摘要
氧化亚氮(N2O)是大气中的一种痕量气体,同时也是一种重要的温室效应气体,并且它还可以和臭氧(O3)反应以致破坏臭氧层.其增温潜势大,滞留大气时间长,近年来成为全球关注的议题.农田土壤是N2O重要的源,中国是农业大国,研究农田N2O的产生机制、影响因素及其相应的减排措施,对于控制温室气体排放,维护生态平衡,改善我国人民的生存环境质量,无疑具有重要的现实意义.本文拟就目前国内外农田土壤N2O的产生机制、影响因素及相应的减排措施等研究的进展作一综述.
Nitrous oxide （N2O） is not only a trace gas, but also one of the important greenhouse gases. In the recent years, nitrous oxide draws the researcher attention by the understanding that this gas plays an important role in the chemistry of the stratosphere and the ozone layer destruction, its long life time in the atmosphere and a significant influence on the earth thermal balance by the absorption of long wave infrared radiation. Agricultural soil is one of the important sources of N2O.It is important to understand the production mechanisms and mitigation measures of the Nitrous oxide. In this paper, we will generally discuss about the relevant study progress of N2O emission in the recent years.
