五大连池天然露头泉氮磷污染特征研究

Study of Nitrogen and Phosphorus Pollution Characteristics of Wudalianchi Natural Outcrop Springs

[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 pollution of 30 natural outcrop spring in Wudalianchi,which provides a theoretical basis for the sustainable development and utilization and protection of Wudalianchi natural mineral resources. [Method]Choosing 30 natural outcrop spring representatives in different region,samples were collected in low water period,normal water period,wet period respectively,the content of nitrogen,phosphorus and other contaminants in the samples were determined,the pollution characteristics of nitrogen and phosphorus in Wudalianchi natural outcrop spring were analyzed. [Result] The 30 natural outcrop spring general in Wudalianchi area were seriously polluted by nitrogen,total nitrogen and nitrate nitrogen is the main form of nitrogen pollution,the content of total phosphorus and ammonia nitrogen is low. [Conclusion] The natural outcrop spring polution was mainly caused by agricultural non-point source pollution.
