在生物量调查的基础上,对南亚热带27年生观光木(Tsoongiodendron odorum)人工林生态系统的碳储量及分配格局进行了研究。结果表明:观光木人工林生态系统植被层生物量为101.26t·hm-2,乔木层生物量占86.90%;观光木的各器官碳素含量在426.5～496.9g·kg-1,大小排序为:树干>枝条>枯枝>根兜>粗根>树叶>中根>树皮>细根。观光木人工林生态系统总碳储量为180.49t·hm-2,其中0～80cm土壤层碳储量是植被层的2.67倍;乔木层年净固碳量为3.07t·hm-2·a-1,并主要以地上部分为主。
Based on the biomass survey, the carbon storage and allocation patterns of the plantation ecosystem of 27-year-old Tsoongiodendron odorum in the subtropical region were studied. The results showed that: the biomass of vegetation layer in the plantation ecosystem was 101.26t · hm-2 and the biomass of arbor layer was 86.90%; the carbon content of various organs of sightseeing tree species was 426.5-496.9g · kg-1, : Trunk> Branches> Withered branches> Roots pocket> Rough root> Leaves> Middle root> Bark> Fine root. The total carbon storage of sightseeing plantation ecosystem was 180.49t · hm-2, in which the carbon storage in 0-80cm soil layer was 2.67 times of that in vegetation layer, and the net carbon sequestration in tree layer was 3.07t · hm-2 · a-1 , And mainly based on the ground part.
