Abstract: This study surveyed the literature on grassland carbon sink in core journals accessed through Web of Science from 2010 to 2019 using CiteSpace software to identify any apparent trends and to identify the sphere of influence of existing research of different countries, institutions, journals and individuals. It was found that with respect to global grassland carbon sink, China ranks first, followed by the United States and Germany. In terms of international cooperation, the UK contributes the most, and other countries need to strengthen cooperation and share results. The institution with the largest number of papers is the Chinese Academy of Sciences, far exceeding other institutions. The journal ‘Global Change Biology’ is a clear leader in the number of citations and has a great influence in academia. German scholar Klaus Butterbach-Bahl is the most prolific author and has made a great contribution to the field, but the cooperation between other authors needs to be strengthened. An analysis of hot topics and research frontiers indicates a need to strengthen the effort invested in comprehensive assessment of grassland carbon balance, enhance the sophistication of research methods, and expand research volume.
