森林碳汇经济价值评估研究——以福建省为例

Study on Economic Value Assessment of Forest Carbon Sequestration——Taking Fujian Province as an Example

森林碳汇是中国政府应对气候变化的重要策略.福建省作为重点林业大省,具有发展林业的优越条件.如何评价福建省现有森林碳汇经济效益,对于推动福建省森林碳汇交易市场的建立和完善具有重要意义.本文运用森林蓄积量扩展法评估福建省森林碳储量,用市场价值法评估森林碳汇经济价值.研究结果表明,福建省森林碳汇潜力巨大,森林碳储量由1978年的28186.91万t增长到2018年的84500.07万t;森林碳汇量经济价值先下降后上升,2018年在92.36~150.66亿元之间,较1978年增长了两倍.福建省应不断发展森林碳汇资源,从而推动全国森林碳汇交易市场的发展.福建省应从不断深化林权制度改革,加大科研投入,加大森林碳汇宣传力度和建立一套适用地方区域的森林碳汇计量体系4个方面入手,提出发展森林碳汇的对策和建议.

Forest carbon sequestration is an important strategy for the Chinese government to cope with climate change.Fujian,as a major forestry province,has the advantages of developing forestry.How to evaluate the economic benefits of forest carbon sequestration is of great significance to the economic transformation and upgrading of Fujian Province.Therefore,this paper evaluates the forest carbon sequestration and economic value of Fujian Province with the method of forest stock expansion.The results show that the potential of forest carbon sequestration in Fujian Province is huge.The forest carbon sequestration increased from 281.8691 million tons in 1978 to 845.0007 million tons in 2018.The economic value of forest carbon sequestration decreased first and then increased.In 2018,the economic value of forest carbon sequestration in Fujian Province was 92.36-150.66 billion yuan,a threefold increaseover that in 1978.The constant growth of the resources of forest carbon sequestration in Fujian has promoted the development of the forest carbon sequestration market of the whole country.Finally,the paper points out that Fujian Province should deepen the reform of theforest tenure system,increase investment in scientific research,increase propaganda on forest carbon sinks and establish a set of forest carbon sink measurement system suitable for the local areas,which is of great significance to the development of forest carbon sequestration in Fujian Province.
