摘要
通过调研四川省退耕还林工程实施现状,建立模型,预测未来60 a四川省退耕还林工程的碳汇潜力。采用经由森林清查人工林历史生长数据拟合的里查德方程(Richards equation)进行分树种生长量预测,依据文献调研所得有关参数计算相应的生物碳储量,结合碳排放、碳基线和碳泄漏的分析与估算,得出四川省退耕还林工程未来60a碳汇量。
Through investigations of the status of implementing returning farmland to forest in Siehuan Province, this paper sets up model and predicts the carbon sequestration potential （CSP） resulted from returning farmland to forest in Siehuan in next 60 years. The model to calculate CSP has been set and the Riehards Equation simulated from the historical growth data of plantation based on forests inventory is used to calculate the wood store of each tree species. The carbon stock in living biomass has been calculated from wood store by drawing into some proper parameter. Final outcome shows the CSP under returning farmland to forest in Siehuan Province in next 60 years by combining the consideration of carbon emission, carbon baseline and carbon leakage
