[Spatio-temporal Evolution Characteristics and Driving Mechanisms of Urban Ecological Resilience in the Yangtze River Economic Belt].

As key drivers of economic development and ecological governance， cities play a pivotal role in regional development. However， rapid industrialization and urbanization have brought challenges such as ecological degradation and resource shortages. Enhancing urban ecological resilience is crucial to addressing these issues. One effective approach is constructing ecological resilience assessment models. This study develops an urban ecological resilience assessment model for the Yangtze River Economic Belt， focusing on "evolutionary resilience" and based on the "resistance-adaptability-recovery" dimensions. The model assesses urban ecological resilience from 2006 to 2020. Utilizing the geographically and temporally weighted regression （GTWR） model， the study identifies the primary drivers of ecological resilience and examines their mechanisms. Key findings include： ① From 2006 to 2020， the average urban ecological resilience in the Yangtze River Economic Belt increased overall， with significant regional disparities， there was a notably better performance in downstream areas compared with that in the midstream and upstream regions. ② There was a general trend of progression from lower to higher levels of urban ecological resilience， with major cities， including municipalities and provincial capitals， showing strong core polarization effects in regional development. However， many areas still exhibited low or lower levels of resilience， indicating significant room for improvement. ③ The spatiotemporal evolution of urban ecological resilience in the Yangtze River Economic Belt was influenced by multiple factors， with notable contributions from technological investment， foreign trade openness， and economic level.
