环境磁学领域研究现状与趋势——基于VOSviewer的文献计量和可视化分析

Status and trend of the research in environmental magnetism field-bibliometric and visualization analysis based on VOSviewer

为了解环境磁学的研究现状、热点及趋势,以中国学术期刊网络出版总库为数据来源,将时间区间设定为2000-2020年,提取环境磁学领域发表的相关学术文献,基于文献计量学分析方法,借助数据挖掘可视化软件VOSviewer对作者、学术期刊类型以及文献关键词进行聚类分析,结果表明:自2013年以来,环境磁学领域发表的论文数量急剧攀升;我国该领域的主要研究者有夏敦胜、刘青松、贾佳等;中文文献关键词频次居前列的是“环境磁学”“磁化率”“磁性矿物”“重金属”,英文文献关键词频次居前列的是“magnetic susceptibility”“heavy metals”“magnetic pro-perties”;刊载环境磁学科研成果数量居前列的SCI期刊是Science of the Total Environment,Atmospheric Environment,Environment Pollution,Journal of Geophysics and Engineering等。

In order to understand the status,highlights and the trend of research on environmental magnetism,in this paper the general database of Chinese academic journals on-line published was taken as the data source,the duration was set to be 2000-2020,the relevant academic documents published in the field of environmental magnetism was extracted,the clustering analysis on the authors,category of academic journals and keywords was undertaken based on bibliometric analysis method and by means of the software for visualized data mining.The results indicate that since 2013 the number of papers published in the field of environmental magnetism has increased dramatically.The names of key Chinese scholars appeared in this field were Xia Dunsheng,Liu Qingsong,Jia Jia and so on.The keywords with top frequency ranking presented in Chinese documents were"environmental magnetism","susceptibi-lity","magnetic minerals"and"heavy metals".The keywords with top frequency ranking in English document were"magnetic susceptibility","heavy metals",and"magnetic properties".The SCI journals that published the top number of scientific research achievements in environmental magnetism field were Science of the Total Environment,Atmospheric Environment,Environment Pollution,Journal of Geophysics and Engineering,etc.
