我国微生物学相关方向研究生论文选题变化分析(1999−2018年)

Research topics in microbiology for graduate students in China(1999–2018)

【背景】当前微生物学研究正处于发展的重要时期,研究生学位论文作为研究生阶段的主要产出,在一定程度上体现了微生物学研究的热点和发展方向,但当前的大多文献计量分析以Web of Science、知网等收录的期刊论文为主,忽略了研究生论文数据库的重要作用。【目的】通过分析我国研究生学位论文的研究选题,为探究我国微生物学相关方向的研究生学位论文的选题热点及变化趋势提供数据支持。【方法】利用文献计量学方法,对1999−2018年收录于中国博硕士学位论文全文数据库的237562篇以微生物为研究主题的论文进行分析。【结果】发现1999−2018年我国微生物学相关的研究生论文总体呈现增长趋势,学位论文发文量排名前三的科研机构是浙江大学、中国科学院大学和南京农业大学。通过关键词网络分析发现,近10年我国微生物学相关研究生论文的研究领域呈现多样化,关键词网络更加密集,研究主要集中于环境、人类医学和动物医学等领域,与国际热点领域基本一致,但基础微生物研究相对不足。近年来备受关注的一些新兴领域如宏基因组、蛋白质组、工程与药物等在研究生论文选题中仍需加强。【结论】文献分析结果为研究生及其导师选题、推动我国微生物学相关的研究生教育的理论研究和实践探索提供了一定参考。

[Background]Microbiology is embracing a crucial period for development.Master’s thesis,as the main output of graduate students,reflects the research trend in this discipline.However,previous bibliometric analysis mainly focused on papers from Web of Science and China National Knowledge Infrastructure(CNKI)rather than the theses from master’s thesis databases.[Objective]Our aim in this paper is to explore the research approach and hotspots of postgraduate dissertations in the field of microbiology in China.[Methods]We analyzed 237562 master’s theses on microbiology in China Doctoral Dissertations/Master’s Theses Full-text Database(CDMD)from 1999 to 2018 with the bibliometrics method.[Results]We found that the total number of microbiology-related theses in China showed an increasing trend from 1999 to 2018,and Zhejiang University,University of Chinese Academy of Sciences,and Nanjing Agricultural University ranked the top three in the number of published theses.According to the network analysis of keywords,research fields of postgraduates in China are diversified in the 10 years.The research hotspots in microbiology,such as environment,animal medicine,and human medicine,are also international research focuses,but basic microbiology is yet to be further emphasized.Some emerging topics such as metagenomics,proteomics and engineering,and medicine should be highlighted among postgraduates.[Conclusion]The result is expected to serve as a reference for topic selection by graduate students and their supervisors,and education and practice of postgraduates on microbiology in China.
