| 为了解土壤有机碳的研究现状和热点动态，基于文献计量分析，在Web of Science 核心数据库中以土壤有机碳为主题词进行检索，通过筛选将得到的891篇相关高被引论文作为研究数据，利用VOSviewer和Citespace软件对以土壤有机碳为主题词的文献进行定量分析。结果表明：1）高被引文献在2012—2022年间总体呈上下波动状态。2）环境科学、生态学和多学科科学等学科是土壤有机碳研究涉及的主要学科领域，多学科科学逐渐成为研究的主要趋势，在该领域占有重要地位。3）Yakov Kuzyakov和中国科学院是土壤有机碳研究相关领域的主要贡献作者和机构；中国科学院和Yong Sik Ok分别为该研究领域内与其他科研机构和作者之间合作最为密切的机构和作者。 4）通过对关键词和突现词的分析得出，该领域的主要研究热点和发展趋势主要集中在土壤中CO2含量的变化对大气中温室气体含量与气候变化之间的关系、农业土地利用中土壤有机碳封存与固定和热解温度对生物炭影响的相关研究。总体而言，在全球气候变暖的背景下，土壤有机碳的研究仍然是目前研究的热点主题，今后应更加注重不同环境、不同区域间的协同研究，从而进一步探明全球气候变化对土壤有机碳的影响。 |

| Abstract: |
| In order to understand the research status and hotspot trends of soil organic carbon， based on bibliometric analysis， soil organic carbon as the main topic was searched in the core database of Web of science， and 891 relevant highly cited papers were selected as research data. VOSviewer software and Citespace software were used to quantitatively analyze the literature with soil organic carbon as the theme word. The results showed that： 1） The highly cited literature showed an overall fluctuating trend from 2012 to 2022. 2） Environmental science， ecology and multidisciplinary science were the main disciplines involved in soil organic carbon research， and multidisciplinary science had gradually become the main trend of research and occupying an important position in this field. 3） Yakov Kuzyakov and the Chinese Academy of Sciences were the major contributors and institutions in the fields related to soil organic carbon research. The Chinese Academy of Sciences and Yong Sik Ok were the institutions and authors that cooperate most closely with other scientific research institutions and authors in this research field. 4）Through the analysis of keywords and emergent words， the main research hotspots and development trends in this field mainly focused on the relationship between the change of soil carbon dioxide content and atmospheric greenhouse gas content and climate change， soil organic carbon sequestration and fixation in agricultural land use， and the influence of pyrolysis temperature on biochar. In general， in the context of global warming，research soil organic carbon remains a hot topic. In the future， more attention should be paid to the collaborative research between different environments and different regions， so as to further explore the impact of soil organic carbon change on climate change. |
