摘要: 在野外实地调查(灌草层、枯落物层和土壤层)的基础上,结合相关乔木树种生物量回归模型(乔木层),研究了瓦屋山林场森林的碳密度及碳储量的分配特征。结果表明:瓦屋山林场的平均碳密度为101.72 t/hm2,碳密度由高到低分别为:乔木层(55.37 t/hm2)、土壤层(41.89 t/hm2)、枯落物层(4.92 t/hm2)、灌草层(0.32 t/hm2)。碳储量为144 820 t,其分配与碳密度一致,从高到低依次为:乔木层(79 204.55 t)、土壤层(59 927.77 t)、枯落物层(5 292.07 t)、灌草层(395.78 t),分别占研究区总碳储量的54.69 %、41.39 %、3.65 %和0.27 %。林分密度大、林龄高和土壤层薄、石砾含量多是瓦屋山林场森林的主要特点,也是影响该区碳分配格局的主要原因。

Abstract: Using the allometric biomass models for trees and field investigation of understory plants and soils, carbon density and carbon storage of main forest types in Wawushan Forest Farm were studied. The results indicated that, the carbon density in the forest ecosystems was averagely 101.72 t/hm2, being ranked in the order of tree layer (55.37 t/hm2), soil layer (41.89 t/hm2), litter layer (4.92 t/hm2), herb and shrub layer (0.32 t/hm2). The total carbon stock of the forest was 144 820 t, and distribution in the four layers was 79 204.55 t (54.69 %, tree layer accounting for 54.69 % of the total carbon stock, the same followed)in tree layer, 59 927.77 t (41.39 %) in soil layer, 5 292.07 t (3.65 %) in litter layer and 395.78 t (0.27 %) in shrub and herb layer, respectively.
