摘　　要：为剖析2000—2022年国内外湖泊氮沉积研究的发展历程、热点与趋势,利用文献计量学软件CiteSpace,主要从合作网络、文献被引和关键词三个方面,对Web of Science(WOS)和中国知网(CNKI)数据库中的相关文献进行了可视化计量分析.研究结果显示:(1)23年来,湖泊氮沉积领域研究成果高度集中于中国和美国;(2)领域内的研究热点依次为富营养化、流域视角下的氮形态及其转化、湖泊综合环境效应;(3)未来研究需重点关注气候变化与人类活动双重作用下流域氮的动态变化及其驱动因素,以及湖泊氮素数据库的完善和复合污染评价.To analyze the research development stage,hotspots,and future trend of lake nitrogen deposition worldwide from 2000 to 2022,the bibliometrics software CiteSpace was applied to visualize the related literatures in the Web of Science(WOS)and China National Knowledge Infrastructure(CNKI),focusing on collaborative networks,literature citations,and keywords.Results show that:(1)In the past 23 years,the research achievements in lake nitrogen deposition have been concentrated in China and America.(2)The hotspots include eutrophication,nitrogen morphology and its transformation from watershed perspective,and lake comprehensive environmental effects in turn.(3)Future research needs to focus on the dynamic change of nitrogen and its drivering factors in watersheds under the dual effects of climate change and human activities,as well as the improvement of lake nitrogen databases and the assessment of compound pollution.
