摘要
以南山林场为例,对天山云杉林碳储量进行研究。结果表明:南山林场的总碳储量为332664.4305t,碳密度为59.5492 tC/hm2,高于全国的平均水平;针叶林碳储量占全林场碳储量的96.16%,而天山云杉的碳储量就占全林场的95.67%;成龄林的碳储量占全林场的95.09%;由此说明天山云杉是该林区碳储量的主要来源,但该林区正处于碳积累速率下降的成熟阶段,要加大对成熟林中幼树更新以及幼龄林的人工抚育的力度。以确保在森林碳储量急剧下降时,幼龄林已成长起来,使该林区的碳储量处于较稳定的状态。
The carbon storage of Picea schrenkiana forest of south mountain forest was studied. The results showed that ： the total forest biomass carbon storage in South mountain forest is 332664. 4305 t. The average carbon density of forest is 59. 5492tC/hm^2 , higher than the national average level ;the carbon storage of conifer for- est accounts for 96.16% of the total forest biomass carbon storage, Picea schrenkiana accounts for 95.67% of the total forest biomass carbon storage in the forest. Mature forest accounts for 95.09% of the total forest biomass carbon storage. This note that ： Picea schrenkiana is the main source of carbon storage in the forest, but this forest is in a decline in the rate of carbon accumulation mature stage. It is necessary to intensity update young trees in the mature forest and artificial upbringing to young forest, make sure that when the forest carbon storage decline sharply, the young forest has to grow up, so that this forest reserves of carbon storage in a more stable condition.
