3.2 Variation of SIC density with stand age
The statistical results of SIC density in different stand ages are shown
in Table 2. The variation of SIC density for MS, 5yrs, 11yrs, 22yrs, and
46yrs ranged from 0.37 ~ 0.57 kg
m-2γ0.51 ~ 1.05 kg
m-2γ0.59 ~ 1.08 kg
m-2γ0.60 ~ 1.28 kg
m-2, and 0.68 ~ 1.35 kg
m-2γIt can be seen from the mean values that SIC
density showed an overall increasing trend with stand age.
