Abstract: In order to understand the frontiers and progress of research on soil carbon(C) sequestration at home and abroad, the core database in Web of Science (WOS) and the journal database in China National Knowledge Infrastructure (CNKI) were taken as the data sources. Using bibliometric analysis method and CiteSpace software, the research results on soil C sequestration were summarized. The number of publications on soil C sequestration research at home and abroad was generally on the rise, especially in recent years. The number of publications and the influence of published journals in the United States were much higher than those in China. From the perspective of international cooperation level, China and the United States had the closest cooperation and made the greatest contribution to this research field. Among research institutions worldwide, the Chinese Academy of Sciences, Ohio State University and the United States Department of Agriculture Agricultural Research Institute had the greatest influence, and the domestic institutions including Research Center for Eco-Environmental Sciences of Chinese Academy of Sciences, Nanjing Agricultural University and Institute of Soil Science of Chinese Academy of Sciences had the strong resesrch capabilities. The main international journals on soil C sequestration research included Agriculture Ecosystems & Environment, Soil & Tillage Research, and Global Change Biology, and the main domestic journals included Acta Ecologica Sinica, Ecology and Environmental Sciences and Chinese Journal of Applied Ecology. Environmental Science, Soil Science and Ecology were the top 3 disciplines of international research on soil C sequestration. And the domestic research disciplines on soil C sequestration mainly focuseds on agronomy and forestry. In terms of research hotspots and cutting-edge trends, the main international research hotspots were “organic matter” and “nitrogen”. The frontiers of research were greenhouse gas emission and nitrous oxide emission. Soil organic C and C sequestration were the most important research hotspots in China, and soil microbial community structure was the new research leading edge.
