[目的]研究五大连池地区30个天然露头泉氮、磷污染特征，为五大连池天然矿泉资源的可持续开发利用和保护提供理论依据。[方法]选择不同环境区域有代表性的30个天然露头泉，分别于枯水期、平水期、丰水期进行样品采集，测定样品中氮、磷等污染物的含量，分析五大连池天然露头泉氮、磷污染特征。[结果]五大连池地区30个天然露头泉总体受到严重的氮素污染，总氮和硝态氮是主要的氮素污染形式，总磷和氨氮含量较低。[结论]天然露头泉污染主要是由农业面源污染造成的。

Objective] The research aimed to study the characteristics of nitrogen and phosphorus pol ution of 30 natural outcrop springs in Wudalianchi, which provides a theoretical basis for the sustainable development and utilization and protection of Wudalianchi natural mineral resources. [Method] Choosing the 30 natural outcrop spring representatives in different regions, samples were col ected in low water peri-od, normal water period, wet period respectively, and the content of nitrogen, phos-phorus and other contaminants in the samples were determined. Besides, the pol u-tion characteristics of nitrogen and phosphorus in Wudalianchi natural outcrop spring were analyzed. [Result] The 30 natural outcrop spring in Wudalianchi area were se-riously pol uted by nitrogen. Total nitrogen and nitrate nitrogen were the main forms of nitrogen pol ution. The content of total phosphorus and ammonia nitrogen were low. [Conclusion] The natural outcrop spring is mainly caused by agricultural non-point source pol ution.
