- 摘要：通过对黄河水系干、支流1980-1990-1997-1999年河水氮污染水质监测数据进行分析,发现:(1)自流域上游至下游,各主要支流河水氮污染有增加的趋势,造成干流河水氮污染沿程亦呈增加的趋势;(2)点源污染对黄河干、支流河水氮污染的贡献较大,但在1990-1997年间,流域河水氮污染的点源面源之比有降低的趋势,干流潼关站河水中总氮的点源与面源之比由1990年的2.7降至1997年的1.8;(3)黄河干、支流河水氨氮、总氮的含量在1980-1990-1997-1999年间存在明显的加速上升趋势,主要是由流域废污水排放量和氮肥施用量的增加所致.
- Abstract：A study has been carried out to analyze the monitoring data of nitrogen pollution of the Yellow River basin in 1980,1990, 1997 and 1999.The results indicate as follows: (1)The nitrogen content of the tributaries showed an increasing trend from the upper basin to the lower basin of the Yellow River, which led to the increasing trend of nitrogen concentration of the mainstream from the upper reaches to the lower reaches; (2)Nitrogen in the river water of the mainstream and the tributaries of the Yellow River was mainly attributed to point source. The ratio of point to non point sources decreased from 2.7 in 1990 to 1.8 in 1997 for total nitrogen of river water at Tongguan Station; (3) The ammonium nitrogen content of river water showed an accelerated increasing trend in the mainstream and the tributaries during 1980-1990-1999, which was caused by the increase of waste water discharge and nitrogenous fertilizer application in the Yellow River basin.
