摘要
【目的】开展森林植被碳储量和碳密度研究对更准确的了解和把握森林碳储量及其空间分布特征具有重要意义。【方法】基于2019年森林资源二类调查数据,采用生物量转换因子法对江西铜鼓森林植被碳储量进行研究。【结果】研究表明:铜鼓县森林植被碳储量为4618.48×10^(3)t,平均碳密度为32.23 t·hm^(-2);碳储量主要集中在阔叶混交林和杉木林中,分别占比35.85%和20.95%;铜鼓县中龄林和幼龄林是碳储量的主要贡献者,占比达67.25%,具有巨大的碳汇潜力;从起源来看,天然林碳储量占84.92%,是铜鼓县森林碳储量的主体;就不同林种而言,水土保持林和短轮伐期用材林占总碳储量的比例最高,达到了92.08%。【结论】铜鼓县森林植被具有较大的碳汇潜力,本研究将为铜鼓县森林资源的经营管理和林业可持续发展提供参考。
【Objective】It is of great significance to study the carbon storage and density of forest vegetation for more accurate understanding of forest carbon storage and its spatial distribution characteristics.【Method】Based on the second-class survey data of forest resources in 2019,the carbon storage of forest vegetation in Tonggu county was studied by biomass conversion factor method.【Result】The results showed the carbon storage of forest vegetation in Tonggu county is 4618.48×10^(3)t,and the average carbon density is 32.23 t·hm^(-2).Carbon storage is mainly concentrated in broad-leaved mixed and Chinese fir forest,accounting for 35.85% and 20.95% respectively.In Tonggu county,mature and young forests are the major contributors to carbon storage,accounting for 67.25%,which has a huge carbon sink potential.From the origin,the natural forest carbon storage account for 84.92%,which is the main body of forest carbon storage in Tonggu county.In terms of different forest category,the proportion of soil and water conservation forest and short-rotation forest accounted for 92.08%of the total carbon storage.【Conclusion】In conclusion,the forest vegetation in Tonggu county has great potential of carbon sink.This study will provide reference for the management of forest resources and the sustainable development of forestry in Tonggu county.
