基于CiteSpace的草原碳汇研究的知识图谱分析

为全面深入了解草原碳汇相关研究在全球的现状和发展趋势,客观反映相关研究国家、机构、期刊、研究者的科研动向和影响力,采用Web of Science核心合集数据库中2010-2019年收录的有关草原碳汇研究的相关文献,基于CiteSpace软件进行可视化分析。结果表明:关于草原碳汇全球发文量,中国居榜首,美国和德国其次,国际合作方面,英国贡献最大,其他国家需加强合作和成果分享。发文量最多的机构为中国科学院,远超其他机构。《Global Change Biology》期刊在被引次数方面优势明显,在学术界有较大影响力。国外学者Butterbach-Bahl K发表相关文献数量最多,为领域作出较大贡献,其他作者之间合作强度还需加强。综合分析热点和前沿,提出了需加强对草原碳平衡的综合评估,丰富研究方法,扩大研究内容。

Knowledge mapping analysis of grassland carbon sink research based on CiteSpace

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.
