摘要
高寒人工草地牦牛放牧试验结果表明：①放牧强度对土壤有机制和有机碳含量有极显著的影响（P〈0．01），对土壤有机质的C/N比值有显著的影响（P〈0．05）；②0～30cm土壤有机制和有机碳平均含量与放牧强度分别呈显著（P〈0．05）和极显著（P〈0．01）的线性回归关系。
The result of grazing trial for yaks in alpine-cold artificial grassland showed：①Grazing intensity influenced very significantly on contents of soil organic matter and organic carbon（P 〈 0.01 ） and significantly on C/N of soil organic matter（P 〈 0.05） ;②There was a significant linear regression relationship between grazing intensity and content of soil organic matter （P 〈 0.05） and a extremely significant linear regression relationship between grazing intensity and average content of soil organic carbon （ P 〈 0.01）.
