摘 要：为了解近5年土壤微生物研究现状和热点，以Web of Science核心集合为数据源，利用CiteSpace软件、VOSviewer软件，分析2015—2020年发表的与土壤微生物有关的研究性论文的数量、学科、刊物、国家/地区与机构、研究热点。结果表明：（1）土壤微生物相关研究越来越受重视，发文数量增加迅速;（2）环境科学与生态学、农学和环境科学等学科对土壤微生物的相关研究最多，土壤微生物相关研究在Soil Biology & Biochemistry、Applied Soil Ecology和Science of The Total Environment等期刊上具有较高的发文量和引用次数;（3）中国、美国、德国、澳大利亚、英格兰等国家在该领域发文最多且合作密切;中国科学院、中国科学院大学、俄克拉荷马大学、清华大学、美国劳伦斯伯克利国家实验室等机构发文较多且合作密切;周集中和Kuzyakov Yakov是土壤微生物领域发文数量和被引用次数最多的作者;（4）该领域研究热点从前期土壤微生物量及组成与功能研究，到土壤微生物群落的结构和功能，再到土壤微生物多样性、土壤微生物结构与功能，以及在土壤元素生物地球化学循环，土壤微生物与环境之间关系等方面。

Abstract： In order to understand the current research status and hot spots of soil microorganisms in the past five years， the number， disciplines， journals， countries/regions， institutions and research hotspots of research papers related to soil microorganisms published from 2015 to 2020 were analyzed with the core collection of Web of Science as the data source and the software CiteSpace and VOSviewer as the software. The results showed that ：（1） More and more attention was paid to soil microbial research， and the number of articles published increased rapidly;（2） Subjects such as Environmental Science and Ecology， Agriculture and Environmental Science have the most studies on soil microorganisms. Soil microbial researches have a high number of publications and citations in journals such as Soil Biology & Biochemistry， Applied Soil Ecology and Science of The Total Environment.（3） China， the United States， Germany， Australia， England and other countries have the most publications and close cooperation in this field; The Chinese academy of sciences， the university of Chinese academy of sciences， the university of Oklahoma， Tsinghua university， Lawrence Berkeley national laboratory and other institutions have published many articles and cooperated closely. Zhou Jizhong and Kuzyakov Yakov are the authors with the most published and cited articles in the field of soil microbiology.（4） Research focuses in this field range from the preliminary study of soil microbial biomass and composition and function， to the structure and function of soil microbial community， to soil microbial diversity， soil microbial structure and function， as well as the biogeochemical cycle of soil elements and the relationship between soil microorganisms and the environment.

土壤微生物数量巨大，种类繁多，是连接不同圈层物质与能量交换的重要纽带，同时也是推动土壤物质转化、能量流动和营养元素生物地球化学循环的动力，被称为地球关键元素生物地球化学循环过程的引擎[1-4]。土壤微生物对环境变化敏感，可反映生态系统功能变化和土壤质量的敏感指标[5，6]。……
