Abstract:

In order to explore the hot spots and trends of nitrogen cycling research of the last decade, based on the CNKI database, this study used bibliometrics to summarize the literature types, source countries, research institutions, publishing journals and frequently cited literature, and then analyzed the general situation and trends of nitrogen cycling research. The results showed that: (1) from 2012 to 2021, the number of publications related to nitrogen cycling showed a steady increase year by year, and the main publication types were foreign language journals, academic dissertations and Chinese journals; (2) the main research countries were China and the United States, the research institutions were mainly universities, and the Chinese Academy of Sciences was one of the important institutions of nitrogen cycling research; (3) Science of the Total Environment from the Netherlands, Frontiers in Microbiology from Switzerland and Soil Biology & Biochemistry from the UK had the highest numbers of publications; (4) the literature cited frequently were mainly reviews, and their research direction was mainly focused on soil nitrogen cycling. In general, the related research on nitrogen cycling has a good development trend, and relevant theories have gradually enter the stage of comprehensive and in-depth systematic research, and formed the main research direction of soil nitrogen cycling in agricultural ecosystem.
