摘  要:
木材含碳率是木材碳储量估算的重要因子之一,准确测定木材含碳率对于木材碳储量结果有着重要的意义。该研究在木材含碳率测定过程中,提出了利用生长锥取样的新方法,避免了以往取样过程中对树木和生态环境造成的破坏。选择小区域尺度帽儿山实验林场4种不同树种木材为试样进行含碳率的测定,共选择相同直径、不同生长环境和光照方向的160个样品进行测定。结果表明:针叶材整体含碳率高于阔叶材,生长环境和遗传因素对木材含碳率也存在一定影响。

摘  要:
The carbon content rate of timber is an important factor for wood carbon stock estimation,accurately measuring the carbon content rate of wood has an important significance for wood carbon stocks.During the process for determining the timber carbon content rate,a new method of sampling by the increment borer was put forward,which can avoid the damage to trees and eco-environment.Selecting 4 species of trees from Maoershan forest station,totally 160 samples(according to the same diameter,different growth environment and sunshine direction) of 4 species,the carbon content rate of them were determined respectively.The results showed that carbon content rate of softwood is higher than hardwood species,growth environment and genetic factors affected the carbon content rate of wood.
