基于固碳效益的森林最优轮伐期的确定

Determination of Optimal Rotation Age for Forest Stands Based on Carbon Sequestration Benefits

简述了国外基于固碳效益的最优轮伐期的研究。大量研究表明,当考虑人工林的固碳效益时,轮伐期长短会受影响,并会随碳价、贴现率变化而变化,并且这种变化通常很灵敏。通过总结国内关于森林固碳效益方面的研究,推导出固碳效益的一般模型,并将其引入到Faustm ann最优轮伐期模型中,从而整理出基于固碳效益的最优轮伐期模型。

The paper deals with the studies on optimal rotation age for forest stands based on carbon sequestration benefits in foreign countries.Many researches show that the consideration of carbon sequestration benefits will have an effect on rotation age.The rotation age is quite sensitive to carbon price and discount rate.A general model for calculation of forest carbon sequestration benefits was deduced by analysis of the domestic researches on forest carbon sequestration benefits.Then,the model was introduced into the Faustmann model for the determination of optimal rotation age;thereby,optimal rotation models based on forest carbon sequestration benefits were created.
