基于VOSviewer的叶际微生物研究现状可视化分析

VOSviewer-Based Visual Analysis on Research Status of Phyllosphere Microorganisms

通过对国内外叶际微生物研究领域的分析和比较,明确叶际微生物的研究现状和热点,为该领域的进一步研究提供参考。采用文献计量学分析方法,利用可视化分析工具VOSviewer对中国知网收录的114篇文献和Web of Science核心合集数据库收录的521篇文献进行相关分析。叶际微生物相关研究领域的年发文量总体呈现上升趋势,且年平均英文文献数量总体高于中文文献数量,美国、中国和德国的发文量居于前列。其中中国和澳大利亚的合作最为紧密,美国与其他国家的合作最多。研究机构中中国科学院发文量最多,并且与其他研究机构的合作较多。该领域中白志辉(Bai Z H)的发文量最多,且各作者所在团队内部合作较为密切;虽然英文文献中白志辉和金德才(Jin D C)所在团队间有紧密合作,但从整体上看,无论是在中文文献中还是在英文文献中各团队间仍缺乏合作。关于叶际微生物,CNKI和WOS中的文献均对其群落结构和多样性展开了研究,中文文献目前只倾向于探究叶际微生物在植物病害、生物防治和重金属污染方面的作用,但整体研究尚浅,而英文文献则更为广泛且深入地探讨了微生物与植物、微生物和环境之间的关系。研究结果表明,目前关于叶际微生物的研究尚处于起步阶段,叶际微生物群落结构和多样性是该阶段的研究热点和研究方向。

Through the analysis and comparison of domestic and foreign research fields of phyllosphere microorganisms,the research status and hotspots of phyllosphere microorganisms were clarified,and the reference for further research in this field was provided.This paper adopted bibliometric analysis method and the visual analysis tool VOSviewer to conduct correlation analysis on 114 literature included in CNKI and 521 literature included in the Web of Science core collection database.The annual publication volume in the field of phyllosphere microorganisms generally showed an upward trend,and the annual average number of English articles was higher than that of Chinese articles,with the United States,China and Germany ranking at the forefront.Among them,China and Australia cooperated most closely,and the United States collaborated most with other countries.Among research institutions,the Chinese Academy of Sciences published the most papers and cooperated more with other research institutions.Bai Zhihui(Bai Z H)published the most papers in this field,and the teams of the authors cooperated closely.Although there was close cooperation between the teams of Bai ZhiHui and Jin Decai(Jin D C)in the English literature,on the whole,there was still a lack of cooperation between the teams in both Chinese and English literature.As for phyllosphere microorganisms,studies have been carried out on their community structure and diversity,and related papers can be found in CNKI and WOS.At present,the Chinese literature only tends to explore the role of phyllosphere microorganisms in plant diseases,biological control and heavy metal pollution,while the English literature is more extensive and in-depth in discussing the interaction of phyllosphere microorganisms with plants,microorganisms and environment.In summary,the research on phyllosphere microorganisms is in its infancy,and the community structures and diversity of phyllosphere microorganism communities are the research hotspots and directions in this stage.
