Abstract:

This research used China National Knowledge Network (CNKI) and Web of Science database from 2005 to 2020 as the document source, and bibliometric method was used to analyze the current status of soil microbial metagenomics research field. The results show that the studies on soil microbial metagenomics conducted by Chinese and foreign scholars using high-throughput technology increase continuously. The research objects are mainly about bacteria and fungi. The research habitats involve rhizosphere, sediment, and etc. There is close cooperation between research institutions and authors of English publications, while the cooperation between institutions and authors of Chinese publications is mainly centered on the Chinese Academy of Sciences system. In terms of publication quality, the citation rate of the literature published by American scholars is the highest, while the citation rate of literature published by Chinese scholars is relatively low. Based on the results of literature analysis, we suggest that the future high-throughput sequencing-based soil microbial metagenomics research should focus on interdisciplinary study, further strengthen cooperation among institutions and researchers, and use innovative thinking to comprehensively analyze soil microbial at different levels such as gene and function level, thus deeply exploring the ecological functions of soil microorganisms and providing services for the sustainable development of the ecosystem.
