流域面源污染是水环境质量恶化的重要原因，已成为全球环境管理工作者关注的焦点。为深入了解国内外流域面源污染防治的研究趋势和重点，基于文献计量学，对Web of ScienceTM核心合集数据库中流域面源污染管理文献进行定量分析。结果表明:2001-2021年间流域面源污染防治领域发文量共 1 327篇且发文量逐年递增，北京师范大学(Beijing Normal University)是发文量最大的研究机构(95篇)，其中SHEN Zhenyao教授发文量最多(44)篇。该领域研究热点为利用模型对地表径流中的氮、磷污染负荷进行相关研究，并采用流域面源污染管理措施以控制面源污染;通过加大投资力度、单元主体转换为多元主体、推广技术支撑、实行-区域-方案和强化监督管理，增强人民群众的环保意识，可以有效加强我国流域面源污染的防治与管理。
Analysis on research progress of watershed non-point source pollution prevention and management model——Based on bibliometrics method
Watershed non-point source pollution is an important cause of water environmental quality deterioration,and has become the focus of global environmental management workers.To understand the research trend and focus of the prevention and control of non-point source pollution in river basins at home and abroad,based on bibliometrics,the literature on watershed non-point source pollution management in Web of ScienceTM core collection database was quantitatively analyzed.The results showed that from 2001 to 2021,a total of 1327 articles were published in the field of non-point source pollution prevention and control in the watershed,and the number of articles has been increasing year by year.Beijing Normal Univ is the research institution with the largest number of articles(95 articles),among which Professor SHEN Zhenyao has the highest number of articles(44 articles).The research focus in this field is to study the nitrogen and phosphorus pollution loads in surface runoff by using models,and adopt watershed non-point source pollution management measures to control non-point source pollution.The prevention and management of non-point source pollution in river basins can be effectively strengthened by increasing investment,transforming the unit subject into multiple subject,popularizing technical support,implementing one region one plan and strengthening supervision and management,and enhancing people's awareness of environmental protection.
