基于CiteSpace的2012~2021年国内外草地施肥研究文献计量分析

Research of Domestic and International Grassland Fertilization in the 2012~2021 Based on CiteSpace Bibliometric Analysis

施肥在草地生态功能恢复和草地生产力维持方面具有重要作用。为全面了解2012~2021年国内外草地施肥研究的现状、热点及前沿动态,基于文献计量学分析方法,以CiteSpace可视化软件为主要研究工具,对Web of Science(WOS)数据库和中国知网(CNKI)数据库2012~2021年收录的草地施肥研究成果进行了分析。结果表明,2012~2021年该领域的研究成果在国外期刊的发文量逐年上升,且刊载量大的期刊多为生态学领域的顶级期刊,而国内期刊的发文量在56~84篇之间,始终处于动态平衡;在国家发文量的排序中,中国排名第1位,美国和德国分别位列第2位和第3位。国内不同地区的作者或研究机构之间联系不够紧密,而团队内部人员之间合作紧密。在未来的草地施肥研究中,研究热点主要关注氮素添加对草地植物和土壤的影响,以高寒地区为研究区域,对草地群落结构和化学计量特征的研究仍具有一定的研究价值。

Fertilization plays a crucial role in the restoration of grassland ecological functions and maintenance of grassland productivity.To comprehensively assess the research progress,and identify hotspots and frontier developments in domestic and international grassland fertilization research in the 2012~2021,this study employed bibliometric analysis methods.Specifically,CiteSpace visualization software was used as the main research tool to analyze the research outputs on grassland fertilization in the Web of Science(WOS)database and the China Knowledge Network Infrastructure(CNKI)database from 2012 to 2021.The results showed that the research achievements in this field differed between domestic and foreign journals.The number of papers published in foreign journals showed an upward trend each year,with many of the publications appearing in leading ecology journals,while the number of domestic publications was 56~84,and remained relatively stable.China ranked first in the number of publications,followed by the United States and Germany.While authors and research institutions within China showed weak connectivity,there was intensive collaboration within the research team.Future research on grassland fertilization is expected to primarily focus on the impact of nitrogen addition on grassland plant and soil,with the alpine region being a major research area.There is still considerable value in studying grassland community structure and stoichiometric characteristics in these regions.
