| 摘 要： | 在鸡公山天然落叶栎林中设置样地,调查分析了落叶栎林生态系统土壤碳密度和碳储量,测定了林下植被层和凋落物层碳储量,并用生物量方程法估测了乔木层各组分的生物量及碳储量.结果表明:落叶栎林生态系统总碳储量为156.60 t·hm-2,空间分布特征表现为乔木层(81.65 t·hm-2)>土壤层(66.13 t·hm-2)>凋落物层(7.50 t·hm-2)>灌木层(1.09 t·hm-2)>草本层(0.23 t·hm-2).在不同采样层次上碳含量存在明显差异.土壤层碳储量随着海拔升高而显著增加(p<0.05),随着土层深度增加而显著降低(p<0.05).

| Abstract: | Setting sample plot in Jigongshan mountain natural deciduous oak forest,the soil carbon density and storage in deciduous oak forests were investigated,the carbon storages of shrub,herb,and litter were measured,and the biomass and carbon storage of tree layers were further estimated by biomass equtions. The results suggested that the total carbon storage of hard wood oak forest ecosystem was 156. 59 t·hm- 2,and the carbon stroage of each layer was significantly different in the order of tree layer( 81. 65 t·hm- 2) > soil layer( 66.13 t·hm- 2) > litter layer( 7.50t·hm- 2) > shrub layer( 1.09 t·hm- 2) > herb layer( 0.23 t·hm- 2). Soil carbon stroage significantly increased with altitude,and decreased with depth( P < 0. 05). |
