摘要：
生态网络研究对于现代保护生物学至关重要，可应对栖息地破碎化和生物多样性丧失问题，尤其是在复杂区域。这些网络包含廊道、源地和节点，是物种移动与生态系统功能的关键。本文提出 Periphery Analysis Model（PAM，边缘分析模型），作为研究此类网络边缘的新方法，重点关注边缘节点在环境变化响应和网络恢复力中的作用。PAM 借鉴图论、复杂网络分析和景观生态学，采用 Periphery Uniqueness Index（PuI，边缘独特性指数）和 Periphery Balance Index（PbI，边缘平衡指数）来衡量边缘节点的属性与平衡。它还提供若干派生指数，以详细理解边缘的影响。通过揭示边缘的定义性特征，PAM 增进了对生态网络结构特征的认识，为生物多样性、连通性和生态系统健康提供洞见。该研究鼓励将 PAM 纳入保护策略，以便在环境挑战中为生态系统保护政策提供依据。
英文摘要：
The study of ecological networks is crucial for modern conservation biology, addressing habitat fragmentation and biodiversity loss, especially in complex regions. These networks, including corridors, sources, and nodes, are key for species movement and ecosystem functioning. The Periphery Analysis Model (PAM) is introduced as a new approach to study the periphery of these networks, focusing on peripheral nodes' role in environmental change response and network resilience. PAM, drawing from graph theory, complex network analysis, and landscape ecology, uses the Periphery Uniqueness Index (PuI) and the Periphery Balance Index (PbI) to measure peripheral nodes' attributes and balance. It also offers derived indices for a detailed understanding of the periphery's influence. By revealing the periphery's defining characteristics, PAM enhances knowledge of ecological networks' structural features, providing insights for biodiversity, connectivity, and ecosystem health. The research encourages integrating PAM into conservation strategies to inform policy for ecosystem preservation amid environmental challenges.
