摘　　要：根据近几年国内外文献资料 ,综合分析介绍了农业土壤N2O排放的进展情况。提出农业土壤中N2O的产生是在微生物的参与下 ,通过硝化和反硝化作用完成。影响N2O产生与排放的主要因素包括土壤特性 (理化性质和水热条件 )、气候条件 (温度、降水、光照 )和农业技术措施 (肥水管理、作物类型 )。深入研究农业土壤N2O排放与这些因素间的数量关系 ,客观估计区域或全球农业土壤N2O的排放总量并提出切实可行的减排措施乃是未来的研究方向。Nitrification and denitrification processes of microorganisms contribute to N2O production in the agricultural soils. Key factors influencing the production and emission of N2O are: soil characters including physicochemical properties and thermal-water conditions, climate including temperature, precipitation and solar radiation, and agricultural management such as fertilization and cropping system. It is recommended that further study be focussed on quantitative description between N2O emissions and these key factors, estimation of regional and/or global amount, and development of reducing N2O emission from agricultural soils in the future.
