2009年7月12日至11月5日，采用静态箱法对内蒙古荒漠草原不同载畜率样地的温室气体通量进行了测定。不同放牧率并没有改变天然气通量的源汇和季节变化规律，荒漠草原生态系统对甲烷的吸收较弱，对二氧化碳的排放较弱荒漠草地碳通量主要受温度、水分、群落植被特征等因素的影响。
The greenhouse gas flux was measured using the static chamber method from July 12th to November 5th 2009 in the different stocking rate plots of the Inner Mongolia desert grassland.Based on the results of the field experiment,the different stocking rates didn't change the source and sinks of gas fluxes and seasonal variation patterns.The desert grassland ecological system absorbed the methane weakly and exhausted the carbon dioxide.Desert grassland output C element.The carbon flux of desert grassland was mainly affected by temperature,moisture,community vegetation characteristics.
