气候变化问题已成为国际社会关注的热点问题之一,为了在全球范围内寻求有效措施减缓气候变暖,碳汇经济的发展已成为必然趋势。文章在系统分析碳交易情景下森林碳汇收益实现对林地收益的影响机理基础上,选取杉木作为代表性树种,基于浙江省实地调查数据,引入杉木生长模型以及改进的Faustmann模型,模拟分析碳交易情景下最佳轮伐期以及林地收益的变化。研究发现,在碳交易情景下,在当前碳价格下,森林的最佳轮伐期不会发生变化,林地效益会有所增加,但是随着碳价格上升森林的最佳轮伐期发生变化,林地效益显著增加。
The issue of climate change has become one of the hot issues of concern to the international community. In order to seek effective measures to reduce global warming, the development of carbon economy has become an inevitable trend. Based on the systematic analysis of the mechanism of the impact of forest carbon sinks on the return of forest land under the system of carbon trading, the paper selected Chinese fir as a representative tree species, introduced fir growth model and improved Faustmann model based on the field survey data of Zhejiang Province, and simulated the carbon trading Scenario Best Rotation and Woodland Yield Changes. The study found that in the carbon trading scenario, under the current carbon price, the optimal rotation period of forest will not change and the benefit of forest land will increase. However, as the optimal rotation period of forest changes with the increase of carbon price, The benefit of woodland increased significantly.
