- 摘要:
- 以内蒙古赤峰市敖汉旗黄花甸子流域的试验区中栽植山杏、小叶杨的样地土壤为研究对象,通过现场采样,分别采集15个土壤剖面,225个土壤样品进行分析,以期研究土壤有机碳垂直分布规律。结果表明:除小叶杨样地外,不同林地土壤有机碳含量及密度随土层深度加深显著降低,土壤有机碳储量主要集中在40 cm以上的土层。
- Abstract:
- aking of Populus simonii?and?Siberian Apricot? soil as the research objects,through field sampling,15 soil profiles were collected,225 soil samples were analyzed in order to study the vertical distribution of soil organic carbon rule.The results showed that except Populus simonii like extraterrestrial,soil organic carbon content and density decreased with soil depth,soil organic carbon reserves mainly concentrated in 40 cm above the soil.
