Based on the databases of China National Knowledge Infrastructure (CNKI) and Web of Science, statistical analysis was conducted on journal papers regarding ammonia nitrogen treatment in weathered crust elution-deposited rare earth tailings from November 2009 to November 2024. CiteSpace was employed to perform visual analysis of the temporal distribution, authors, collaboration networks, research hotspots and research frontiers in this field. The research progress was systematically summarized in the form of knowledge maps, so as to provide research directions and theoretical support for soil ecological restoration and residual ammonia nitrogen pollution control in closed mining areas of weathered crust elution-deposited rare earth ores. The results show that the number of relevant publications exhibited an overall upward trend during the 15-year period. Most high-yield authors were from universities, with research dominated by team collaboration, and the vast majority of authors and institutions were from China. Although different studies had varied focuses, they all centered on ammonia nitrogen treatment and ecological governance of weathered crust elution-deposited rare earth tailings. Soil pollution prevention and ecological restoration have become research frontiers. Future research should strike a balance among treatment efficiency, remediation cost and green sustainable development.

以中国知网（CNKI）和Web of Science数据库为数据源，对2009年11月至2024年11月期间发表的关于风化壳淋积型稀土尾矿中氨氮处理研究的期刊论文进行统计，利用CiteSpace软件对其时间分布状况、发文作者、合作网络、研究重点以及研究前沿进行可视化分析，以图谱化形式系统概括该领域研究情况，为风化壳淋积型稀土矿闭矿区土壤生态修复与残留氨氮污染治理提供研究方向和理论支撑。结果表明，15年间相关文献数量呈上升趋势；高产作者多来自高校，以团队合作为主；大多数作者和机构均来自中国；不同研究虽侧重点各异，但均围绕风化壳淋积型稀土尾矿中氨氮处理以及生态治理展开。土壤污染防护和生态修复已成为研究前沿，未来研究需在处理效率、治理成本与绿色可持续发展之间寻求平衡。
