摘要：城市化进度加快，工农业生产活动强度提升，城市河流的氮污染问题越来越突出，已经成为限制区域水环境质量与生态健康的关键因素。现在国内不少城市的河流，总氮、氨氮浓度一直超出标准，让水体富营养化、生态系统退化这些问题出现，而污染来源复杂、没法明确各来源的贡献比例，防控措施不成体系，是治理工作里的主要难题。本文选取典型城市河流作为研究对象，结合开展水化学分析、同位素示踪、多元统计模型等工作，全面梳理不同形态氮污染的空间分布特点，明确各主要污染来源的贡献占比。

Abstract：With the accelerated pace of urbanization and the increased intensity of industrial and agricultural production activities, the issue of nitrogen pollution in urban rivers has become increasingly prominent, posing a key constraint on regional water environmental quality and ecological health. Currently, many rivers in domestic cities exhibit total nitrogen and ammonia nitrogen concentrations that consistently exceed standards, leading to issues such as eutrophication and ecosystem degradation. The complexity of pollution sources, the inability to ascertain the contribution proportion of each source, and the lack of a systematic approach to prevention and control measures constitute major challenges in governance efforts. This paper selects typical urban rivers as the research subjects and combines hydrochemical analysis, isotopic tracing, and multivariate statistical modeling to comprehensively examine the spatial distribution characteristics of different forms of nitrogen pollution and clarify the contribution proportion of each major pollution source.
Keywords : urban river；nitrogen pollution；source analysis；prevention and control technology
