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.
