土壤碳库在全球碳循环和生态系统健康维持方面具有关键作用。为了解土壤碳库的研究趋势和热点，本文基于2014-2023年中国知网和Web of Science数据库发表的8659篇论文，利用VOSviewer和CiteSpace可视化工具，分析了有关土壤碳库研究的论文发表数量、被引频次、研究机构、主要作者和研究热点等。结果表明:近十年间国内外关于土壤碳库的研究论文发文量呈现上升趋势，年均发文量为492。95篇;被引频次最高的中文文献为《土壤碳库构成研究进展》，被引次数为265次，被引频次最高的英文文献为"Total Carbon and Nitrogen in the Soils of the World"，频次为2480次;中英文文献的主要贡献者为我国的科研机构和人员;研究热点聚焦在土壤碳库的组分、稳定性和影响因素等方面;研究趋势逐渐从碳组分研究转向碳库稳定性控制和与生态系统功能的关系探讨。未来研究应重点关注碳库稳定性调控、碳中和策略以及全球变化对碳库的影响。期望本文能够为土壤碳库的研究提供借鉴与参考。
Visual Analysis of Soil Carbon Pool Research from 2014 to 2023 Based on VOSviewer and CiteSpace
Soil carbon pools plays a crucial role in the global carbon cycle and the maintenance of ecosystem health.To understand the research trends and hotspots related to soil carbon pools,in this paper we analyzed 8659 relevant articles published from 2014 to 2023 in the China National Knowledge Infrastructure(CNKI)and Web of Science databases by utilizing the visualization tools VOSviewer and CiteSpace.The results indicated that the volume of research papers on soil carbon pools has shown an increasing trend over the past decade,with an average annual publication rate of 492.95 articles.The most cited Chinese paper was titled"Research Prog-ress on the Composition of Soil Carbon Pools"with 265 citations,while the most cited English paper was"Total Carbon and Nitrogen in the Soils of the World"with 2480 citations.The primary contributors to both Chinese and English literature were research institutions and personnel from our country.The research hot spots focued on the components,stability,and influencing factors of soil carbon pools.The trend in research was shifting from studying carbon components to exploring the control of carbon pool stability and its relation-ship with ecosystem functions.Future studies should prioritize the regulation of carbon pool stability,carbon neutrality strategies,and the impact of global changes on carbon pools.It is hoped that this paper will provide references and insights for further research on soil carbon pools.
