摘要
综述了全球范围内氮素污染物(包括含氮气态化合物N2O、NO、NO2、NH3和NO3-)的排放源、流量、贮量和对环境的效应;同时,分析了氮素污染物与土壤、氮肥之间的关系。
This paper reviews the exhausting sources, fluxes, storage amounts and the effects on environment of the nitrogen pollutants(including gaseous compounds such as N 2O, NO, NH 3 and nitrate) on the global scale. Meanwhile, the relationships among nitrogen pollutants, soil, fertilizer nitrogen and NO 3 leaching are valuated.
