| 摘 要： | N2O在大气中的浓度仅为CO2的浓度的千分之一左右，但在同等浓度的情况下温室效应却是CO2的200~300倍；它在大气层中的光化学产物会与臭氧反应，从而损耗平流层的臭氧。N2O的环境效应引起人们的关注，许多国际气候变化研究项目都把其列入重要研究内容。通过对过去40年的相关研究工作进行综合分析，阐述N2O在海洋中的分布规律和其影响因素、产生的机制、它的海气通量及其影响因素，从而揭示N2O的海洋生物地球化学循环过程以及这一过程对全球氮循环的贡献。

| Abstract: | The concentration of nitrous oxide in the atmosphere is only two orders of magnitude lower than that of Carbon dioxide, however, its green house effect is about 200-300 times higher than that of carbon dioxide. So it has been considerably concerned in the past decades and lots of work have been carried out. A review of the study on biogeochemical cycle of nitrous oxide in oceans for the past decadets is presented here. The vertical distribution of nitrous oxide in oceans, their impact factors, as formation and removal mechanisms will be discussed in more detail. The N2O cycles in oceans will play a significant role in the global biogeochemical cycle. |
