华北落叶松人工林碳汇功能的研究

Carbon-sink function of artificial Larix principis-rupprechtii plantation

  • 摘要: 以河北省木兰林管局14~59年生华北落叶松人工林为对象, 研究树木不同器官和林分不同组分水平的生物量与碳储量。结果表明, 华北落叶松树干碳储量在树木总储量中所占比重最大, 林地土壤和林木碳储量所占林分碳储量的比重最大。华北落叶松人工林林分碳密度为平均206.02 t·hm-2;林木碳密度为27.58 t·hm-2, 林地土壤碳密度为157.14 t·hm-2。以林木蓄积量(M)为基础的林木生物量(W)与碳储量(C)的拟合方程为:W =10.210 1+ 0.732 1M, C=5.188 4+0.373 6M;以林龄(A)和优势木平均高(H)为基础的林地土壤碳密度(Soc)拟合方程为:Soc=-24.635 6-5.606 1A+14.936 0H+0.439 8AH。在此基础上计算得出, 木兰林管局华北落叶松人工林总碳储量约为571.43×104 t, 其中林木生物量约150.00×104 t、碳储量约为76.49×104 t, 土壤碳储量约435.85×104 t。

     

    Abstract: Plantations of 14~59-year old Larix principis-rupprechtii in Mulan Forest Farm of Hebei Province were selected and both biomass and carbon storage in the tree organs and the components of the plantation analyzed. Carbon storage in the stem of L. principis-rupprechtii forms the highest proportion of the plant total carbon storage. The proportions of carbon storage of soil and trees are highest in the plantation.L. principis-rupprechtii carbon density is 206.02 t·hm-2, while those of the trees and soils are 27.58 t·hm-2 and 157.14 t·hm-2 respectively. The fitted equations for carbon storage (C) and forest biomass (W) at growth stock (M) are W = 10.210 1 + 0.732 1M, C = 5.188 4+0.373 6M. That for soil carbon density (Soc) at forest age (A) and dominant tree average height (H) is Soc = -24.635 6-5.606 1A + 14.936 0H + 0.439 8AH. Accordingly, total carbon storage in Mulan Forest farm is 571.43×104 t, basic tree biomass and carbon storage are 150.00×104 t and 76.49×104 t respectively, while soil carbon storage is 435.85×104 t.
