摘　　要：通过对黄河包头段氨氮污染状况水质监测数据的时间和空间分布进行分析,发现黄河包头段氨氮污染近几年呈逐年下降的趋势,但污染还是较为严重;一年中6~10月氨氮含量较低,其他月份氨氮含量增高,且氨氮含量随温度的降低而增高。Based on the analysis of temporal and spatial distribution of monitoring water quality of ammonia-nitrogen pollution in Baotou section of the Yellow River,it was found in recent years,ammonia-nitrogen pollution showed a declining trend in Baotou section of the Yellow River,but the pollution was still very gravy.Ammonia-nitrogen content was lower during 6-10 months,its levels increased in other months,and the increasing content of ammonia-nitrigen was accompanied by reducing temperature.
