摘要/Abstract

摘要： 利用静态箱-气相色谱法连续两个生长季（2007—2008年）对小兴安岭典型修氏苔草（Carex schmidtii）沼泽和油桦（Betula ovalifolia）-修氏苔草灌木沼泽CO₂、CH₄和N₂O的排放通量进行野外原位观测。结果表明,除2008年灌木沼泽为N₂O的弱汇外,其他均为温室气体的排放源。除苔草沼泽生长季初期,CH₄与N₂O具显著负相关外,CO₂与CH₄、CO₂与N₂O及CH₄与N₂O均呈正相关,但显著性水平视不同湿地类型以及不同季节而定。

Abstract: CO₂,CH₄ and N₂O fluxes were measured using the technique of closed opaque chamber and gas chromatography system. The experiment was carried out during 2007—2008 growing seasons in field of Carex schmidtii marsh and Betulaovalifolia-Carex schmidtii shrub swamp ecosystems in Xiaoxing’an Mountains. The results showed that the two wetlands both were emission sources of greenhouse gases during growing seasons, except for the weak sink of N₂O in shrub swamps in 2008. Excepted for CH₄ and N₂O were negatively correlated in the early growing season of Carex schmidtii marsh, there was a positively correlation between CO₂ and CH₄ emission fluxes, CO₂ and N₂O emission fluxes, and CH₄ and N₂O emission fluxes. But the level was different in various wetlands or seasons.

Key words: CO₂ fluxes, CH₄ fluxes, N₂O fluxes, Carex schmidtii marshes, Betula ovalifolia-Carex schmidtii shrub swamp, Xiaoxing’, an Mountains
