| 摘 要： | 通过对云南省不同区域桉树的典型取样,测定计算了桉树不同径阶的含水率、生物量和生物量扩展因子(BEF)。结果表明:桉树地上部分平均含水率为53.42%,低于云杉、云南松,高于桦木、木荷、栎类;桉树生物量扩展因子(BEF)平均值为1.23,小于云南省已经测定的5个树种的BEF值,小径阶桉树BEF值略大于大径阶BEF值。研究结果对于提升森林碳汇的精确计量具有积极作用。

| Abstract: | The water content,biomass and Biomass Expansion Factor(BEF)of Eucalyptus in different diameter stages were measured and calculated through the typical sampling in different regions of Yunnan Province.The results showed that the average water content of the above ground part of Eucalyptus was 53.42%,which was lower than that of Picea asperata Mast.and Pinus yunnanensis,which was higher than that of Betula,Schima superba and Quercus;the average value of the biomass expansion factor(BEF)of Eucalyptus was 1.23,which was less than that of the five tree species measured in Yunnan Province,and the BEF value of small-diameter Eucalyptus was slightly higher than that of large-diameter Eucalyptus.The results of the study have a positive effect on improving the accurate measurement of forest carbon sink. |
