基于豹猫生态需求的深圳坪山区绿地生态网络构建与优化OA

[Objective]This study focused on the leopard cat(Prionailurus bengalensis)as the focal species to identify potential ecological corridors in Pingshan District,Shenzhen,analyze their spatial characteristics and relationships with surrounding land-use types,and optimize the regional green space ecological network for biodiversity conservation and ecological restoration planning.[Method]An integrated MSPA-Conefor-MCR model was used to identify key ecological sources and potential ecological corridors for the leopard cat.Blueway and greenway networks were then incorporated to construct a resilient and efficient green space ecological network.[Result]1)MSPA identified seven landscape types.Core areas in the southern mountainous forests accounted for nearly half of the study area,providing stable habitats for leopard cats,whereas bridge areas and perforation zones in the central and northern parts were more vulnerable to disturbance and required ecological restoration.2)A total of 30 key ecological sources were identified.Large ecological sources in the southern and western parts showed high connectivity and could serve as core habitats,while severe fragmentation caused by urban expansion in the central and northern parts restricted leopard cat movement.3)Low-resistance areas in the south,characterized by high vegetation cover and low human disturbance,provided suitable habitats.In contrast,dense construction land,rivers,and roads in the central and northern parts significantly increased landscape resistance.4)A total of 39 potential ecological corridors were identified and further optimized into 11 ecological corridors by integrating the blueway and greenway networks.[Conclusion]The optimized green space ecological network effectively enhanced connectivity between the southern core ecological sources and isolated patches in the central and northern parts of Pingshan District,providing a scientific basis for regional ecological restoration and biodiversity conservation.
