| 中文摘要 |
| 探讨长江上游岸线（重庆段）生态修复分区及诊断，为区域国土空间生态修复提供科学依据. 采用“敏感-恢复-阻力”（SRP）模型对2010~2023年的长江上游岸线（重庆段）进行生态脆弱性评价，运用形态空间格局分析（MSPA）、最小累积阻力模型（MCR）和电路理论等方法构建生态安全格局，基于生态脆弱性评价和生态安全格局构建进行生态修复分区，并提出诊断策略. 结果表明：①2010~2023年，生态脆弱性指数整体呈上升趋势，中度及以上生态脆弱区占95.86%，高度、重度脆弱区多集中在重庆市主城区和各区县的中心城区所在岸线. ②研究区共识别17处生态源地，面积达155.10 km2；25条生态廊道，总长度达438.46 km；12处生态夹点，集中分布在重庆市主城区所处岸线；39处生态障碍点，多分布在云阳至奉节段. ③生态修复分区可分为重点保护区、自主保护区、重点修复区和生态整治区这4类，并针对不同分区提出诊断策略，可为长江上游生态系统保护与修复提供参考. |

| Exploring the ecological restoration zoning and diagnosis of the territorial space of the upper reaches of the Yangtze River shoreline in the Chongqing section could provide a scientific basis for regional land space ecological restoration. This study used the “sensitivity-resilience-pressure” （SRP） model to evaluate the ecological vulnerability of the upper reaches of the Yangtze River shoreline in the Chongqing section from 2010 to 2023 and used various methods to construct the ecological security pattern， including morphological spatial pattern analysis （MSPA）， minimum cumulative resistance （MCR） model， circuit theory， and others. Based on the ecological vulnerability assessment and ecological security pattern construction， this study carried out the territorial ecological restoration zoning and proposed diagnostic strategies. ① From 2010 to 2023， the ecological vulnerability index showed an overall upward trend， with moderate and above ecological vulnerable areas accounting for 95.86%. Highly and severely vulnerable areas were primarily concentrated in the main urban area of Chongqing and along the shorelines of the central urban areas of districts and counties. ② The study identified 17 ecological sources totaling 155.10 km2 in area， 25 ecological corridors with a total length of 438.46 km， 12 ecological pinch points concentrated in the shoreline of Chongqing's main urban area， and 39 ecological barriers predominantly located in the shoreline from Yunyang to Fengjie section. ③ There were four categories of ecological restoration zoning， including key protection areas， independent protection areas， key restoration areas， and ecological remediation areas. This paper proposed diagnostic strategies for different zones to provide references for the protection and restoration of ecosystems in the upper reaches of the Yangtze River. |
