Ecosystem restoration and management based on nature-based solutions in China: Research progress and representative practices

Ecosystem restoration, as a core strategy for implementing Nature-based Solutions (NbS), inherently aligns with NbS principles. Despite significant progress in biodiversity conservation and restoration, China still faces risks of ecosystem degradation. To maximize the potential of NbS in China's restoration efforts, it is crucial to develop a framework rooted in NbS principles. However, the application of NbS is hindered by weak theoretical foundations and a lack of comprehensive case studies. This study integrated NbS principles with key theoretical concepts, including sustainable development, socio-ecological systems, ecosystem services, biodiversity, restoration ecology, natural capital, and ecological products, to develop a NbS-based theoretical framework for ecosystem restoration. Drawing on insights from the "Generation Restoration'' report, we synthesized representative practices across various Chinese ecosystems, including farmlands, forests, freshwater, grasslands, oceans, coasts, peatlands and urban areas. Our study provides both a theoretical foundation and practical guidance for integrating NbS into ecosystem restoration, aiming to enhance conservation efforts and promote sustainable development in China.
