- Title:
- Carbon Content and Storage of Mexican Cypress Plantation Forest in the Xuyi County
- 分类号:
- S718.5;X171.1
- 摘要:
- 选取盱眙县墨西哥柏人工林为研究对象，对其灌木层、草本层、枯枝落叶层、土壤层进行了碳储量研究。结果表明：灌木层枝、干、叶、根的含碳率依次48.92%，48.49%，49.74%和48.04%，器官含碳率大小表现为C叶 > C枝 > C干 > C根，草本层是地上部分含碳率大于地下部分含碳率，枯枝落叶层的含碳率表现为C叶 > C枝，土壤层的含碳率随着土壤深度的增加而降低，0—10 cm和10—20 cm土层之间土壤含碳率的差异性显著。墨西哥柏人工林生态系统现存碳储量67.31 t/hm2，其中灌木层1.21 t/hm2，占总碳储量的1.8%；草本层0.08 t/hm2，占总碳储量的0.12%；枯枝落叶层0.02 t/hm2，占总碳储量的0.03%；土壤层66 t/hm2，占总碳储量的98.05%，可见碳储量主要集中在土壤层中。
- Abstract:
- The Mexican cypress plantation forest was taken as a case. The carbon storage of shub layer, herbaceous layer and soil layer were investigated. the results showed that the branch, stem, leaf and root of shrub layer carbon contents is 48.92%, 48.49%, 49.74% and 48.04%,respectively, and the carbon contents of organs of shrub layer decreased in the order:was Cleaf > Cbranch > Cstem > Croot, for herbaceous layer the order was Cabove > Cbelow, and for litter fall layer the order was Cleaf > Cbranch. In the soil layer, the carbon content decreased with the increase of depth, with the most significant difference of carbon contents between the depth of 0—10 cm and the depth of 10-20 cm. Total existing carbon storage of Mexican cypress plantation forest ecosystem reached to 67.31 t/hm2, including the shrub layer 1.21 t/hm2, accounting for 1.8% of the total carbon; 0.08 t/hm2 in herbaceous layer, accounting for 0.12% of total carbon, 0.02 t/hm2 in litter layer, accounting for 0.03% of the total carbon and 66 t/hm2 in soil layers, accounting for 98.05% of total carbon, so carbon mainly concentrated in the soil layer.
