生态化学计量研究的核心期刊文献计量分析

Bibliometric Analysis of the Core Journals of Eco Stoichiometry

为深入了解生态化学计量研究领域的核心期刊论文发表的现状,该文采用文献计量学的研究方法,通过高级搜索方式,以2011—2020年的CNKI数据库所收录的北大核心刊物文献为主要研究对象,从年度发文量、作者发文量、高被引文献、高频关键词、主要发文期刊和主要发文机构等角度进行了分析。结果表明,共检索到相关文献468篇,从整体来看,年度发文量呈逐步增长趋势,2011—2015年为初期探索阶段,2016—2020年为快速发展阶段;发表4篇核心期刊论文的仅有1人(黄菊莹),排名前5的作者单位均位于西部地区。被引用频次前10的核心期刊论文分别发表在《生态学报》和《植物生态学报》这2种期刊上;排名前3的高频关键词分别是生态化学计量学、土壤和凋落物。土壤养分是生态化学计量领域的重要的研究对象;发文量排名前3的期刊分别是生态学报、植物生态学报、生物学杂志和应用生态学报(并列第3);发文量排名前3的机构分别是分别是中国科学院(79篇)、西北农林科技大学(54篇)和中国科学院大学(39篇)。以上结果可为生态化学计量领域的进一步研究提供参考依据。

In order to deeply understand the current situation of the publication of core journal papers in the field of eco stoichiometry,this paper adopts the research method of bibliometrics and takes the core journal literature of Peking University included in CNKI database from^(2)011 to 2020 as the main research object,and analyzes it from the perspectives of annual publication volume,author publication volume,highly cited literature,high-frequency keywords,main publication journals and main publishing institutions,The results show that a total of 468 relevant literatures have been retrieved.On the whole,the annual number of documents issued shows a gradual growth trend.The initial exploration stage is from^(2)011 to 2015,and the rapid development stage is from^(2)016 to 2020;Only one person(Huang Juying)published four core journal papers,and the top five author units are located in the western region.The core journal papers with the top 10 citation frequencies were published in the Journal of ecology and the Journal of plant ecology respectively;The top three high-frequency keywords are eco chemometrics,soil and litter.Soil nutrients are important research objects in the field of eco stoichiometry;The top three journals in the number of publications are ecology,plant ecology,biology and Applied Ecology(tied for the third);The top three institutions in terms of the number of publications are the Chinese Academy of Sciences(79),the Northwest University of agriculture and forestry science and Technology(54)and the University of the Chinese Academy of Sciences(39).The above results can provide a reference for further research in the field of eco stoichiometry.
