摘要
在兴安落叶松原始林试验区草类-落叶松林、藓类-落叶松林、杜香-落叶松林各设置2块标准地,在其中进行草本植物、藓类、灌木、乔木和枯枝落叶等地上生物量调查,根据实测数据建立生物量计算回归模型,计算各林型生物量与碳储量、平均生产力与年固碳量。结果如下：草类、藓类、杜香-落叶松林生物量分别为196.494 2t/hm^2、162.293 5t/hm^2、148.858 0t/hm^2,平均生产力为1.18t·hm^-2·a^-1-2.79t·hm^-2·a^-1之间;碳储量分别为95.8001t/hm^2、76.484 5t/hm^2、73.127 5t/hm^2,年固碳量为0.57t·hm^-2·a^-1-1.37 t·hm^-2·a^-1之间。
On the basis of set sample plots at the Larix gmelinii virgin forest,studied the overground biomass of arbor layer,shrub layer,herbage layer,moss layer and litter layer.Establish a biomass regression model by the measured data,then,calculated the biomass,carbon storage,mean productivity and carbon sequestration.The results were as follow： the biomass of the Grass-Larix gmelinii virgin forest,Bryaceae-Larix gmelinii virgin forest and Ledum palustre-Larix gmelinii virgin forest were 196.494 2t/hm^2,162.293 5t/hm^2 and 148.858 0t/hm^2,mean productivity were 1.18t·hm^-2·a^-1～2.79t·hm^-2·a^-1;the carbon storage were 95.8001t/hm^2,76.4845t/hm^2 and 73.1275t/hm^2,carbon sequestration were 0.57t·hm^-2·a^-1～1.37 t·hm^-2·a^-1.
