Objective The Yunzhong-Xizhou mountains ecological network was constructed, and ecologically vulnerable areas within the ecological corridors were accurately identified, in order to provide a scientific basis for formulating ecological conservation and restoration strategies and enhance ecosystem connectivity and stability. Methods Taking the large-scale ecological corridor in the Yunzhong-Xizhou mountains region of Shanxi Province as a case study, the “ecological source-resistance surface-ecological network” framework was adopted to evaluate ecosystem service functions and ecological sensitivity. Morphological spatial pattern analysis (MSPA) was then employed to identify ecological sources. The minimum cumulative resistance (MCR) model was used to construct an ecological resistance surface. Subsequently, circuit theory was applied to extract ecological corridors and identify ecological nodes, ultimately constructing the ecological network for the study area. Results ① A total of 14 ecological sources were identified, with a total area of 1 192.53 km², showing a spatial distribution pattern of relative concentration in the southwest and dispersion in the east. ② A total of 27 ecological corridors were extracted, with a total length of 260.73 km. Additionally, 35 ecological pinch points were extracted, covering 2.71 km². 23 ecological barrier points were identified, occupying 31.82 km². The ecological corridors were concentrated in the central and western regions but dispersed in the northeast. The ecological pinch points and barrier points were scattered along the corridors connecting the ecological sources. ③ The constructed ecological network had an alpha index (circuitry) of 0.71, a beta index (line-point ratio) of 2.08, and a gamma index (connectivity) of 0.82, indicating that the ecological network possessed a complex structure, good connectivity, and strong stability. Conclusion The ecological network constructed based on the evaluation of ecosystem services and ecological sensitivity is accurate and feasible, and it can effectively identify key areas for ecological restoration. The overall strategy for ecological restoration of ecological corridors at the local scale should be ‘protecting ecological sources, restoring ecological pinch points, and removing ecological barriers.’

本研究借助Barrier Mapper工具设置了50,100,150,200,250和300 m 6个搜索半径(图8),识别出23个生态障碍点,覆盖总面积为31.82 km2。从图9可以看出,生态障碍点集中分布在研究区中部平原区,土地利用类型以耕地为主,人类活动干扰大,水土流失问题严重,生态环境敏感,对物种的生存环境构成威胁并阻碍了物种在源地之间的流通。重点提升该区的生态环境质量,能够有效降低生态阻力,改善生态源地之间的景观流通性。
