| 摘 要： | 通过对银川地区1991～2000年的地下水水质动态监测数据分析发现其地下水氮污染严重,其中
尤以氨氮污染最为严重,对其氮污染的成因作进一步分析得出:引起潜水氮污染的主要因子是农田大量施
用化肥和地面污水下渗,引起承压水氮污染的主要因子是大量开采承压水造成的潜水对其越流补给,最后
提出了相应的防治措施。

| Abstract: | By analyzing the monitoring data of the quality of groundwater at Yinchuan Area from 1991 to 2000, this paper concludes
the current situation of nitrogen pollution is serious, especially ammonia pollution.moreover, concludes the factors that the phreatic
aquifer is polluted by nitrogen is the excessive use of chemical fertilizerin the farmlands and the leakage of the surface polluted-water
and the factor that causes the confined aquifer to be polluted by nitrogen is that the excessive exploiting the confined aquifer causes
increased phreatic water recharge to the confined aquiter. The corresponding measures of preventing nitrogen pollution are presented. |
