摘　　要：农林复合系统是一种高效的农林业发展模式,对农林业的可持续发展有着很大的意义,其中氮在该系统的生产中尤为重要。目前,对于农林复合系统中氮的研究缺乏系统的总结和归纳,需要明确该领域研究变化和趋势,为农林复合系统中有关氮的研究给予参考方向。以Web of Science核心数据库中2012—2021年发表的607篇以“农林复合系统”和“氮”为主题的文献为基础,利用CiteSpace软件对发文机构、合作作者、研究热点等进行可视化分析,以此确定农林复合系统中有关氮的研究现状和热点。结果表明,该领域发文数量呈现逐年上升的趋势;中国科学院、法国农业发展研究中心、法国蒙彼利埃大学、中国科学院大学等机构在该领域贡献较为突出,且国内和国外机构合作交流较少;研究作者呈现“整体分散,部分集中”的特点;研究热点主要包括不同的土壤管理系统下,土壤养分氮含量研究、土壤中有关氮含量的动态变化和气候变化下,森林中土壤固氮及碳固存、农林复合系统或农林业土壤中氮素与土壤有机质、植被生长的影响研究。氮对农林复合系统生产十分重要,今后学者仍需加强该领域的研究深度。Agroforestry system is an efficient agricultural and forestry development mode,which has great significance for the sustainable development of agriculture and forestry,in which nitrogen is particularly important in the production of this system.At present,the research on nitrogen in agroforestry system lacks systematic summary and induction,so it is necessary to clarify the research changes and trends in this field,so as to provide a reference direction for the research on nitrogen in agroforestry system.Based on 607 papers on‘agroforestry systems’and‘nitrogen’published in the Core database of Web of Science from 2012 to 2021,visual analysis was conducted on the publishing institutions,co-authors and research hotspots using CiteSpace software.The research status and hotspot of nitrogen in agroforestry system were determined.The results showed that the number of articles published in this field was increasing year by year.Chinese Academy of Sciences,French Research Center for Agricultural Development,University of Montpellier,University of Chinese Academy of Sciences and other institutions had made outstanding contributions in this field,and there was little cooperation and exchange between domestic and foreign institutions.The authors presented the characteristics of‘overall dispersion and partial concentration’.The research hotspot mainly included the study of soil nutrient and nitrogen content under different soil management systems,the dynamic change of soil nitrogen content,soil nitrogen fixation and carbon sequestration in forest under climate change,the influence of nitrogen and soil organic matter in agroforestry system or agroforestry soil,and vegetation growth.Nitrogen is very important for agroforestry system production,and further research in this field is needed.
