湖南省森林碳汇估算与评价

Estimation and evaluation of Hunan forest carbon sinks

作为二氧化碳等温室气体的主要吸收和储存者——森林资源,其固碳能力水平对经济社会的可持续发展具有重要意义。运用生物量清单法的理论和方法,定量评价了湖南森林碳汇量。研究结果表明:湖南省森林碳汇量大,森林碳汇密度高,严重依赖于自然环境和林业工程项目;同时,分析了森林碳汇量与碳密度、林业工程项目及产业能源消耗的关系,提出了增加森林资源碳汇、促进区域经济社会可持续发展的政策建议。

The forest resources,as the main absorption and storage of carbon dioxide and other greenhouse gases,its’ capability of carbon fixation gets great significance for the sustainable social and economic development.This paper uses the theories and methods of biomass inventory method to determine and evaluate the Hunan forest carbon sinks.And the results show that the Hunan forest carbon stocks is relatively rich,the forest carbon density is large,the potential of development is huge,but forest carbon sinks seriously depend on natural environment and forestry project.At the same time,this paper analyzes the relationship between forest carbon sinks and the density of forest carbon sinks,carbon forestry projects,industrial energy consumption.So based on this understanding,this paper put forward some suggestions as to increase the amount of forest carbon sinks and to promote the sustainable development of Hunan province’s economic and social.
