基于Web of Science的苔藓植物研究文献计量分析

Bibliometric Analysis of Bryophyte Research Based on Data from Web of Science

为了解全球苔藓植物的研究现状,从文献计量学视角出发,以Web of Science数据库为数据源检索了1965~2017年间与苔藓植物研究相关的文献,采用文献计量法定量分析了苔藓植物研究文献的年度发文量、国家、作者、研究机构、期刊以及学科分布等指标。结果表明;1965~2017年间,全球有关苔藓植物的研究文献24784篇,其研究总体上呈明显上升趋势,在经过发展相对缓慢的起步阶段(1965-1989年)后,出现了大量成果发表的快速发展阶段(1990~2017年),预计未来在相关研究领域仍会有大量成果发表。全球发表相关文献数最多的国家依次为美国、德国和英国,而我国全球排名第5,这表明我国在苔藓植物研究方面具有较高的国际影响力。日本、波兰和德国的学者分别在苔藓植物化学、分类学以及分子系统学等方面发表了较多文献,我国部分学者在苔藓植物分类与分布、植物化学等方面也取得一系列高质量的成果。中国科学院是全球发表苔藓植物研究文献数量最多的机构,同样表明我国学者在该领域产生了诸多成果并具有很强的实力。此外,全球苔藓植物研究方面在一定程度上呈现出多机构间激烈竞争的局面。全球发表苔藓植物研究文献最多的期刊依次为美国创办的《The Bryologist》、英国的《Journal of Bryology》和法国的《CryptogamieBryologie》,然而我国的学术刊物在此领域几乎没有国际影响力。全球对苔藓植物的研究集中在植物科学、环境科学与生态、生物化学与分子生物学等学科领域,表明在苔藓植物的分类与分布、生理生态、分子进化与系统发育以及环境监测与修复等方面研究较多。此研究结果可为掌握国内外苔藓植物研究的现状与趋势等提供基础信息,并对后续研究具有潜在的指导意义。

To understand the status of bryophytes research in the world,this paper performed a bibliometric analysis of published bryophyte research for theperiod of 1965-2017,based on database of Web of Science.The number of published papers,countries,authors,institutions,journals and subjects in bryophyte research were quantitatively analyzedinthispaper.The results showed that there were 24,784 literatures on bryophyte research in the world from 1965 to 2017.These were a general upward trend in related research.After a relatively slow start-up phase from 1965 to1989,manyresearch findings were published during the period of 1990-2017.It is expected that manyfindings will still be published in related fields in the future.The countries that published the most literatures in the world were the United States,Germany and the England.However,China ranked fifth globally,indicating that China has a high international influence in the field of bryophyte research.The scholars from Japan,Poland and Germany have published more literatures on chemical analysis,taxonomy and molecular systems in bryophytes and some scholars in China had also published a series of high-quality findings in the classification and distribution of bryophytes and phytochemistry.The Chinese Academy of Sciences isthe institution that published the most literatures on bryophyte research in the world.This result also shows that Chinese scholars have produced many achievements and have strong strength in this field.In addition,the bryophyte research has,to a certain degree,presented a fierce competition among differentinstitutions in the world.The world's most published journals of bryophytes research literature are The Bryologist(United States),Journal of Bryology(England)and CryptogamieBryologie(France).But China academic journals have little international influence in this field.The research on bryophytes in the world has focused on subjects such as plant science,environmental science and ecology,biochemistry and molecular biology.It shows that many bryophytes studiesfocus on classification and distribution,physiological ecology,molecular evolution and phylogenyas well as environmental monitoring and repair,etc.This study can provide basic information forunderstanding the status and trends of bryophyte research and may serve as a potential guide for future research.
