Abstract: Objective The strategic deployment of Nature-based Solutions(NbS) is emerging as one of the promising methods for addressing climate change worldwide. Reviewing the research progress of carbon sequestration and carbon sink through urban green infrastructure in the context of NbS holds pragmatic significance, as it contributes to fostering the sustainable development of urban ecosystem.Methods Based on the Web of Science Core database, this research employs bibliometric methods to conduct a comparative analysis of relevant research literature. The aim is to summarize the current state of research development,international collaborations, thematic hotspots, and frontier trends.Results Over the past decade, there has been significant research interest in NbS for carbon sequestration and carbon sink increase through urban green infrastructure, especially in the USA, China, and several European countries, and a close and extensive research collaboration network has been established. As to the type of literature, research literature occupies a dominant position relative to review literature, mostly employing quantitative methods to assess the carbon sink benefits of urban green infrastructure at local and urban scales. Qualitative methods, in turn, prove conducive to harmonizing the needs of multiple stakeholders and important for supporting urban planning decisions. Thematic hotspots include exploring the quantitative method, influencing mechanism and optimal layout of carbon sequestration and carbon sink increase through urban green infrastructure, and promoting the mainstreaming of Nb S in urban planning through establishing a clear framework.Conclusion Future research should consider the dual benefits of both direct carbon sequestration and indirect emissions reduction, emphasize the synergistic development of carbon sink potential and other ecosystem service functions, and further expand the scale and benefits of green infrastructure as a Nb S in urban ecosystems.
