| 大型水利工程建设与高敏感生态区保护的协调是区域可持续发展的核心难题。为定量评估引大济岷工程对长江上游生态屏障的潜在扰动，本研究以工程沿线11个行政区为评估单元，叠加保护地图层，耦合形态学空间格局分析（MSPA）、最小累积阻力（MCR）模型与电路理论，构建“现状评估—扰动模拟—优化对策”的全流程评估框架，并利用地理探测器模型量化解析阻力空间分异的驱动机制。本研究在工程前期阶段开展扰动模拟与修复效能预判，并针对高山峡谷向平原过渡的复杂景观特征，制定了基于网络连通性恢复率的“源地扩容+靶向修复”耦合优化方案。研究表明：①区域生态阻力由土地利用类型（x1）主导，其与人口密度（x7）的交互解释力形成了阻力分异的核心机制；②工程建设产生的“截断效应”导致网络拓扑指标虚高与实质功能退化解耦，整体连通性指数（IIC）与可能连通性指数（PC）分别下降36.67%和26.00%，并在工程沿线产生12个关键生态断裂点；③实施优化方案后，网络物理断裂点由12处减少至3处，IIC与PC功能恢复率均在75%以上。结果证实，靶向修复可抵消重大线性工程的物理阻隔。建议将研究识别出的154个源地及7项修复工程纳入沿线行政区国土空间规划红线，实现跨区域生态连通性的协同管控。 |

| Balancing large-scale water conservancy construction with the protection of highly sensitive ecological zones is a pivotal challenge for achieving regional sustainable development. To quantitatively assess the potential disturbance of the Yin-da-ji-min Project on the upper Yangtze River ecological barrier, this study takes 11 administrative units (counties, cities, and districts) along the project line as assessment units, overlays protected area layers, couples MSPA, MCR models, and circuit theory to construct a full-process assessment framework of “status quo assessment – disturbance simulation – optimization strategies”. The geographic detector model is used to quantify the driving mechanisms of spatial differentiation in resistance. This study conducts disturbance simulation and restoration efficacy prediction in the pre-construction phase, and develops a coupled “source expansion + targeted restoration” optimization scheme based on network connectivity recovery rates, tailored to the complex landscape characteristics of the transition from alpine canyon to plain. The results indicate that: ① Regional ecological resistance is primarily dominated by land use type (x1), and its interaction with population density (x7) constitutes the core mechanism for spatial differentiation of resistance. ② The “cutoff effect” caused by the project decouples inflated topological indicators from actual functional degradation. The Integral Index of Connectivity (IIC) and Probability of Connectivity (PC) decrease by 36.67% and 26.00%, respectively, with 12 key ecological fracture points emerging along the project route. ③ Implementation of the “source expansion + targeted restoration” scheme can effectively recover over 75% of the functional loss, with the number of physical fracture points reduced from 12 to 3. The results confirm that targeted restoration can offset the physical barrier effect of major linear projects. It is recommended that the 154 source areas and seven restoration projects identified in this study be incorporated into the territorial spatial planning red lines of the administrative districts along the route, so as to achieve coordinated cross-regional ecological connectivity management. |
