基于 2000-2023 年中国知网(CNKI)数据库和Web of Science(WOS)核心合集数据库的文献数据，利用CiteSpace软件从发文量、发文作者、发文机构、发文国家、关键词等方面系统分析了农业面源磷污染领域的研究现状和发展趋势。结果显示:中文文献发文量整体呈先上升后下降的趋势，英文文献发文量整体呈波动上升趋势;中英文发文量最多的作者分别是李怀恩和沈珍瑶;中英文发文量最多研究机构分别是武汉大学水资源与水电工程科学国家重点实验室和中国科学院;英文发文量最多的国家是中国。当前国内外研究聚焦于磷的时空分布特征和迁移转化规律、面源污染模型的评价、应用和改进、磷污染的风险评估及其治理修复等方面。未来的研究重点为开发和改进具有本地特色且高效的农业面源污染模型，并在流域尺度上进行磷污染的溯源和迁移模拟，研究磷的遗留效应，深度挖掘磷的迁移转化机理。
Research Status on Phosphorus in Agricultural Non-Point Source Pollution Based on Bibliometrics
The articles about phosphorus in agricultural non-point source pollution were retrieved from the Web of Science(WOS)core collection and the China National Knowledge Infrastructure(CNKI)with the time interval of 2000 to 2023.CiteSpace was employed to comprehensively analyze the research status and trend on phosphorus in agricultural non-point source pollution in terms of annual number of publications,authors,research institutions,countries,and keywords.The results showed that the annual number of publications in Chinese first increased and then decreased,while that in English kept rising with fluctuations.Li Huai'en and Shen Zhenyao were the authors publishing the most articles in Chinese and English,respectively.The State Key Laboratory of Water Resources and Hydropower Engineering Science,Wuhan University and the Chinese Academy of Sciences were the research institutions publishing the most articles in Chinese and English,respectively.China was the country with the largest number of papers published by WOS in this field.The available studies about phosphorus in agricultural non-point source pollution focused on the spatiotemporal distribution characteristics,the migration and transformation patterns,the evaluation,application,and improvement of non-point source pollution models,and the risk assessment and remediation of phosphorus pollution.In the future,efforts should be made to develop efficient non-point source pollution models considering local characteristics,conduct tracing and migration simulation of phosphorus pollution on the watershed scale,study the legacy effect of phosphorus,and decipher the migration and transformation mechanisms of phosphorus.
