Abstract
This study was conducted to examine the biomass and net primary production, stem density and biomass expansion factors of Pinus densiflora in Gochang regions. The mean age of Pinus densiflora in both stands was 10 and 48 years. The dry weights (kg/tree) and aboveground biomass (Mg/ha) were 8.59 and 17.55 for 10 years young stand, 166.66 and 122.05 for 48 years old stand. The total biomass (Mg/ha) including the above and belowground were 21.48 and 154.16 in both age stands. The proportion of stem biomass, stem bark biomass and root biomass increased from the young stand to the old stand while on the leaf biomass and branch biomass, tend to decreased. The net primary production of aboveground biomass (Mg/ha) and belowground biomass were 6.30~6.95 for the young stand and 11.61~13.19 for old stand. The stem density ($g/cm^3$) was 0.338 for young stand while on the other hand, 0.448 for old stand was observed. The above and total biomass expansion factors were 2.304~2.508 and 1.318~1.644 in each age stands, respectively.
