摘要
[目的]研究新安江流域黄山段氮、磷污染特征,为新安江流域生态补偿机制提供一定的参考。[方法]沿新安江流域黄山段布设了15个采样点,分别于丰水期、平水期、枯水期进行样品采集,并用分光光度法测定了样品中氮、磷等污染物的含量,分析新安江流域黄山段氮、磷污染特征。[结果]2013年新安江流域黄山段水质良好,氮、磷污染程度较低,总体能达到地表水Ⅲ类水质标准,但存在季节性差异和地域性差异。[结论]水质下降主要是由农业面源污染造成的,可以从农业管理方面加强治理。
[Objective]The research aimed to study the characteristics of nitrogen and phosphorus pollution of Xin＇an River basin in Huangshan section,which provides the references for ecological compensation mechanism of Xin＇an River basin. [Method] Along the Xin＇an River basin in Huangshan section emplaced 15 sampling points,respectively,in the wet season,the normal season and the dry season for sample collection,the content of the sample in nitrogen and phosphorus of Xin＇an River basin in huangshan section were determined by spectrophotometry,the characteristics of nitrogen and phosphorus pollution were analyzed. [Result] In 2013,the water quality of Xin＇an River basin in huangshan section is good,the degree of nitrogen and phosphorus pollution is low,the overall surface water can reach Ⅲ water quality standard,but there were seasonal variations and regional differences. [Conclusion]The water drop was mainly caused by the agricultural non-point source pollution,we can be managed from agriculture to improve governance.
