Scientifically evaluating regional ecological resilience under various scenarios is crucial for mitigating ecological risks. This study focuses on selected urban areas in the upper Yangtze River basin and establishes a multi-scale assessment model (mesh and sub-basin) for watershed ecological resilience based on resistance, adaptability, and recovery metrics. The spatial distribution of ecological resilience in 2020 was analyzed at both scales. The study also simulated land use and watershed ecological resilience in 2030 under different scenarios (natural development, urban development, cultivated land protection, and ecological protection) using the MCCA model. Key findings include: 1.Land Use Comparison: In 2020, land use differed significantly from the four projected scenarios for 2030. Arable land and forests remained predominant in all scenarios. 2.Ecological Resilience in 2020: The basin’s overall ecological resilience was moderate, with low-resilience areas accounting for 24.6% at the mesh scale and 14.5% at the sub-basin scale, mainly in western Chongqing and northern Jingzhou. 3.Future Projections for 2030: By 2030, ecological resilience showed significant local variations under the four scenarios at both scales. The ecological protection scenario had the highest resilience, with high-resilience areas at 41.3% (mesh) and 30.7% (sub-basin); the urban development scenario had the lowest resilience, with low-resilience areas at 14.4% (mesh) and 32.5% (sub-basin). These findings provide evidence for maintaining ecological balance and protecting vulnerable areas in the Yangtze River basin. The methods used can help decision-makers implement effective ecological protection strategies, mitigating future ecological risks.
