基于文献计量的近30年国内外种植甘薯土壤研究进展分析

Analysis of research on sweetpotato planting soil at home and abroad in the past 30 years based on bibliometrics

为了解国内外种植甘薯土壤的研究进展,借助VOSviewer、CiteSpace可视化分析软件对CNKI数据库和Web of Science中核心合集数据库中,1992-2021年国内外发表的种植甘薯土壤研究论文的发文量、被引频次、机构、关键词和研究热点等信息进行系统分析。结果表明,国内外在种植甘薯土壤研究领域的发文量均呈现出波动上升趋势,美国发文总量最多,其次是中国。美国农业部的发文量、被引总频次均位居第一,且同国内外各机构合作密切。涉农高校是国内研究种植甘薯土壤的中坚力量,但各机构间的合作较少。关键词聚类分析和突变检测发现,国内侧重于栽培技术的研究,国际上更倾向于甘薯土壤环境安全的研究。本文为了解种植甘薯土壤研究的现状和进展提供一定的参考价值。

In order to understand the research progress of sweetpotato planting soil at home and abroad,the information published at home and abroad from 1992 to 2021 in the CNKI database and the core collection database of Web of Science was systematically analyzed with the help of VOSviewer and CiteSpace visual analysis software.The information included the number of published papers,citation frequency,institutions,keywords and research hotspots.The results showed that the number of publications in the field of sweetpotato planting soil at home and abroad showed a fluctuating upward trend.The United States had the largest number of articles,followed by China.The United States Department of Agriculture(USDA)ranked first in the number of publications and the total frequency of citations,and cooperated closely with various institutions at home and abroad.Agriculture-related universities were the backbone of domestic research on sweetpotato planting soil,but there was less cooperation among institutions.Keyword cluster analysis and mutation detection showed that the domestic research focused on the cultivation technology,and the international research on sweetpotato soil environmental safety was more inclined.This paper provides a certain reference value for understanding the research status and progress in the field of sweetpotato planting soil.
