【摘要】 以内蒙古红花尔基樟子松林国家级自然保护区樟子松人工林为研究对象,采用实测法对樟子松不同龄级人工林碳密度、碳储量及其分配特征进行了研究。结果表明:(1)樟子松人工林碳储量随林龄增加而增加。(2)樟子松人工林各碳层储量变化规律为:地下>地上,土壤层>植被层>枯落物层。(3)樟子松人工林各碳层储量中土壤层碳储量占比最大,且0—30cm土层碳储量占比在76.97%—80.18%之间,呈表层聚集现象。(4)乔木层碳储量主要集中在树干,表现为碳净积累特征。未来通过采用合理的人工抚育及科学管理措施,维持和增加土壤碳收入,充分利用其生长特性,对于维持生态系统碳平衡起着极其重要的作用。更多还原

【Abstract】 In this study, Pinus sylvestris var. mongolica plantation in Honghuaerji National Nature Reserve was selected as the research object to determinate carbon storage and distribution characteristics of carbon storage, by using the field measurement method. The results showed that :(1) Carbon storage of Pinus sylvestris var. mongolica plantation increased with the increase of forest age.(2) The variation rule of carbon layer storage in Pinus sylvestris var. mongolica plantation was as follows:underground > overground, soil layer > vegetation layer > litter layer.(3) Among the carbon storage in each layer of Pinus sylvestris var. mongolica plantation, the soil layer accounted for the largest proportion, the proportion of carbon stock in the 0-30 cm layer ranged from 76.97% to 80.18%, with the phenomenon of surface aggregation.(4) The carbon storage of tree layer was mainly concentrated in the trunk, which was characterized by net accumulation of carbon. Therefore, maintaining and increasing soil carbon income and fully utilizing its growth characteristics by adopting reasonable artificial cultivation and scientific management measures will play an important role in maintaining the carbon balance of the ecosystem.更多还原
