摘要:

蔬菜系统由于过量氮肥施用导致的高活性氮损失受到当前全球科学界的广泛关注。为了解全球蔬菜系统活性氮损失的热点和发展趋势,本研究借助VOSviewer可视化分析软件对21世纪以来发表在Web of Science核心数据库中有关蔬菜系统活性氮损失的444篇SCI论文进行计量研究和可视化分析。结果表明:蔬菜活性氮损失领域的研究在全球的受重视程度越来越高。中国和美国是发文量最多和论文受认可度最高的2个国家;中国科学院是该领域重要的研究机构,其发文量、本地被引频次和总被引频次都位居首位。Science of the Total EnvironmentAgriculture Ecosystems & Environment是该领域刊载论文量最多的2种期刊。从作者及合作关系来看,同聚类间作者合作紧密,不同聚类间作者合作较少。对关键词共线热点演变分析得知:该领域的研究热点由田块尺度上探究蔬菜系统氮淋洗和N2O排放转向微观尺度上通过微生物指标研究菜地土壤氮循环对活性氮损失的影响、宏观尺度上利用模型模拟和整合分析对区域N2O的估算、不同减排措施对活性氮减排效果的评估、菜地的N2O排放对温室效应和土壤有机碳固存的影响。菜地N2O排放作为蔬菜系统活性氮损失领域的研究发展过程中关注度最高的研究主题,未来也极有可能是该领域发展的热点和趋势。

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
