspective of resilient ecosystem functions. Using software such as InVEST and Fragstats, the study assesses the spatiotemporal changes in ecological resilience in the Taohe River Basin. Based on the ecological resilience pattern, ecological sources were identified, resistance surfaces were constructed, and ecological corridors were extracted, thereby establishing an ecological resilience security pattern for the Taohe River Basin. During the study period, the level of ecological resilience in the Taohe River Basin showed a gradual upward trend. A total of 33 ecological source areas were identified, accounting for 27.57 % of the total area of the Taohe River Basin. Seventy ecological corridors were identified, with a total length of 6478.63 km and an average length of 92.55 km. Combining the topography, ecological background conditions, and current urban development status of the Taohe River Basin, an ecological security pattern of "two screens, two corridors, five areas, and multiple points" was constructed, along with corresponding optimization suggestions. The research results are of great significance for optimizing spatial layout, maintaining regional ecological security, and promoting regional integrated development. Additionally, they provide new ideas for assessing regional ecological resilience.
