森林碳汇收益的实证分析——以广东省杉木林为例

【摘要】：以Hartmann模型为基础,扩展成考虑木材的经济效益,生物量碳库、死生物质碳库(DOM)以及林产品碳库的碳汇效益的最优轮伐期模型。并以广东地区的杉木林为例,比较在不同碳价、不同利率以及考虑不同碳库时的最优轮伐期及林地期望值。结果表明,在当前的碳汇价格下,考虑碳汇效益后的林地期望值会增加,但最优轮伐期保持不变。当碳汇价格为200元每吨时,最优轮伐期才会开始延长。利率的变化对最优轮伐期的影响不明显,但对林地期望值的影响很大。
[Abstract]:Based on the Hartmann model, the optimal rotation model was developed to consider the economic benefits of wood, biomass carbon pool, dead biomass carbon pool (DOM) and carbon sink benefit of forest products. Taking the Chinese fir forest in Guangdong as an example, the optimal rotation period and the expected value of forest land were compared under different carbon prices, different interest rates and different carbon pools. The results show that under the current carbon sink price, the expected value of forest land after considering the benefit of carbon sink will increase, but the optimal rotation period will remain unchanged. When the carbon sink price is 200 yuan per ton, the optimal rotation time will start to prolong. The change of interest rate has no obvious effect on the optimal rotation, but has a great effect on the expected value of forest land.
