| 摘 要： | 以新疆天山中段高寒草甸为研究对象，分析了高寒草甸不同植被群落类型地下生物量、土壤有机碳（SOC）的垂直分布特征。结果表明：地下生物量随深度增加均逐渐减少，表现为总的T字形趋势分布，主要分布在0～10cm深的土层中，95％～98％根系分布在0～5Ocm内。不同草甸类型的土壤有机碳含量均随深度的增加呈现下降趋势，表现为总的T字形趋势分布。土壤有机碳含量分布明显深于根系的分布深度，三种草甸类型0～20cm土壤有机碳含量分别为34％、58％、49％。

| Abstract: | This study analyzed soil organic carbon and underground biomass, carbon distribution in major types of alpine meadow along the middle range of Tianshan mountain. Results indicate that the underground biomass content of alpine meadow in Bayanbulak is dropping off as increase of depth. In addition to this, the underground biomass was mostly distributed in the 0 - 10cm soil depth in the three plant communities with a ＂T＂ shape distribution feature. The distribution of soil organic carbon is deeper than underground biomass. The soil organic carbon of alpine meadow is dropping off as increase of depth and mostly distributed in the 0 - 10cm depth in the three plant communities with a ＂T＂ shape distribution feature. The soil organic carbon of 0 - 20cm of whole section of three types meadow was about 34%, 58%, 49%. |
