摘　　要：根据黄河兰州段近十几年的氮、磷数据,运用污染指数法,分析了黄河兰州段的氮磷污染现状。结果显示,在1996-2009年时间变化表现为:(1)2001年及2007年正常外,其余年份黄河兰州段总磷的一次浓度值均超过了其相应的浓度标准值;(2)2003-2009年总氮含量均超过《地表水环境质量标准》(GB3838-2002)中的Ⅴ类标准,属于严重超标。空间变化如监测的5个断面,得出总磷含量和总氮含量指标,针对此结果,分析了原因并提出了相应的控制措施。According to the nitrogen and phosphorus data,the paper uses the pollution index method,analyzes the nitrogen and phosphorus situation of the Yellow River in Lanzhou in the last decade. The results show that: in 1996- 2009,except 2001 and 2007,the total phosphorus concentration was larger than the corresponding concentration of the standard's in other years. The total nitrogen content Were seriously overweight between 2003 and 2009; According monitoring to data of five sections,each section's phosphorus concentration was lower than the surface water environmental quality standard limits. Total nitrogen content exceeds the corresponding standard limits in the environmental quality of surface water( GB3838- 2002),and most of them were higher than the class V standard limits in 2003- 2009. The paper analyzes the reasons and puts forward the corresponding control measures.
