Research progress on agricultural carbon sequestration: bibliometric analysis based on Citespace

Abstract

To understand the research frontiers and progress of agricultural carbon sequestration, based on the core database of Web of Science, the current research status, research hotspots and trends  were analyzed by bibliometric analysis method. The results show that after 2010, the number of papers published on the agricultural carbon sequestration has exploded. From the perspective of discipline distribution, agricultural carbon sequestration research mainly involves environmental ecology, agronomy, atmospheric science and plant science. From the perspective of international cooperation, China and the United States are the countries with a large number of publications, and the research of American scholars is more closely related to that of other countries, thus occupies a core position in this research field. The Chinese Academy of Sciences, the US Department of Agriculture and the Canadian Agri-Food Research Institute are the largest contributors to the  agricultural carbon sequestration research field, with institutions in Asia and Europe leading this research field. In terms of influence, LAL, R., SMITH, P., and PAUSTIAN, K. are the top three highly cited scholars. Global Change Biology, Science and Nature are the top three most cited journals. From the research content, the basic principles and measures of agricultural carbon sequestration, the evaluation system of agricultural carbon sequestration and the policy standards of agricultural carbon sequestration are the research hotspots. International research hotspots include "soil carbon sequestration", "soil organic matter" and "crop rotation".
