摘要： 本文探讨了草原主要温室气体收支的现场观测方法。通过对内蒙古羊草草原生态系统三种主要温室气体N2O、CH4和CO2排放通量的现场观测,分析、讨论了三种气体排放通量的日变化特征,指出羊草草地N2O排放与CH4吸收之间存在的拮抗效应。

关键词: 温室气体, N2O, CH4, CO2, 排放通量

Abstract: The F1uxes 0f three important greenhouse gases(N2O,CH4 and CO2)were measured in sitevia closed chamber technique on July 8,l998. The characteristic of diurnal variation in those greenhousegases fluxes were analyzed and discussed.The results show that there was trade-off between N2O emission and CH4 consumpti0n by the steppe soil.
