| 中文摘要: |
| 通过对通辽市典型人工林进行野外调查,获得通辽市典型人工林的生物量数据,并对碳密度
的分布特征进行分析。结果表明,3个树种混交的林分结构能提高林分结构的复杂程度,林分在垂
直结构中的空间利用性使得固碳能力得到提升,且树种复杂的林型在土壤固碳方面具有积极效果。
人工纯林和混交林的碳密度分别为42.73~107.73 t/hm2、48.49~182.06 t/hm2,不同林分中碳密度
的层次变化依次为土壤层>乔木层>灌木层(林)>草本层,枯落物和草本层的固碳能力基本相同。
通过计量分析人工林生态系统的碳密度,以期提高人工林的固碳能力,并实现森林质量的精准提
升,从而为“双碳”目标中碳储量的精准估算提供理论支撑。 |
| 英文摘要: |
| Through field investigations of typical plantations in Tongliao City, biomass data were obtained,
and the distribution characteristics of carbon density were analyzed. The results showed that the mixed
stands of three tree species could increase the complexity of stand structure, enhance the spatial utilization
of the stand in the vertical structure, and improve the carbon sequestration capacity, and the forest type
with complex tree species had a positive effect on soil carbon sequestration. The carbon densities of pure
plantations and mixed plantations were 42.73-107.73 t/hm2 and 48.49-182.06 t/hm2 respectively. The
hierarchical variations of carbon density in different stands were soil layer>arbor layer>shrub layer>herb
layer, with the carbon sequestration capacities of litter and herb layers being essentially the same. By
quantifying the carbon density of plantation ecosystems, this study aims to enhance the carbon sequestration
capacity of plantations and achieve precise improvement in forest quality, thereby providing theoretical
support for the accurate estimation of carbon storage in the context of the “dual carbon” goals. |
