| Forests play an important role in the global carbon (C) cycle, and the South
Korean forests also contribute to this global C cycle. While the South Korean
forest ecosystem was almost completely destroyed by exploitation and the
Korean War, it has successfully recovered because of national-scale
reforestation programs since 1973. There have been several studies on the
estimation of C stocks and balances over the past decades in the South Korean
forests. However, a retrospective long-term study that includes biomass and dead
organic matter C and validates dead organic matter C is still lacking.
Accordingly, we estimated the C stocks and their changes of both biomass and
dead organic matter C during the 1954–2012 period using a process-based model, the
Korean Forest Soil Carbon model, and the 5th South Korean national forest
inventory (NFI) report. Validation processes were also conducted based on the
5th NFI and statistical data. Simulation results showed that the biomass C
stocks increased from 36.4 to 440.4 Tg C at a rate of 7.0 Tg C yr−1
during the period 1954–2012. The dead organic matter C stocks increased from 386.0 to
463.1 Tg C at a rate of 1.3 Tg C yr−1 during the same period. The
estimates of biomass and dead organic matter C stocks agreed well with
observed C stock data. The annual net biome production (NBP) during the
period 1954–2012 was 141.3 g C m−2 yr−1, which increased from −8.8 g C m−2 yr−1
in 1955 to 436.6 g C m−2 yr−1 in 2012. Because of the small
forested area, the South Korean forests had a comparatively lower
contribution to the annual C sequestration by global forests. In contrast,
because of the extensive reforestation programs, the NBP of South Korean
forests was much higher than those of other countries. Our results could
provide the forest C dynamics in South Korean forests before and after the
onset of reforestation programs. |
