| 摘 要： | 对黄河水系1960年至2000年期间氮污染监测数据的分析表明，干流河水氮污染的程度自上游至下游有升高的趋势；不少支流氮污染的程度大大高于干流。在工业不发达的农业地区，河水总氮与氨氮的最高浓度大多出现在丰水期；在工业相对发达的地区，河水氨氮与总氮的最高浓度大多出现在枯水期；有一部分站点河水总氮与氨氮浓度的年内变化无明显规则，近40年来黄河水系氮污染程度不断上升，1990s年代以后的上升趋势更为显著。

| Abstract: | A study has been carried out to analyze the monitoring data of nitrogen pollution of the Yellow river basin form 1960s to 2000s.The results indicate as follows:The contents of nitrogen in the Yellow river mainstream have a raising trend from the upper reaches to the lower reaches;The contents of nitrogen in many tributaries are much higher than that in mainstream;Seasonal variances of nitrogen content vary with watersheds and showed three kinds of variance;The nitrogen content of the river water showed an increasing trend during the recent 40 years,especially after 1990s. |
