摘要
以山西太岳山自然保护区油松林(Pinustabulaeformis forest,PF)、辽东栎林(Quercusliaotungesis forest,QF)、油松辽东栎混交林(mixed forest,MF)为研究对象,计算了3种林分类型的碳储量及其在乔木层、灌木层、草本层、地表凋落物和0~20 cm土层中的分配比例.结果表明:PF、QF和MF的碳储量分别为123.01、153.53、132.93 t·hm~(-2),其地上碳储量分别占总碳储量的70.83%、60.94%、57.50%;地上碳储量以乔木层最高,其占总碳储量的比例在PF、QF、MF中分别是65.96%、58.07%、54.01%;3种林型灌木、草本和地表凋落物的碳储量较少,占总碳储量的比例不到5%;PF、QF、MF、0~20 cm土层有机碳储量分别为57.88、54.07、33.45 t·hm~(-2),占总有机碳储量的比例分别为33.04%、36.43%和23.85%;根系碳储量在PF、QF和MF中分别为2.04、1.92、1.49 t·hm~(-2),占其总碳储量的1.74%、1.26%、1.19%.太岳山3种林分类型碳储量的空间分配格局为地上乔木层、表层土壤、根系中的碳储量比例约为6∶3∶1.
Carbon( C) storage and its distribution among aboveground parts,including tree,shrub,herb layers,floor litter,and soils in the depth of 0-20 cm were investigated in Pinustabulaeformis forest( PF),Quercusliaotungesis forest( QF),and PF × QF mixed forest( MF) in Taiyue natural reserve. Results showed that total C stock averaged at 123.01,153.53,132.93 t·hm~(-2) in PF,QF,and MF,respectively,with C stock of aboveground parts accounting for 70. 83%,60. 94%,57. 50% of the total. And aboveground C stock most enriched in tree layer,peaking at 65.96%,58.07%,and 54.01% in PF,QF,and MF,respectively. Total C stock for shrub and herb layers and floor litter was less than 5% for each forest type. When it comes to underground part,C stock of soil in the depth of 0-20 cm was 33. 45,54. 07,57. 88 t · hm~(-2) in PF,MF,and QF,reaching 23. 58%,36. 43% and 33.04% of total C stock. Carbon stock for root was 2.04,1.92,1.49 t·hm~(-2) for PF,QF and MF,accounting for 1.74%,1.26%,1.19% of total C stock. Generally,C stock ratio among aboveground arborous layer,surface soil and root was 6 ∶ 3 ∶ 1 in temperate forest ecosystem in Taiyue Mountain.
