摘　　要：以山西中部油松生态系统为研究对象,设置样地测算乔木、灌木、草本及凋落物的生物量,钻取并分析0～100cm土层土样150份,最后依据相关方程,得出各层次及生态系统的含碳率和碳储量。结果表明:植被含碳率变化于42.88%～48.39%,凋落物含碳率平均为45.1%,0～100cm土层含碳率变化于0.22%～1.92%。油松生态系统平均碳储量为131.37Mg·hm-2,其中植被平均碳储量为46.37Mg·hm-2,占生态系统碳储量的35.3%,植被各层碳储量的顺序为乔木(44.30Mg·hm-2)>灌木(1.15Mg·hm-2)>草本(0.92Mg·hm-2);土壤平均碳储量为77.38Mg·hm-2,占生态系统碳储量的58.9%,是植被与凋落物碳储量的1.67倍和10倍,且随着土层深度的增加而递减;凋落物平均碳储量为7.61Mg·hm-2,仅占生态系统碳储量5.8%。Chinese pine forest ecosystem in the central Shanxi province was chosen as research object,we established sample plots and collected 150 soil samples to measure biomass carbon storage of trees,shrubs,and herbaceous plants,litter and soil.Then the carbon content and carbon storage of different layers and the forest ecosystem were obtained with the use of some equations.The result showed that the carbon contents in vegetation layers ranged from 42.88% to 48.39%,while in litter layer was 45.1% and in 0 ～ 100cm soil layers were 0.22% ～ 1.92%.In the study areas,carbon storage in Chinese pine forest ecosystem was 131.37Mg·hm-2,the carbon storage of vegetation was 46.37 Mg·hm-2,accounting for 35.3% of the entire carbon storage,their distributions in vegetation layers were ranked in order of tree layer（44.30 Mg·hm-2） shrub layer（1.15 Mg· hm-2） herbaceous plant layer（0.92Mg·hm-2）;the carbon storage of soil layer was 77.38Mg·hm-2,which represented 58.9% and was 1.67 and 10 times of vegetation and litter layers.Furthermore,it gradually decreased with the depth of soil;and the carbon storage of litter layer was 7.61Mg·hm-2,only accounted for 5.8% of the forests ecosystem carbon storage.
