本文以美国东南部格鲁吉亚州为例，构建了一个二氧化碳排放权交易的林业盈利模式。采用蓄积量变动法、平均蓄积量法、吨年法和归还CO2信用额法计算了森林碳储量的CO2信用额。在此基础上，考虑引入排污权交易对采伐年限的影响，计算了采伐年限为10-50年时，造林利率在每5年内达到最大值时的CO2价格。造林利率最大值的采伐年龄为32年。在4种核算方法中，采伐年龄均随CO2价格的上升而缩短。在假定CO2交易价格的前提下，根据该模型的存量变化法和平均存储法，可以预测当前的采伐年龄。假设这一CO2价格，并使用吨年法和归还CO2信用额法，我们可以预测，目前的采伐年龄不会改变。
In this study, a forestry profit model for carbon dioxide (CO2) emission trading was constructed using southeast Georgia, USA, as the model area. The value of CO2credits regarding forest stores of carbon was calculated using the stock changing method, the average storing method, the ton-year method, and the returning CO2credit method. Based on this model, the CO2price at which an afforestation interest rate reaches its maximum in each 5-year interval at a cutting age of 10–50 years was calculated, considering the influence on the cutting age by introducing emission trading. The cutting age at which an afforestation interest rate reaches its maximum was 32 years. The cutting age shortened with the rise of CO2price in all four accounting methods. Assuming the dealing CO2price, we can forecast what the present cutting age will be according to the stock changing method and the average storing method in regard to this model. Assuming this CO2price and using the ton-year method and the returning CO2credit method, we can forecast that the present cutting age is not going to change.
