Research progress of soil bacteria based on bibliometrics

doi:10.13733/j.jcam.issn.20955553.2021.12.33

Abstract

Abstract: Soil bacteria are the most widely distributed and largest microbial group, which plays an irreplaceable role in the soil environment. To better explore the hotspot of soil bacteria, 34 918 papers were collected from the Web of Science from 2010 to 2020 and were visualized by bibliometric analysis. The results show the following. The amount of research on soil bacteria showed a trend of gradual increase and did not reach saturation state, which had a broad development prospect. China has published the highest number of papers in the soil bacteria field, accounting for 27.09% of the global total, with 9 458 papers. Among the top 10 scientific research institutions and scholars, China occupies 6th and 4th places, respectively. In recent years, the focus and hotspot of research is the production and maintenance mechanism of soil bacterial diversity and the function of soil bacteria, including the spatial distribution of bacteria and the response to the environment, community assembly, biogeochemical cycling, microbial remediation, and the health of plants and soil. Although soil bacteria research has strong application prospects, it still faces significant challenges. Therefore, we must break through the existing technical means to link the characteristics of soil bacteria to ecosystem functions and promote its development.

摘要： 利用文献计量法，结合CiteSpace和VOSviewer 可视化分析技术，对2010—2020年Web of Science核心合集数据库中土壤细菌相关文献进行可视化分析，为土壤细菌领域研究者跟踪研究前言、把握研究方向提供理论参考。结果表明：土壤细菌领域发文量呈现逐步上升趋势，未达饱和状态，具有广阔的发展前景；中国是土壤细菌研究领域发文数量最多的国家，达9 458篇，占全球总发文量的27.09%；发文量排名前10位的科研机构和学者发文量中国分别占据6位和4位；土壤细菌研究方法、土壤细菌多样性的产生和维持机制（包括土壤细菌群落空间分布及环境响应、群落构建过程）以及土壤细菌的功能特征（包括生物地球化学循环、微生物修复、植物和土壤健康）是近年来该领域内研究的重点和热点。综合来看，土壤细菌研究具有较强的应用前景，但面临的挑战仍很大，需要突破现有技术手段对其注释，将土壤细菌特性和生态系统功能联系起来，推动其向前发展。
