根据2007年吉林省汪清县境内东北部金沟岭林场的8个阔叶次生林标准地的调查数据,就其中7种主要乔木(DBH≥4cm)的地上碳储量及其伴随径级和树高等级的分布特征进行了研究。结果显示:1)地上碳储量大小排列为桦木(20 675.902 kg/hm2)>色木(7 065.584 kg/hm2)>椴树(4 740.284 kg/hm2)>山杨(3 777.076 kg/hm2)>水曲柳(3 440.81kg/hm2)>云冷杉(2 430.327kg/hm2)>红松(1 625.146kg/hm2)。2)在地上碳储量径阶分布方面,红松和云冷杉区别于阔叶树,碳储量曲线很平稳,在各径阶内碳储量没有较大变化。3)7种主要乔木地上碳储量随树高等级变化表现为单位面积的碳储量的分布沿高度级的增加而成倍增长,至一个峰值后,又随高度的增加而下降,整个变化趋势呈现一个近似正态的峰状曲线。5种阔叶树树干碳储量占总地上碳储量的比例随树高高度的增加而减少,而针叶树红松和云冷杉的树干碳储量比例随树高高度的增加而增加。
According to the survey data of eight broad-leaved secondary forest sites in Jingouling Forest Farm in northeast of Wangqing County, Jilin Province in 2007, the above-ground carbon storage and its accompanying diameter and tree height classes of seven major tree species (DBH ≥ 4cm) The distribution characteristics were studied. The results showed that: 1) Aboveground carbon stocks were arranged in the order of birch (20 675.902 kg / hm2)> color wood (7 065.584 kg / hm2)> lime tree (4 740.284 kg / hm2)> aspen (3 777.076 kg / hm2) Manchurian ash (3 440.81 kg / hm2)> Fir fir (2 430.327 kg / hm2)> Korean pine (1625.146 kg / hm2). 2) In terms of the above ground carbon storage, the Korean pine and Chinese fir differ from the broad-leaved tree in that the carbon storage curve is stable, and there is no significant change in carbon storage in each order. 3) The distribution of carbon storage per unit area of aboveground tree carbon stocks in seven main tree species changed exponentially with the increase of tree height. After reaching a peak, the distribution of carbon stocks decreased with the height increase. A nearly normal peak shape curve. The proportion of carbon stocks in all broad-leaved tree species to total above-ground carbon stocks decreased with the increase of tree height, but the proportion of tree carbon storage in coniferous and red fir trees increased with the height of tree height.
