| 摘 要： | 以赤峰市杨树人工林为研究对象,对不同立地、不同林龄、不同林种杨树生物量、碳储量进行研究,结果表明:杨树人工林生物量随着树龄、胸径、树高的增长而增加,各个器官的生物量也不相同,干的生物量最大,叶的生物量最小,生物量依次顺序为:干根枝叶。树干的平均碳含量最大,为471.00 g/kg,根为461.14 g/kg,枝为468.00 g/kg,叶最小,为446.20 g/kg,不同器官的含碳率大小排序为树干树根树枝树叶。杨树人工林胸径与单株碳储量,树高、胸径与生物量、单株碳储量模型均符合乘幂模型,模型拟合率均大于80%。杨树人工林乔木层平均碳储量为37.783 t/hm2,赤峰地区杨树人工林乔木层碳储总量为26 539 627.38 t。 |

| Abstract: | In this paper, taking Populus spp. plantation in Chifeng as the research object,the biomass and carbon storage of Populus spp. with different ages and different forest categories in different sites have been studied. The results show that the biomass of Populus spp. plantation increases with the increase of tree age,dbh and height. The biomass of each organ is different ,the biomass of stems is the maximum ,the biomass of leaves is the minimum, the order is the biomass of stems 〉 the biomass of roots 〉 the biomass of branches 〉 the biomass of leaves. The average carbon content of stems is the maximum,reaching to 471.00 g/kg. The average carbon content of roots is 468.00 g/kg. The average carbon content of leaves is the minimum, reaching to 446. 20 g/kg. The sequence of carbon content rate of each organ is stem 〉 root 〉 branch 〉 leaf. The model of dbh and carbon storage per plant accords with power model, the same with the model of height, diameter, biomass and carbon storage per plant, with the matching rate over 80%. The average carbon storage in arbor layer of Populus spp. plantation is 37. 783 t/hm2, the total carbon storage in arbor layer of Populus spp. plantation is 26 539 627.38 t in Chifeng. |
