【摘要】 生态文明建设是中华民族永续发展的千年大计。国家生态廊道构建作为丰富物种多样性和生态环境保护的重要手段，有助于实现中国式现代化与生态文明建设。从国际视野出发，立足当前国际生态廊道建设经验，以聚焦生物多样性、打破行政边界、促进多主体协同、实施还荒工程和深化国际合作为导向，提出生境、系统、治理、工程和共同体五大理念。在中国情景下，探讨当前国内生态廊道建设在理论、政策及区域尺度的生态廊道建设实践，试图发现其中的问题并作出反思，以提出国家生态廊道建设理论与实践路径。未来，我国在（大尺度）国家生态廊道构建时，要关注典型性、代表性目标物种并构建多尺度嵌套生态廊道，不断强化基础理论、方法与技术研究，总结城市与农村生态廊道的建设经验，探索多模式化区域发展道路，形成良性可持续补偿机制，建立政学社多方合作机制，推动生态系统可持续发展。更多还原

【Abstract】 Ecological civilization construction is a millennium plan for the sustainable development of the Chinese nation. As an important means to enrich species diversity and protect the ecological environment, the construction of national ecological corridors contributes to the realization of Chinese-style modernization and ecological civilization.From an international perspective, and based on current international experiences in ecological corridor construction,this study proposes five core concepts-habitat, system, governance, engineering, and community-guided by a focus on biodiversity, breaking administrative boundaries, promoting multi-stakeholder collaboration, implementing rewilding projects, and deepening international cooperation. Within the Chinese context, it explores domestic practices in ecological corridor construction at theoretical, policy, and regional scales, identifies existing problems, and offers reflections to propose theoretical and practical pathways for national ecological corridor construction. In the future,China should prioritize typical and representative target species in the construction of(large-scale) national ecological corridors, develop multi-scale nested ecological corridors, strengthen fundamental theoretical, methodological, and technological research, summarize experiences from urban and rural ecological corridor construction, explore diversified regional development models, establish sustainable compensation mechanisms, and foster multi-stakeholder collaboration among government, academia, and society to promote the sustainable development of ecosystems.更多还原
