摘　　要：为了深入了解土壤氮素矿化的研究现状和发展趋势,应用CiteSpace信息可视化分析软件,对Web of Science(WOS)数据库中1990—2020年土壤氮素矿化领域的1804篇文献进行了基础知识框架、研究热点、发展趋势的可视化分析,对土壤氮素矿化研究进展和演变趋势进行了图谱解读和追踪分析。结果表明:土壤氮素矿化研究正处于不断发展阶段;该领域研究具有很强的学科交叉特点,主要涉及环境科学与生态学、生态学、环境科学和农业等学科;其重要研究主题是土壤氮素转化机理及其动力学过程;近期研究前沿主要集中在探究不同土地利用类型或农业管理措施对微生物特性的影响、微生物又影响土壤中氮素迁移转化过程方面;我国该领域研究发展迅速,但还面临在国际上影响力较低等问题。In order to deeply understand the research status and development trend of soil nitrogen mineralization,the CiteSpace information visualization analysis software was used to conduct a visual analysis on the basic knowledge framework,research hotspots and development trends,from 1804 documents in the field of soil nitrogen mineralization based on the web of science(WOS)database from 1990 to 2020.The results showed that the research on soil nitrogen mineralization is in a stage of continuous development showing a strong interdisciplinary trend in the fields of environmental science,ecology and agriculture.The important research topics in this field were the mechanisms and dynamics of soil nitrogen transformation.Recently,the research was mainly focused on the effects of different land use types or agricultural management measures on microbial characteristics,which in turn affecting the process of soil nitrogen transfer and transformation.The contribution from Chinese researches were increasing rapidly,but the impacts is still low in the international arena.
