Effects of desertification on soil respiration and ecosystem carbon fixation in Mu Us sandy land
荒漠化对毛乌素沙地土壤呼吸及生态系统碳固持的影响

Desertification greatly affected the soil respiration and carbon fixation potential in arid and semi-arid area including the Mu Us sandy land of Northern China,and therefore changed the carbon circulation in regional or global scale.In order to reveal the temporal variations of soil respiration and their controlling factors,to understand the effect of desertification on soil respiration rate and the carbon fixation rate in Mu Us sandy land,the main desertification stages in this area were identified in this...
