Ecological Resilience and Urban Health: A Global Analysis of Research Hotspots and Trends in Nature-Based Solutions

With rapid urbanization and increasing climate risks, cities are facing complex challenges related to environmental degradation and public health. This study conducts a bibliometric analysis of 1555 publications from the Web of Science Core Collection (2000–2025), using CiteSpace and VOSviewer to map global research trends, hotspots, and thematic evolution in the field of NbS and urban health. Results show that research interest in NbS has significantly accelerated since 2020, with Europe leading in publication output and international collaboration. Keyword analysis reveals that early studies focused on ecosystem services and climate adaptation, while recent trends emphasize governance, public participation, and environmental justice. The study also constructs a knowledge framework that illustrates how NbS contributes to urban heat mitigation, carbon management, health co-benefits, and resilience governance. This research provides a comprehensive overview of the NbS field and offers theoretical insights and empirical references for integrating NbS into urban planning, health strategies, and environmental governance, with practical relevance for cities worldwide.
