| 摘 要： | 采用野外调查取样和实验分析相结合的方法,研究黄土高原子午岭林区天然柴松林生态系统空间尺度上碳储量及分布特征。结果表明:1)植被层乔-灌-草不同器官含碳率范围为0.413 7～0.517 4 g/g,枯落层为0.187 2～0.500 3g/g,不同器官及层次间含碳率差异较大;土壤层有机碳含量随着土层深度的增加而递减。2)柴松林总储碳密度为236.04t/hm2,空间分布特征表现为土壤层(107.55 t/hm2)>植被层(95.20 t/hm2)>枯落层(33.29 t/hm2);总储碳量为1597万t,其中土壤碳库最大,为727万t,占总储量的45.52%,分别是植被层及枯落层碳库的1.14和3.22倍。

| Abstract: | Based on investigation and laboratory analysis,carbon storage and distribution characteristics have been studied on natural secondary forest of Pinus tabulaeformis fshekannesis in Ziwuling area of Loess Plateau.The results showed that: 1) the rate range of carbon content was 0.413 7-0.517 4 g/g and 0.187 2-0.500 3 g/g in vegetation layer(trees,shrubs and grasses) and litter layer respectively.Furthermore,great significance of carbon content had appeared at different organs and layer.Carbon content in soil l... |
