基于Web of Science的油菜素甾醇研究态势分析

Analysis of Research Trends in Brassinosteroid Based on Web of Science Database

[目的/意义]为了客观全面地揭示油菜素甾醇研究进展和知识结构,指导科研人员更好地推进领域后续研究。[方法/过程]笔者基于Web of Science数据库,利用引文分析软件CiteSpace系统分析了1970年-2019年油菜素甾醇国际研究文献大数据。[结果/结论](1)自油菜素甾醇被发现以来,研究文献数量总体保持逐年增长的趋势,尤其近10年;全球发文数量最大的国家依次是中国、美国、日本,其中日本理化学研究所和中国科学院是主要研究力量;(2)围绕日本学者形成了5个核心作者群,内部合作紧密,并逐步向外扩散;(3)油菜素甾醇研究可以分为4个阶段:萌芽期(1970年-1990年)、形成期(1991年-2000年)、发展期(2001年-2010年)和成熟期(2011年-2019年);(4)未来研究的重点方向是油菜素甾醇参与逆境胁迫响应的分子机制及其农业应用。

[Purpose/Significance]In order to objectively and comprehensively reveal research progress and knowledge structure of brassinosteroid to guide researchers to better promote the follow-up study. [Method/Process]This paper systematically analyzed the big data of international literature on brassinosteroid from 1970 to 2019 based on Web of Science database by CiteSpace software. [Results/Conclusions](1) Since the discovery of brassinosteroid,the total number of research has been increasing year by year, especially for recent ten years China, the United States and Japan have published the most number of papers, among which, the RIKEN(Japan) and Chinese Academy of Sciences are the main force.(2) There are five core author groups formed around Japanese researchers, and the internal cooperation is close and gradually spreads out.(3) The study of brassinosteroid can be divided into four stages: germination stage(1970-1990), formation stage(1991-2000), development period(2001-2010) and mature stage(2011-2019).(4) The focus of future research is the molecular mechanism of brassinosteroid involved in stress response and its application.
