| 摘 要： | 为准确估计甘肃小陇山林区的碳库大小及碳汇功能,根据1 259块标准地和836株标准木资料,建立了锐齿栎等8种树种的各器官生物量回归方程,对小陇山不同林分的生物量进行了测定和研究.结果表明:小陇山林区锐齿栎、油松、栓皮栎、杨桦、落叶松、华山松、云冷杉、其他硬阔混交林等8类林分生物量依次为:84.047 2、 62.442 4、 81.774 7、 77.436 7、 68.998 2、 70.069 5、 96.486 5、 98.723 5 t/hm2; 各树种的单木生物量与胸径和树高之间均存在着紧密的相关关系;各种林分乔木层生物量与林分蓄积量,与林分平均胸径、平均树高及密度之间相关关系紧密.

| Abstract: | In order to accurately estimate the size of carbon pool and the capacity of carbon sink in the forest region of Xiaolong Mountains,Gansu Province,this paper established regression equations of organ biomass of eight tree species such as Quercus aliena var.acuteserrata etc.;besides,it measured and investigated the biomass of different forest stand types,based on the data analyses from 1 259 standard sample plots and 836 standard sample stems.The results showed that stand biomass of eight stand types in Xiaolong Mountains,including Q. aliena var.acuteserrata,Pinus tabulaeformis,Q.variabilis,Populus-Betula,Larix spp.,Pinus armandii,Picea-Abies,and hard broadleaved mixed forests,was as the followings:84.047 2,62.442 4,81.774 7,(77.436 7,) 68.998 2,70.069 5,96.486 5,98.723 5 t/hm~2.It also shows that the biomass of single log of each tree species is closely related with the trunk diameter and tree height;biomass of tree as well as stand volume are closely related with the average trunk diameter,average tree height and stand density. |
