【摘要】 土壤微生物群落是生态系统的重要组成部分,在调节植物生长、促进土壤结构的形成及维持生态系统功能和稳定性等方面有着不可替代的作用。本研究运用CiteSpace文献可视化软件,对1990～2020年Web of Science核心数据库收录的6 909篇关于土壤微生物群落的文献进行数据挖掘,研究结果表明,关于土壤微生物群落研究的发文量呈指数型上升;中国和美国的发文量较多,中美之间多有合作交流;中国科学院虽然首发年限较晚,但在土壤微生物群落研究方面占有重要地位。深度挖掘土壤微生物群落研究方面的高被引文献,结合文献交叉引用分析,推测未来研究方向包括动态微生物群落、温带山地森林土壤、土壤生态系统特征和多种不可培养细菌群等;进一步利用关键词共现网络和突发性检测分析发现当前的研究热点集中于"功能多样性(functional diversity)"、"凋落物分解(litter decomposition)"和"微生物多样性(microbial diversity)"等方向。该研究结果可为土壤微生物群落研究的发展、布局以及技术的创新提供思考与借鉴。更多还原

【Abstract】 Soil microbial community is an important part of ecosystem, which plays an irreplaceable role in regulating plant growth, promoting the formation of soil structure and maintaining the function and stability of ecosystem. In this study, using CiteSpace document visualization software, data mining was conducted on 6909 articles about soil microbial community collected from the Web of Science core database from 1990 to2020. The results showed a steady increase in the number of publications in the soil microbial community area, a higher number of publications in China and the United States, and a greater number of cooperative communications between China and the United States, and a higher number of publications in the field of soil microbial community in the Chinese Academy of Sciences(CAS). Despite its late launch, CAS occupied a very important position. Based on deep excavation of highly cited literature in this field and the cross-citation analysis, it was speculated that the future research directions include dynamic microbial community, soil, soil ecosystem characteristics and many kinds of unculturable bacteria. Finally, using co-occurrence network and emergent detection, it was found that current research focuses on "functional diversity", "litter decomposition" and "microbial diversity". This study will be helpful to the development, layout and innovation of soil microbial community research.更多还原
