The implementation of the carbon sequestration function of carbon sinks from typical blue carbon ecosystems (BCEs), such as mangroves and seagrass beds, is one of the natural solutions to mitigate global climate change. Guangdong Province has abundant blue carbon sink resources; a scientific finding on the research progress on carbon sinks in typical BCEs is of great significance for ecosystem protecting and restoring and policy making. In this study, literatures from the Chinese National Knowledge Infrastructure (CNKI) database on carbon sinks related to BECs in Guangdong Province published in the past 20 years were analyzed by using the CiteSpace bibliometrics method from the aspects of research status and development trend, to explore the research hotspots and future research trends in this field. The visualization analysis of article authors, research institutions, keywords, etc., showed that the research development on carbon sinks in BCEs in Guangdong Province can be preliminary divided into three stages: the initial stage (2003—2011), the slow development stage (2012—2016) and the rapid development stage (2017—2023). The results of keyword co-occurrence map and cluster map analysis showed that the relevant researches were mainly focused on carbon storage, mangroves, marine carbon sinks, seagrass beds, biomass, etc, respectively, and the future research hotspots would still be oriented to carbon neutrality and carbon peaking. The study proposed that in the future, researches should be emphasized on the monitoring and accounting methods and the sink-enhancing technologies for carbon sinks in typical BCEs including mangrove forests and seagrass beds in Guangdong Province, and on the construction of a carbon-negative technology system for typical BCEs as well, which will contribute to realizing the synergy between the protection and restoration of BCEs and the enhancement of carbon sequestration and carbon sinks, and will finally achieve carbon neutrality and carbon peak.
