利用文献计量软件CiteSpace对CNKI(1992～2021年)和WOS数据库(1995～2021年)草地土壤领域的文献资料做可视化分析和系统梳理。结果表明，在CNKI数据库中，《草业科学》《草业学报》《生态学报》《应用生态学报》刊载草原土壤研究成果较多;高中心性的龙瑞军、张法伟是承接作者;中国科学院大学为数据库发文量排名第一的机构;依据发文量特征将我国草原土壤研究历程划分为起步(1992～2002年)、平稳发展(2003～2012年)和波动发展(2013～2021 年)三阶段，并讨论了早期萌芽研究阶段及各阶段对应的主题。在WOS数据库中，Agriculture Ecosystems&Environment、Rangeland Ecology Management、Plant and Soil、Journal of Arid Environments上刊载草原土壤研究成果较多;高中心性的白永飞、韩兴国是前沿作者;中国科学院为数据库发文量排名第一的机构;中国发文量大，但中心性不及美国、德国等国家。最后综合分析草原土壤研究热点和前沿，指出全球气候变化背景下土壤碳氮收支问题是未来草原土壤研究主要方向。
Research Situation Analysis of Grassland Soil over the Past Three Decades Based on CiteSpace
In this study,the bibliometric software CiteSpace was used to visually analyze and systemati-cally organize literature data in the field of grassland soil from CNKI(1992-2021)and WOS database(1995-2021).The findings revealed that in CNKI database,Pratacultural Science,Acta Prataculturae Sinica,Acta Ecologica Sinica,and Chinese Journal of Applied Ecology published more grassland soil research results.Long Ruijun and Zhang Fawei of high centrality are the connecting authors.The University of Chinese Academy of Sciences ranked first in the number of documents published in the database.Accord-ing to the characteristics of the number of publications,the research progress of grassland soil in China was divided into three stages:the initiation phase(1992-2002),the stable development phase(2003-2012),and fluctuating development phase(2013-2021),and the early germination research stage and the corre-sponding themes of each stage were discussed.In the WOS database,there were many grassland soil research results published in journal of Agriculture Ecosystems&Environment,Rangeland Ecology Man-agement,Plant and Soil,Journal of Arid Environments.Bai Yongfei and Han Xingguo of high centrality are the frontier authors.The Chinese Academy of Sciences ranked first in the number of database publica-tions.China had a large number of papers,but centrality was less than that of The United States of America and Germany.Finally,the hot spots and frontiers of grassland soil research were analyzed comprehen-sively,and it was pointed out that soil carbon and nitrogen budget under the background of global climate change was the main research direction in the future.
