Nitrogen (N) inputs caused by human activities potentially influences the aquatic environment. However, researches on N pollution in China are mainly discussed from the microscopic point of view, i. e. field experiment. Watershed-scale diagnosis of N pollution has just started, leading to ambiguous identification of ecological problems, pollution issues and pollution potential at watershed scale. In this paper, relationships between net anthropogenic N inputs (NANI) and riverine N flux (RNF) and factors influencing these relationships at watershed scale had been investigated. This would help diagnose ecological and environmental problems at watershed scale, understand the roles of natural climate and human activities in affecting N fluxes, and ultimately provide both theoretical and practical insights into environmental management decisions.
人类活动引起的氮（N）输入可能会影响水生环境。然而，中国关于氮污染的研究主要是从微观角度进行讨论的，即实地试验。流域尺度的氮污染诊断刚刚起步，导致在流域尺度上对生态问题、污染问题和污染潜力的识别不明确。本文研究了流域尺度上人为净氮输入（NANI）与河流氮通量（RNF）之间的关系以及影响这些关系的因素。这将有助于诊断流域尺度上的生态和环境问题，了解自然气候和人类活动在影响氮通量方面的作用，并最终为环境管理决策提供理论和实践见解。
