摘　　要：对祁连山森林土壤容重及碳贮量研究表明：祁连山森林土壤总贮碳１０４４．５万ｔ，并且呈增加趋势，对大气ＣＯ２通过森林起“汇”的作用；乔木林土壤对大气ＣＯ２的现实作用大，灌丛林潜在作用大；人类经营活动通过影响凋落物的凋落和分解，对土壤碳产生较大的影响。The results of soil unit weight and carbon reserves of forestin Qilian Mountain indicated that total carbon reserves in forest soil was104.45 million tons,which play a 'collection' effect for carbon dioxide ofatmosphere.Tree forest soil had more realizable affect for the collection ofcarbon dioxide of atmosphere, and shrub forest had more potential effect.
