摘要:
 以张家口坝上张北县、沽源县的无性繁殖造林小黑杨为研究对象，根据生物量模型计算插条、断根和埋桩造林的小黑杨林分的生物量，利用碳储率算出含碳量，进而得出无性繁殖造林小黑杨的生产力和固碳量。结果表明：1）插条小黑杨地上部分生产力为1 425.73 kg·hm-2·a-1，其干、枝、叶的生产力分别为1 094.91、242.76 kg·hm-2·a-1和88.06 kg·hm-2·a-1；断根小黑杨地上部分生产力为1 048.86 kg·hm-2·a-1，其干、枝、叶的生产力分别为813.75、167.98 kg·hm-2·a-1和67.13 kg·hm-2·a-1；埋桩小黑杨地上部分生产力为780.23 kg·hm-2·a-1，其干、枝、叶的生产力分别为618.62、106.75 kg·hm-2·a-1和54.86 kg·hm-2·a-1。2）插条小黑杨干、枝、叶的固碳量分别为528.84、119.68 kg·hm-2 ·a-1和42.18 kg·hm-2·a-1，地上部分总固碳量为690.71 kg·hm-2·a-1。断根小黑杨干枝叶的固碳量分别为393.04、82.81 kg·hm-2·a-1和32.16 kg·hm-2·a-1，地上部分总固碳量为508.01 kg·hm-2·a-1。埋桩小黑杨干枝叶的固碳量分别为298.79、52.63 kg·hm-2·a-1和26.28 kg·hm-2·a-1，地上部分总固碳量为377.70 kg·hm-2·a-1。3）无性繁殖造林小黑杨的地上部分年平均每株生产力和年平均每株固碳量都表现为： 断根小黑杨>埋桩小黑杨>插条小黑杨。
Abstract:
 Taking Populus simonii×P.nigra afforested by different asexual reproduction methods (cutting,layerage,and stump burring ) in Zhangbei and Guyuan counties around Bashang region of Zhangjiakou as research object,its productivity and carbon fixation capacity were examined by calculating the related biomass. The results showed that 1)the productivities of aboveground parts, i.e., tree trunks, branches, and leaves were 1 094.91,242.76 and 88.06 kg·hm-2·a-1 (totally 1 425.73 kg·hm-2·a-1), respectively. For the second method, the corresponding values were 813.75,167.98,and 67.13 kg·hm-2·a-1 (1 048.86 kg·hm-2·a-1). For the third method, the corresponding values were 618.62,106.75 and 54.86 kg·hm-2·a-1 (780.23 kg·hm-2·a-1), respectively.2) The amounts of carbon fixation of the trunks, branches, and leaves for the first method 528.84,119.68,and 42.18 kg·hm-2·a-1(totally 690.71 kg·hm-2·a-1), respectively.For the second method, the corresponding values were 393.04,82.81,and 32.16 kg·hm-2·a-1（totally 508.01 kg·hm-2·a-1.And for the third one,the corresponding values were 298.79,52.63, and 26.28 kg·a-1·hm-2 (totally 377.70 kg·hm-2·a-1),respectively.3) Annual mean productivity and carbon fixation capacity of the three methods were in the order of the second method＞the third > the first.
