基于Citespace的草原生态研究知识图谱分析

Analysis of Knowledge Map Based on Citespace Grassland Ecological Research

草原生态近年来受到国内外持续关注,相关领域的研究成果不断拓展。基于Web of Science核心合集数据库中检索的1995~2021年间有关草原生态的3253篇文献作为数据来源,运用Citespace软件从发文量、国家、期刊、作者、机构、关键词等角度进行分析。结果表明:共有153个国家在该领域展开了相关研究工作,其中中美两国研究较为广泛,发文量仍处于不断上升趋势,但仍未形成稳定核心作者群,《Ecology》为发表文献量最高期刊,作者与机构之间均形成了一定程度的合作,但机构间差距较大。

Grassland ecology has received continuous attention at home and abroad in recent years,and the research results in related fields have been continuously expanded.Based on 3253 literatures on grassland ecology from 1995 to 2021 retrieved from the Web of Science core collection database,this paper uses Citespace software to analyze the number of publications,countries,journals,authors,institutions and keywords.The results show that a total of 153 countries have carried out relevant research work in this field.Among them,China and the United States have carried out extensive research.The number of publications is still on the rise,but a stable core author group has not yet been formed.‘Ecology’is the journal with the highest number of publications.There has been a certain degree of cooperation between authors and institutions,but there is a large gap between institutions.
