摘　　要：在经济增长和人口增加的双重压力下,生态系统服务供给和消耗之间的地理空间分离现象日益突显,凸显了对精细化生态管理的迫切需求,然而传统的保护区划定方法未能充分考虑生态系统服务的动态性和复杂性。聚焦于生态系统服务的流动性及其距离衰减特征,通过应用复杂网络分析,构建了一个基于生态系统服务供应能力的生态保护区划定框架。以湖北省为研究案例,面向城市生态系统服务功能的供需调控,结合生态系统服务流构建了生态系统服务可供给网络,并运用复杂网络结构分析与聚类算法,有效识别了关键的生态管理区域。结果表明,湖北省的生态服务网络呈现出多层次复杂结构,尤其是在空间分布上,各区域节点的服务供给能力和控制作用表现出显著差异性,突显了生态服务供给与需求之间的复杂交互关系。服务供给呈“西高东低”,服务需求则集中在中部城市化水平高的区域,网络中存在的不均衡、关键节点分布不均匀以及连通性和稳定性有待提升等问题亟待解决,尤其是中部地区的低连通性,可能对生态服务的流动性和效率构成限制。在此基础上,划定了生态系统服务优先保护格局分区和整体性的指导框架,将湖北省划分为生态保护区、源地连通区、保育提升区、人地协调区和生态恢复区。总的来说,本研究提出的方法不仅揭示了区域内生态系统服务的空间流动模式,还实现了生态系统服务可供给网络的量化评估,研究结果为湖北省提供了生态保护与资源配置的科学依据,并为跨区域生态资源管理和制定可持续的生态平衡策略提供了一个可实施的工作路径和政策参考。Under the dual pressures of robust economic growth and a burgeoning population,the geographical disjunction between the supply and the consumption of ecosystem services has become increasingly accentuated.This divergence underscores the urgent necessity for more refined and precise ecological management strategies.Traditional methodologies employed for delineating protected areas have not sufficiently addressed the dynamic and intricate nature of ecosystem services.This study places a significant emphasis on the mobility of ecosystem services and explores their distance decay characteristics.By harnessing the capabilities of complex network analysis,a robust framework for delineating ecological protection areas based on the supply capacity of ecosystem services has been meticulously developed.Using Hubei Province as a comprehensive case study,this research meticulously focuses on the regulation of urban ecosystem service functions and integrates ecosystem service flows to construct an extensive and comprehensive supply network.Employing sophisticated network structure analysis and advanced clustering algorithms,the study effectively pinpoints crucial areas requiring stringent ecological management.The results from this detailed analysis reveal that the ecosystem service network in Hubei Province exhibits a complex,multi-layered structure,characterized by significant variability in service supply capacity and control functions across diverse spatial nodes.This intricate structure notably highlights the complex interactions between service supply and demand.More specifically,the provision of ecosystem services is notably higher in the western regions of the province and markedly lower in the eastern regions,while the demand for these services is predominantly concentrated in the highly urbanized central regions.The network is characterized by issues such as pronounced imbalances,an uneven distribution of pivotal nodes,and challenges related to connectivity and stability.In particular,the low connectivity observed i
