| 中文摘要 |
| 城市作为经济发展和生态治理的核心，增强其韧性水平对实现城市可持续发展具有重要意义. 基于“抵抗力-适应力-恢复力”这3个维度构建城市生态韧性评价指标体系，利用熵值法对2006~2020年长江经济带城市生态韧性进行测度；并运用时空地理加权回归（GTWR）模型探索城市生态韧性驱动机制. 结果表明：①2006~2020年长江经济带城市生态韧性均值总体呈上升态势，并且区域间生态韧性差异显著，下游地区显著优于中游和上游地区. ②长江经济带城市生态韧性呈现出从低等级向高等级演替的规律，直辖市或省会城市作为区域发展的核心极化效应突出，但较低及以下级别生态韧性区仍占较大比例，城市整体生态韧性提升潜力大. ③长江经济带城市生态韧性时空演变特征由多种因素综合驱动并呈现出一定的规律性，其中科技投入、对外开放和经济水平显著促进城市生态韧性的提升. |

| 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. |
