摘　　要：采用１５Ｎ盆栽试验，研究化肥氮的去向，在定量水平上对氮的去向作出基本评估。根据上海郊区化肥施用的数量和种类，得出了化肥氮进入水体的数量（１．４万余．ｔ）和对上海郊区非点源污染的影响，揭示了招致化肥氮污染的主要问题，并提出了预防化肥氮污染的对策。The movement of nitrogen from chemical fertilizers applied was investigatedby pot experiment with 15N isotope. The quantitative evaluation of the nitrogen movementstate was made;according to the application levels and varieties of chemical fertilizersapplied;the amount of chemical fertilizer-derived nitrogen entering water bodies was about1.4 ten thousand tons and the influence on the non-point-source pollution was determined;revealing the main problem which leads to the pollution of chemical fertilizer-derivednitrogen. And then;the countermeasures of controlling nitrogen pollution was proposed.
