“…The TRIPLEX-GHG model (Peng et al, 2013) is based on the legacy of well-established and published models that include IBIS (Foley et al, 1996), DNDC (Li, 2000), TRIPLEX (Peng et al, 2002) and CASACNP (Wang et al, 2010). However, the scope of this study was only to introduce the development of the new wetland water table and the methanogenesis modules.…”

Abstract.A new process-based model TRIPLEX-GHG was developed based on the Integrated Biosphere Simulator (IBIS), coupled with a new methane (CH 4 ) biogeochemistry module (incorporating CH 4 production, oxidation, and transportation processes) and a water table module to investigate CH 4 emission processes and dynamics that occur in natural wetlands. Sensitivity analysis indicates that the most sensitive parameters to evaluate CH 4 emission processes from wetlands are r (defined as the CH 4 to CO 2 release ratio) and Q 10 in the CH 4 production process. These two parameters were subsequently calibrated to data obtained from 19 sites collected from approximately 35 studies across different wetlands globally. Being heterogeneously spatially distributed, r ranged from 0.1 to 0.7 with a mean value of 0.23, and the Q 10 for CH 4 production ranged from 1.6 to 4.5 with a mean value of 2.48. The model performed well when simulating magnitude and capturing temporal patterns in CH 4 emissions from natural wetlands. Results suggest that the model is able to be applied to different wetlands under varying conditions and is also applicable for global-scale simulations.

“…Linkages of existing models as a meta-model instead of spending time and money to develop a completely new model to represent the ecosystem is a global trend (Peng et al, 2002). As we have already introduced 3-PG, here we will introduce CENTURY and TREEDYN3, and then describe the TRIPLEX model.…”

“…It borrows the soil submodel from CENTURY, and the growth and yield components from 3-PG and TREENYD3. It has four major submodels: forest production submodel, soil C and N dynamics submodel, forest growth and yield www.intechopen.com submodel and soil water balance submodel (Peng et al, 2002). The TRIPLEX model uses the approach from 3-PG to calculate gross primary productivity (GPP),…”

“…Empirical growth and yield models are nowadays widely used to support decision making in practical forest management and forestry, when focusing on timber production (Peng et al 2002, Zhou et al 2005, Kangur et al 2007). However, they have usually been parameterised based on past forest inventory data, and they assume that the climatic conditions and the forest management are not changing in the future compared to the past.…”

Alam, A. 2010. Effects of forest management and climate change on energy biomass and timber production with implications for carbon stocks and net CO 2 exchange in boreal forest ecosystems. Dissertationes Forestales 117. 30 p. Available at: http://www.metla.fi/dissertationes/df117.htm ABSTRACTThe aim of this work was to investigate the effects of forest management and climate change on energy biomass (wood) and timber production with implications for carbon stocks and net CO 2 exchange in boreal forest ecosystems in Finland. First, the impacts of thinning on growth, timber production and carbon stocks under the current and changing climate were analysed by employing an ecosystem model for the whole of Finland over a 90-year period (Article I). Concurrently, the potential of energy biomass production with implications for timber production and carbon stocks under varying thinning and climate scenarios was studied (Article II). Thereafter, a life cycle assessment (LCA) tool for estimating net CO 2 exchange of forest production was developed (Article III), and it was applied in interaction with ecosystem model based simulations to study the impacts of different management regimes (initial stand density and thinning regimes) on energy biomass production and related CO 2 emissions at a stand level with a rotation length of 80 years (Articles III & IV).The results showed that the climate change increased the production potential of energy biomass and timber, and carbon sequestration and stocks over the whole of Finland, but, in a relative sense more in northern than southern Finland (Articles I & II). Decreasing basal area based thinning thresholds compared to the currently recommended ones, increased the harvesting of the annual average amount of timber compared to the annual average growth of stem wood, and reduced carbon stocks in the forest ecosystems (Article I). On the other hand, the use of increased basal area thinning thresholds concurrently increased energy biomass and timber production, and carbon stocks in the forest ecosystem regardless of climate applied (Article II). The development of the LCA tool made it also possible to estimate the net carbon exchange of the forest production (Article III). Based on the use of the LCA tool with the ecosystem model simulations, it was found that the impacts of management related emissions on net carbon exchange were small compared to the total ecosystem fluxes. It was also found that the increase in initial stand density compared to the conventional practice of 2000 seedlings ha -1 , not only increased the energy biomass production at energy biomass thinning, but also reduced management related CO 2 emissions of energy biomass production (Article IV).To conclude, the applied management substantially affects the net atmospheric impacts of production potential of forest ecosystems. The combined use of ecosystem model simulations and the LCA tool will together provide new insights for the analysis of ecologically sustainable energy biomass and timber production systems ...
