Abstract:

Highly reactive nitrogen loss caused by excessive nitrogen application in vegetable system has been widely concerned by the global scientific community. In order to understand the hotspots and development trends in the global research on reactive nitrogen loss in vegetable system, this study used VOSviewer visualization analysis software to conduct quantitative research and visualization analysis of 444 SCI papers published in the Web of Science core database on reactive nitrogen loss in vegetable system since the beginning of the 21st century. The results show that the research on the loss of reactive nitrogen in vegetables has gained more and more attention in the world. China and the United States are the two countries with the largest number of publications and the highest recognition of the papers. The Chinese Academy of Sciences is an important research institution in this field, and its number of published papers, local citation frequency and total citation frequency rank the first. Science of the Total Environment and Agriculture Ecosystems & Environment are the two journals with the largest number of papers published in this field. From the relationship between authors and cooperation, authors cooperate closely with those from the same cluster, and authors cooperate less with those from different clusters. The analysis of keywords co-linear hotspot evolution shows that the research hotspots in this field change from exploring nitrogen leaching and N2O emission in vegetable system at field scale to studying the influence of soil nitrogen cycle on reactive nitrogen loss in vegetable field at micro-scale by microbial indicators, estimating regional N2O by model simulation and integration analysis at macro-scale, evaluating the effect of different emission reduction measures on reactive nitrogen emission reduction, and the influence of N2O emission on greenhouse effect and soil organic carbon sequestration in vegetable field. N2O emission from vegetable fields has attracted most attention in the research on reactive nitrogen loss in vegetable system, and it is likely to be the hotspot and trend in the future.

Key words: vegetables, reactive nitrogen loss, bibliometric analysis, research hotspots
