Global warming has become an increasingly serious issue due to the build-up of greenhouse gases. Increasing the carbon sink of forests and the carbon storage of harvested wood products is an effective approach to alleviate the greenhouse effect. According to the theories and models on the carbon storage function of forest and harvested wood products, this study derives and improves accounting models and algorithm for the carbon pools of forest,soil and harvested wood products to evaluate the transition and transfer of carbon from forest carbon pool to harvested wood products carbon pool. Under the context of climate change and the current situation of the development of China' s forestry carbon pool,the study establishes a compound carbon measuring model including forest carbon pool and harvested wood products carbon pool based on a cascade industrial chain of Forest-Products,which contributes to the formation of criteria on measurement and evaluation for China' s forestry carbon pool. For this purpose, first of all, the study investigates the development status and internal mechanism of forestry carbon pool to offer theoretical support on the construction of structure in China' s forestry carbon pool system. It also provides logical methods to establish China ' s forestry carbon pool model after summarizing and comparing the corresponding mainstream of the methods and models created by domestic or foreign studies on forestry carbon pool evaluation. Secondly,analyzing the strengths and weaknesses on the evaluation of current China' s forestry carbon pool,and then concludes the creative evaluation path for forestry carbon pool in China. What' s more, combining and referencing many advanced thinking or methods such as adopting the ideas of Production Approach indicated by the Intergovernmental Panel on Climate Change to analyze the inflow and outflow of carbon during manufacture,producing and any other processes in this cascade industrial chain,which contributes to the formation of creative model on China' s forestry carbon pool as well as analyzing its system content. Finally,using mathematical language to describe the newly construction of China' s forestry carbon pool model, then analyzing its mathematical structure and doing formula derivation to establish the Forest-Products Carbon Model (FPCM).
