| 摘 要： | 氧化亚氮(N2O)是仅次于二氧化碳(CO2)和甲烷(CH4)的重要温室气体.由于人类活动对土地的影响导致河流系统中氮的可利用性增加,河流生态系统的N2O排放量正日益增长.本文对国内外河流水体N2O溶存浓度和饱和度、水-气界面排放通量及沉积物-水界面交换通量等数据进行了收集,并总结和分析了河流生态系统中N2O的产生机制及主要影响因子.

| Abstract: | Nitrous oxide (N2O) is the third of most important greenhouse gases after carbon dioxide (CO2) and methane (CH4) in the atmosphere. The influence of human activities on land lead to an increase in the availability of nitrogen in river system, and the emission of N2O from rivers increased accordingly. This paper collected data of N2O dissolved and saturated concentration in river water and the emission flux at water-air interface and sediment-water interface, summarized and analyzed the production mechanism of N2O in river ecosystem and the main influence factors. |

| Keywords: | river nitrous oxide concentration emission flux water-air interface sediment-water interface production mechanism impact factor |
