| 摘 要： | N2O是一种痕量气体,不仅能产生温室效应,而且对臭氧同温层有严重的破坏作用。随着人类活动的加剧,大气中N2O浓度每年以0.2%～0.3%的速度增加,N2O排放问题引起了人们的广泛关注。目前,对大气N2O排放的源与汇还缺乏全面认识,N2O在大气中增加量的40%～50%尚不知来源。综述了陆地生态系统N2O排放的自然源和人为源,分析了N2O排放的影响因素,并对今后N2O的研究提出了展望。

| Abstract: | Nitrous oxide is a trace gas and leads to greenhouse effect,but also destroy ozone stratosphere. With increasing human activities,atmospheric N2O is increasing at a rate of 0.2-0.3% each year.N2O emission arouse widely attention all over the world. Now, there is a lack of quantitative knowledge on the sink and source of nitrous oxide emission and about 40-50% of increased nitrous oxide in atmosphere is not clear.This paper summarizes natural and human emission source of nitrous oxide in terrestrial ecosystem ,analyses the main factors and prospects future research on nitrous oxide in future. |
