摘　　要：刊发文章所标引的关键词是文献检索的标志之一,既可以反映文章的主题有利于读者快速检索到需要的文献,又可以通过关键词分析得到该学科的研究热点等重要信息。本文对林业类8种期刊在2014—2018年的刊发文章关键词进行统计,以这8种期刊刊发文章所标引的关键词为研究对象,通过统计关键词标引率和词频,利用共词网络和多维尺度分析方法,分析刊发文章关键词和林业领域的研究热点之间的关系。研究表明,8种期刊关键词标引率均达100%,使用关键词获取该学科研究方面的重要信息具有可行性;采用词频分析、共词网络分析和多维尺度分析得出了能够反映该学科当前研究热点的关键词和研究热点,并验证了其中4类热点的准确性。旨在提醒作者重视关键词的使用。The keywords indexed by published articles are one of the signs of literature retrieval,which can not only reflect the theme of the article and help readers quickly retrieve the required literature,but also obtain important information such as research hotspots in the subject through keyword analysis of multiple journals.This paper makes statistics on the keywords of articles published in eight forestry journals from 2014 to 2018,and takes the keywords indexed by the articles published in these eight journals as the research object.Co-word network and multi-dimensional scaling analysis methods are used to analyze the relationship between published article keywords and research hotspots in the field of forestry.The research shows that:the indexing rate of keywords in eight journals is 100%,and it is feasible to use keywords to obtain important information in the research of this discipline.Using word frequency analysis,co-word network analysis and multi-dimensional scaling analysis,the keywords and research hotspots that can reflect the current research hotspots of the discipline are obtained,and the accuracy of four types of hotspots is verified.It is intended to remind the author to pay attention to the use of keywords.
