观光木人工林生态系统碳储量及其分布格局
Carbon storage and its allocation in an artificial Tsoongiodendron odorum ecosystem in southern subtropical region of China
摘要
Abstract
Based on the biomass investigation, this paper evaluated the carbon storage and its allocation in a 27-year-old Tsoongiodendron odorum plantation ecosystem in southern subtropical region of China. In the ecosystem, the total biomass of vegetation layer was 101.26 t ? Hm-2 , and the biomass of tree layer occupied 86. 90%. The carbon storage in various organs of the trees ranged from 426.5 to 496.9 g ? Kg-1, with the order of trunk > branch > dead branch > root tip > coarse root > leaf > middle root > bark > fine root. The total carbon storage of the ecosystem was 180.49 t ? Hm-2, and the carbon storage in 0-80 cm soil layer was 2.67 times of that in vegetation layer. The annual net carbon sequestration of the tree layer was 3. 07 t ? Hm-2 ? A-1, mostly in aboveground part.关键词
