Metagenomics methods enable the determination of the microbial community found in an environment, and the study of microbial diversity and function. These techniques accelerated the study of the soil microbiome, an important component for global nutrient cycling in diverse ecosystems, including forests and grasslands. We performed a review and bibliometric analysis based on scientific studies published between 2000 and 2019, using the online tools provided by Clarivate analysis - Web of Science Core Collection database. We set up to identify research trends revolving around soil metagenomics in forest and grassland ecosystems, particularly those related with management regimes. Our results showed a rapid growth in the number of papers and a growing interest among the scientific community. Diversity of soil microbial communities was the prime subject addressed for both ecosystems. In top papers, commercial kit extraction methods were preferred, the main NGS technique was pyrosequencing, with Illumina systems gaining traction in the last decade, and bacterial communities were the most studied. This field of research showed a higher average number of citations per paper than related research topics, such as microbiology or environment/ecology. Understanding functional diversity and the ecological and applied potential of soil microbiomes is one of the current trends in soil metagenomics studies.

元基因组学方法可以确定环境中发现的微生物群落，并研究微生物的多样性和功能。这些技术加速了土壤微生物组的研究，土壤微生物组是包括森林和草原在内的各种生态系统中全球养分循环的重要组成部分。我们使用Clarivate analysis-Web of Science Core Collection数据库提供的在线工具，根据2000年至2019年发表的科学研究进行了回顾和文献计量分析。我们着手确定围绕森林和草地生态系统中土壤宏基因组学的研究趋势，尤其是那些与管理制度有关的趋势。我们的研究结果表明，论文数量迅速增长，并且科学界的兴趣日益浓厚。土壤微生物群落的多样性是针对这两个生态系统的首要主题。在顶级论文中，商业试剂盒的提取方法是首选，NGS的主要技术是焦磷酸测序，Illumina系统在最近十年获得了关注，细菌群落的研究最多。该研究领域显示出每篇论文的平均被引用次数比相关研究主题（例如微生物学或环境/生态学）高。了解土壤微生物组的功能多样性以及生态和应用潜力是土壤宏基因组学研究的当前趋势之一。和细菌群落是研究最多的。该研究领域显示出每篇论文的平均被引用次数比相关研究主题（例如微生物学或环境/生态学）高。了解土壤微生物组的功能多样性以及生态和应用潜力是土壤宏基因组学研究的当前趋势之一。和细菌群落是研究最多的。该研究领域显示出每篇论文的平均被引用次数比相关研究主题（例如微生物学或环境/生态学）高。了解土壤微生物组的功能多样性以及生态和应用潜力是土壤宏基因组学研究的当前趋势之一。
