| 摘 要： | 森林生物量、碳储量是评价森林生长状况的重要指标。通过野外样地调查及室内烘干称重等方法,研究了苏木山林场不同林龄华北落叶松人工林乔木层、灌木层、草本层生物量以及乔木层净生产力、碳储量积累特点和变化趋势。结果表明:幼龄林、中龄林、近熟林平均木的生物量分别为26.41 kg、32.70 kg、107.81 kg;林分生物量分别为43.66 t·hm^-2、79.88 t·hm^-2、125.83 t·hm^-2;灌木层和草本层生物量之和分别为1.44 t·hm^-2、1.19 t·hm^-2、0.95 t·hm^-2;乔木层净第一生产力分别为2.56 t·hm^-2·a^-1、3.07 t·hm^-2·a^-1、3.40 t·hm^-2·a^-1,碳储量分别为22.20 t·hm^-2、40.55 t·hm^-2、63.80 t·hm^-2。苏木山华北落叶松人工林生物量、碳储量随林龄增加而增大,各器官碳储量从大到小依次为干>根>枝>皮>叶。

| Abstract: | Biomass and carbon storage are important indexes to evaluate forest growth situation.Based on field survey and indoor drying weighting method in Sumushan Forest Farm,for Larix principis-rupprechtii plantation with different forest years,the biomass of arbor layer,shrub layer and herb layer and the accumulating characters and changing trend of net productivity and carbon storage of arbor layer have been studied.The results show that for young forest,middle-aged forest and nearly mature forest,the average tree biomass is 26.41 kg,32.70 kg and 107.81 kg,respectively,and the stand biomass is 43.66 t·hm^-2,79.88 t·hm^-2 and 125.83 t·hm^-2,respectively.The sum of biomass for shrub layer and herb layer is 1.44 t·hm^-2,1.19 t·hm^-2 and 0.95 t·hm^-2,respectively.The net primary productivity of arbor layer is 2.56 t·hm^-2·a^-1,3.07 t·hm^-2·a^-1 and 3.40 t·hm^-2·a^-1,and the carbon storage is 22.20 t·hm^-2,40.55 t·hm^-2 and 63.80 t·hm^-2,respectively.With the increase of forest year,the biomass and carbon storage of Larix principis-rupprechtii plantation increase.The order of carbon storage of each organ is stem>root>branch>bark>leaf. |
