The Carbon Sink Model of Forest Afforestation in Taiwan
In these two decades, the greenhouse effect has resulted in significantly global warming problem catching the attention of the world. The reduction of greenhouse gases has been in accord to delay the earth damage so that the Kyoto Protocol was endorsed in 1997 and legally valid since 2005. It admitted the afforestation is one of the decrement ways of major greenhouse gas ? carbon dioxide (CO2). Taiwan governmental policy encourages forest afforestation, too. The 2006 IPCC (Intergovernmental Panel on Climate Change) guidelines for greenhouse gases inventory provided the carbon sink may calculate the aboveground biomass from forest. However, the carbon sink increment from plantation forestry is substantially not only from the aboveground biomass and underground tree roots, but the falling branches and leaves and soil carbon sink addition for comprehensive forest ecological system. In this study, the carbon sequestration was estimated by summation of the carbon sink (Ctree) from perennial woody plants with tree species and annual tree volume increment and soil carbon sink (Csoil) from literature. From the results, the carbon content of 518.76 kg of Taiwan incense-cedar and 718.74 kg of Taiwan acacia was calculated from Table 2. The hardwoods may sequester higher carbon that Taiwan acacia of 380.31 ton/ha was the best, Formosan ash and Taiwan zelkova of 345.11 and 311.05 ton/ha, respectively at age of 20 years that Taiwan incensecedar is 237.94 tonClia by IPCC model estimation. The conceptual carbon sink model was developed for tree afforestation and soil carbon sink as Csink Ctree + Csoil in Taiwan. Thus, the tree afforestation conceptual model can provide the planning tools for carbon sequestration and estimation of carbon sink amounts for auditing and carbon emission trading in the future. However, the uncertainty of estimation from the model such as growing time of tree species, area conditions, climate, pest as well as soil depth and density was not considered which may affect the carbon sink estimation demanding for further research.
