湿地松研究文献计量分析——基于CNKI和WOS数据库

Bibliometric analysis of Pinus elliottii research literature——based on CNKI and WOS database

为了解湿地松的研究现状与研究热点,以中国知网(CNKI)数据库和Web of Science(WOS)数据库中2000-2020年湿地松文献为研究对象,借助CiteSpace软件对作者、关键词、文献共被引等方面进行分析。结果表明:CNKI数据库的发文量滞后于WOS数据库,国内研究者有偏向于投稿国外期刊的趋势,近几年WOS数据库中的发文量呈显著增长趋势。湿地松研究主要集中在组织培养、育种、林产品、碳动态、养分、光合作用等方面,并已形成稳定的核心作者群。与国外研究相比,国内研究更着重关注湿地松产脂性状、木材利用等经济效益,在生态环境方面研究相对薄弱。从关键词时区图可以看出,自2013年以后,国内湿地松研究的高频关键词较少,新的研究热点尚未形成。

In order to understand the research status and hotspots of Pinus elliottii,the literature of P.elliottii from 2000 to 2020 in CNKI database and Web of Science(WOS)database were studied and the authors,keywords and co citation of literature were analyzed by CiteSpace software.The results show that the number of papers published in CNKI database lags behind that of WOS database,and domestic researchers prefer to contribute to foreign journals.In recent years,the number of papers published in WOS database shows a significant growth trend.A stable core group of authors has been formed in the field of P.elliottii research.The research hotspots mainly focus on tissue culture,breeding,forest products,carbon dynamics,nutrients,photosynthesis and so on.Compared with foreign studies,domestic researches pay more attention to the economic benefits of P.elliottii,such as rosin production characteristics and wood utilization,while the research on ecological environment is relatively weak.It can be seen from the keywords timezone map that since 2013,there are few high-frequency keywords in the study of P.elliottii in China,and new research hotspots have not yet formed.
