Abstract: | This study examined the biomass and carbon pools of the main ecosystem components in an age sequence of five Korean pine plantation
forest stands in central Korea. The C contents in the tree and ground vegetation biomass, coarse woody debris, forest floor,
and mineral soil were estimated by analyzing the C concentration of each component. The aboveground and total tree biomass
increased with increasing stand age. The highest C concentration across this chronosequence was found in the tree branch while
the lowest C concentration was found in the ground vegetation. The observed C contents for tree components, ground vegetation,
and coarse woody debris were generally lower than the predicted C contents estimated from a biomass C factor of 0.5. Forest
floor C content was age-independent. Total mineral soil C content appeared to decline initially after establishing Korean
pine plantations and recover by the stand age of 35 years. Although aboveground tree biomass C content showed considerable
accumulation with increasing age, the relative contribution of below ground C to total ecosystem C content varied substantially.
These results suggest that successional development as temporal factor has a key role in estimating the C storage in Korean
pine plantation forests. |
