摘　　要：本文以甘肃祁连山国家级自然保护区乔木林为研究对象,基于森林资源规划设计调查资料,分析了该保护区乔木林的生物量、碳密度及碳储量。结果表明:(1)保护区乔木林平均生物量和碳密度分别为127.67 Mg·hm^(-2)和62.48 Mg C·hm^(-2),总生物量和碳储量分别为2336.53×10^(4)Mg·hm^(-2)和1143.58×10^(4)Mg C;(2)保护区主要优势树种云杉和圆柏的单位面积生物量分别为140.70 Mg·hm^(-2)和89.57 Mg·hm^(-2),碳密度分别为68.94 Mg C·hm^(-2)和43.42 Mg C·hm^(-2),森林碳储量分别为947.04×10^(4)Mg C和118.73×10^(4)Mg C,分别占保护区总森林碳储量的82.81%和10.38%,其他树种组分布面积和碳储量相对较小。研究结果对认识祁连山地区森林生态系统碳循环及减少区域碳收支评价的不确定性提供了一定的依据和借鉴意义。Based on the forest inventory data,the biomass,carbon density and carbon storage of arboreal forest in Qilianshan National Nature Reserve in Gansu Province were analyzed.The results showed that:(1)The average biomass and carbon density of arboreal forest were 127.67 Mg·hm^(-2)and 62.48 Mg C·hm^(-2);the total biomass and carbon storage were 2336.53×10^(4)Mg and 1143.58×10^(4)Mg C,respectively.(2)The biomass per unit area of Picea asperata and Sabina chinensis were 140.70 Mg·hm^(-2)and 89.57 Mg·hm^(-2),seperatively;the carbon density was 68.94 Mg C·hm^(-2)and 43.42 Mg C·hm^(-2);the forest carbon storage were 947.04×10^(4)Mg C and 118.73×10^(4)Mg C,accounting for 82.81%and 10.38%of the total forest carbon storage,respectively.The distribution area and carbon storage of other tree species groups was relatively narrow.The results of this study provide a basis and reference for evaluating the carbon cycle of forest ecosystem and reducing the uncertainty of regional carbon budget in Qilianshan.
