| 摘 要： | 兰州市马滩地下水源地多年的水质临测资料表明,NO_3~-对地下水的污染呈日益严重的发展趋势,这种污染趋势与水源地环境条件的改变和恶化有着密切的关系。通过分析可以明显地看出,造成地下水NO_3~-污染的根本原因是农田化学氮肥的大量施用。

| Abstract: | The data of ground water quality in Mutan, Lanzhou City, show that NO3- pollution is getting worse. It is found that a close relation exists between the pollution tendency and environmental deterioration in the water-supply-source site. By analysis, the essential cause of NO3- pollution in ground water is derived from fertilizing the farmland around with a huge amount of nitrogenous manure. |
