“…We estimated the biomass C stocks with species-specific growth functions and BCFs (biomass conversion factors). In contrast, Li et al (2010) and Choi and Chang (2004) estimated the biomass C stocks by multiplying stemwood volume with forest type-specific (coniferous, deciduous, and mixed) and constant biomass expansion factors (BEFs). Variable BEFs could overestimate biomass C of a young forest compared to constant BEFs (Guo et al, 2010).…”

“…Based on the national forest inventory (NFI) and statistical data, the biomass C stocks of South Korean forests over the past decades were estimated (Choi and Chang, 2004;Fang et al, 2014;Li et al, 2010). While this approach could determine the net C change in biomass, dead organic matter C stocks were excluded due to the lack of observed dead organic matter C stock data.…”

“…Averaged over the entire 1954-2012 period, the annual C balance was 8.3 Tg C yr −1 . Compared to the national fossil-fuel-based C emissions data during the period 1954(Boden et al, 2011, South Korean forests annually offset 13.4 % of the South Korean fossil fuel C emissions during that period. The time series of NBP increased over the simulation period and the change in NBP showed an upward trend (Fig.…”

Abstract.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 nationalscale 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.

“…The magnitude of forest biomass plays a key role influencing the global carbon cycle and assisting in meeting greenhouse gas emission targets (Ciais et al 2008, Li et al 2010b, Nabuurs et al 2010. With a large number of statistically valid plots, forest inventories have been recognized as appropriate data for identifying the size and spatial patterns of forest biomass at a regional or national scale (Schroeder et al 1997, Choi et al 2002, Son et al 2007b, Guo et al 2010, Li et al 2010b.…”

Biomass expansion factors, which convert timber volume (or dry weight) to biomass, are used for estimating the forest biomass and accounting for the carbon budget at a regional or national scale. We estimated the biomass conversion and expansion factors (BCEF), biomass expansion factors (BEF), root to shoot ratio (R), and ecosystem biomass expansion factor (EBEF) for Quercus mongolica Fisch. and Quercus variabilis Bl. forests based on publications in Korea. The mean BCEF, BEF, and R for Q. mongolica was 1.

Carbon accumulation by Pinus sylvestris forest plantations after different periods of afforestation in a semiarid sandy ecosystem

The carbon pool is changing in afforestation ecosystems, which vary in their duration since establishment, in many semiarid sand regions. Understanding this is important for the management of the planted forest. The present study explored the dynamics of afforested forest carbon pool in a semiarid sandy ecosystem, northwest China. We studied afforested forests of pine (Pinus sylvestris) of five afforestation ages (20, 30, 40, 50, and 60 years since planting, and bare sand as control), the carbon storage and carbon sequestration rate of the forest aboveground biomass layer, surface litter layer, and soil layer (0-50 cm) were calculated, and the soil water content and soil organic carbon of 0-400 cm soil depth were measured. The results showed that the carbon sequestration rate was highest after 20-30 years, with 0.58 Mg C ha −1 yr −1 in the soil layer (0-50 cm). We found a rate of 0.13 Mg C ha −1 yr −1 in the surface litter layer, and a rate of 20.79 Mg C ha −1 yr −1 in the forest aboveground biomass layer. The carbon storage of the forest aboveground biomass layer was highest after 30-40 years, and the carbon storage of the surface litter increased with time. In the soil layer, the carbon storage at 0-10 cm depth was highest after 60 years, the carbon storage at 20-50 cm depth increased soon after afforestation and then decreased afterward with increasing afforestation ages with the maximum for 20-50 cm occurring after 30-40 years. The total carbon storage [the forest aboveground biomass layer, surface litter layer and soil layer (0-50 cm)] was higher when afforestation ages reached around 30 years, after that it decreased with increasing afforestation age. Our research improves the understanding of the P. sylvestris forest ecosystem carbon sequestration in a semiarid sandy area.
