Relationships between CO 2, CH 4 and N 2O concentrations and fluxes in Antarctic tundra were studied systematically under natural conditions of Antarctica.
在南极苔原 ,首次系统地研究了近地面CO2 、CH4、N2 O浓度及通量的相互关系 ,结果表明 :天气条件对三种温室气体浓度日变化影响较大 ;在天气较晴稳及雪天条件下 ,CO2 与CH4、N2 O浓度日变化存在明显的消长关系 ;而在雨天这三种气体浓度日变化趋势基本一致 ;整个夏季CO2 与CH4浓度变化趋势基本一致 ,而N2 O却与二者浓度的变化趋势相反 ;另外 ,在雨、雪天气条件下CH4、N2 O通量日变化存在消长关系 ,整个夏季二者的通量变化也存在明显的消长关系 ;南极苔原土壤对CH4主要起着汇的作用 ,对N2 O主要起着源的作用 。
