| 摘 要： | 为精确估计秦岭火地塘林区油松群落乔木层的碳储量,在外业调查的基础上,采用TOC-VTH-2000A型TOC分析仪测定了油松(Pinus tabulaeformis)、华山松(Pinus armandi)、锐齿栎(Quercus aliena var. acuteserrata)、华北落叶松(Larix principis)干、皮、枝、叶、根的含碳率,结合已建立的乔木不同器官生物量模型,计算了不同树种各器官的碳储量和乔木层的碳密度,分析了不同含碳率下各树种各器官碳储量的差异.结果表明:不同树种各器官含碳率明显不同;在相同生物量下,以实测含碳率、0.45和0.50作为植物的平均含碳率计算的油松的干、皮、枝、叶、根,锐齿栎的枝,华北落叶松的皮、枝、叶、根的碳储量有显著差异;油松群落乔木层碳密度为6.594Mg·hm-2.
