湖北省马尾松天然林碳储量及碳密度特征

摘要

We analyzed the carbon storage and carbon density including arbor layer , shrub layer, litter layer and soil of Pinus masos niana natural forests in Hubei Province with 87 plots.The total carbon storage and the average carbon density of Pi-nus massoniana natural forests were 1.10×108 and 121.16 t・ hm-2, respectively.The average carbon storage of arbor layer , shrub layer, litter layer and soil were 4.06×107, 1.26×106, 2.79×106 and 6.51×107, respectively, and the average carbon density were 44.82, 1.39, 3.08 and 71.87 t・ hm-2 , respectively.%选择87块马尾松天然林样地，系统调查乔木层、灌木层、枯落物层和土壤层碳储量和碳密度，评估湖北省马尾松天然林碳储量及碳密度现状。结果表明：湖北省2012年马尾松林总碳储量为1．10×108t，平均碳密度为121．16 t・ hm-2。其中：乔木层、灌木层、枯落物层、土壤层碳储量分别为4．06×107、1．26×106、2．79×106、6．51×107 t；碳密度分别为44．82、1．39、3．08和71．87 t・ hm-2。
