农田生态系统氮、磷肥的环境效应

A Review of Researches on Environmental Effects of N and P Fertilizers in Agricultural Ecosystem

从氮、磷肥的施用对土壤环境、水环境、大气环境以及对农产品质量几个方面论述了氮、磷肥的过量施用对环境的影响,指出氮、磷肥在水体、土壤、大气、生物各子系统的环境效应并不一致,研究氮、磷肥的环境效应应综合分析各子系统的环境效应。

The effects of applying extra N and P fertilizers on environment were discussed from water environment, soil environment, air environment and agricultural product quality The results showed that the environmental effects of water, soil, air and biology were not identical. The effect of each single factor should be considered when research is done on the environmental effects of applying N and P fertilizers
