中文摘要：

本文综述了近年来有关农业土壤NO排放研究的进展,包括NO的形成机制、采集与测定方法、排放量、影响NO排放的主要因素以及减少NO排放的有关措施等;在此基础上,提出了今后一段时期,我国农业土壤NO排放研究的重点仍然要更深入探讨农业土壤NO的产生和排放机制、主要影响因素与NO排放的定量关系、通过模型的建立估算不同区域农业土壤NO的排放量以及提出合理的减排措施.

英文摘要：

This paper reviewed the recent research progresses in NO emission from agricultural soils,including formation mechanism of NO,collection and measurement methods,emission amount,main influence factors on NO emission,and mitigation practices for NO emission.On this basis,it is suggested that during a future period investigation on NO emission from agricultural soils in China should be still focused on production and emission mechanism of NO,quantitative correlation between main influencing factor and NO emission,estimation of NO emission in different areas by means of modeling NO emission from agricultural soils.Some optimum practices for reducing NO emission were also proposed in this paper.
