| 摘 要： | 针对苏南太湖流域无机体，高氮量施肥方式，造成氮肥利用率下降、水环境污染日益严重这种现象，研究了不同氮肥施用水平下水稻的产量、氮肥利用率及氮肥水环境损失。并在以下研究结果的基础上，引入环境经济学的Ｃｏａｓｅ原理和主效益比较合理的水稻施肥量，相应的经济、生态２适宜产量为７３７９．５～７５４８．６ｋｇ／ｈｍ＾２。

| Abstract: | In Tai Lake watershed the crop yield increasing has been more and more depended upon the increasing application of chemical fertilizer.The nitrogen utilization efficiency(NUE) has greatly decreased,and the water in Tai Lake is more and more polluted.We studied the rice yield,nitrogen utilization efficiency,nitrogen leaching amount at different level of nitrogen fertilizer using in paddy rice field.The results show that with the Coase Theory of Environmental Economics and the Marginal Revenue Analysis Theory... |
