Abstract: Forest carbon sequestration play an important role in addressing climate change and are an inevitable choice for achieving carbon neutrality under the "double carbon"(peak carbon dioxide emission and carbon neutrality). To explore the development history, research hotspots and future research trends of forest carbon sequestration, this paper selects 12 216 and 456 papers related to the topic of forest carbon sinks based on Web of Science database and China National Knowledge Infrastructure (CNKI) database, respectively, for analysis. The CiteSpace software was used to identify the countries, institutions, authors, and journals with the most output of forest carbon sequestration research. Visualization methods were used to identify high-frequency keywords, hotspots and research frontiers in the field of forest carbon sequestration. The results showed that the United States is currently the country with the most research on forest carbon sequestration, but China's publication rate has increased rapidly in recent years, and the international influence has also increased. The research of forest carbon sinks is carried out more from the perspective of environmental science and ecology, but less from the aspect of economics. The research in the field of forest carbon sequestration in China has mainly gone through four stages: beginning, development, decline, and explosion. Climate change, influenced by the "double carbon" strategy, started to explode in 2020 and became a new research field of forest carbon sequestration. In the future, Chinese can further focus on the interdisciplinary integration of forest carbon sequestration, deeply explore the potential and spatial effects of forest carbon sequestration, establish a sound forest carbon sequestration trading market, and promote the realization of "double carbon" goal.
