摘　　要：甲烷在土壤生态系统中扮演着不可缺少的重要角色,甲烷排放是物质循环和能量流动的关键过程。本文旨在为未来与甲烷排放相关的研究提供有关该领域的现有研究情况和热点信息。我们使用了1979年到2022年间CNKI数据库中以“甲烷排放”为标题的相关文献作为研究基础,对发文量、研究机构、学术期刊等方面进行了数据整理,并运用Ucinet和NetDraw进行可视化分析和热点预测。研究结果表明,全国范围内,学术界在甲烷排放领域的文献发表数量逐渐增加。目前,学术界主要关注减排、稻田、土壤和排放量等研究方向。随着国内科研工作的进一步深入探讨,甲烷排放领域的研究已取得了快速发展和高质量成果。Methane is an indispensable component of soil ecosystems,playing a vital role in the material cycle and energy flow within these systems.This paper aims to provide an overview of the current research status and key areas of interest in methane emissions.It is based on relevant literature with the title“methane emission”in the CNKI database,covering the period from 1979 to 2022.The data has been organized with respect to the number of publications,institutions,journals,and other criteria.Visual analysis and hotspot prediction were conducted using Ucinet and NetDraw.The results of this study indicate a nationwide increase in the number of publications in this field.Current research predominantly focuses on emission reduction,paddy fields,soils,and emissions.With the further exploration of domestic scientific research,the research in the field of methane emission has achieved rapid development and high-quality results.
