摘要：

基于巢湖流域农业面源污染防治相关国内外文献，分析该研究领域的动态变化，包括发展过程、研究热点、动态前沿和未来可能的研究方向。以1998—2023年6月中国知网、万方数据、维普网及Web of Science核心合集收录的394篇相关文献为数据源，利用CiteSpace软件绘制巢湖流域农业面源污染研究知识图谱，分析作者、机构、来源期刊分布，从动态视角研究主题的发展过程。结果表明：（1）该研究领域的发展过程可分为4个阶段，发文量与巢湖总氮、总磷变化趋势相关，整体认知水平有待提高。（2）中文文献对该领域的研究热点主要集中在氮磷流失、畜禽养殖、空间分布和对策等方面，英文文献对该领域的研究热点集中在径流、污染物的影响、分析污染物的来源和管理措施等方面，人工湿地对面源污染的研究仍是其空白领域。（3）未来研究的突显方向包括利用“3S”等技术定量刻画污染发生的复杂时空过程，揭示农业面源污染迁移转化的过程机理，预测污染物负荷下水环境的变化；在保证粮食产量的前提下，全过程靶向施肥，精准控肥，减少氮磷流失。巢湖农业面源污染治理是一项长期持续性的工作，需要增加各部门、机构之间的联动协作建立统一的信息数据库，让更多国内外学者了解和参与巢湖治理。

Abstract:

Based on the domestic and international literature related to the management of agricultural non-point source pollution in Chaohu Lake, the dynamic changes in the field were analyzed, including its development process, research hotspots, dynamic frontiers and possible future research directions. Taking 394 relevant literatures included in CNKI, Wanfang data, Wipro database and Web of Science core ensemble published between 1998 to June 2023 as data sources, CiteSpace visualization and analysis software were employed to draw the knowledge map of Chaohu Lake’s non-point source pollution research. This allowed for an analysis of the distribution of authors, institutions and journals involved in the research as well as a study of the development from a dynamic viewpoint. The results indicated that (1) the development process could be divided into four stages and the paper issuance numbers were correlated with trends in total nitrogen and total phosphorus changes in Chaohu Lake. Furthermore it was found that there was room for improvement regarding overall knowledge levels within this field. (2) The research hotspots identified within Chinese literature mainly focused on nitrogen and phosphorus loss, livestock and poultry farming, spatial distribution and countermeasures. Conversely English literature focuses on runoff, impacts of pollutants, analyzing sources and management measures of pollutants. The research on non-point source pollution in artificial wetlands was still a blank field. (3) The prominent direction of future research was to use “3S” and other technologies to quantitatively characterize the complex spatiotemporal processes of pollution occurrence, revealing the mechanism of migration and transformation of agricultural non-point source pollution, and predicting changes in the “water environment” under pollutant load. Under the premise of stabilizing yield, the whole process involved implementing targeted fertilization, precise fertilizer control, and reducing nitrogen and phosphorus loss. The management of agricultural non-point source pollution in Chaohu Lake is a long-term and continuous endeavor that requires increased collaboration between various departments and institutions to establish a unified information database. This also requires more understanding and participation from domestic and foreign scholars in the management of Chaohu Lake.
