| 摘 要： | 以新疆亚高山草甸土为研究对象，研究了自由放牧和划区轮牧对土壤理化性质的影响。结果表明：短期改变放牧制度对草地土壤养分含量影响不显著，理化性质对其响应程度亦有所不同。轮牧土壤碱解氮、有机质的含量稍低于自由放牧，土壤速效钾和有效磷的含量均高于自由放牧。不同放牧制度对草地土壤容重、孔隙度、机械组成的影响不大。

| Abstract: | The effects of different grazing systems,including continuous grazing and rotational grazing,on soil physical and chemical properties of subalpine meadow soil were studied in the paper,based on grazing experiments in Nalati of Xinyuan Country,Xinjiang.The results showed that there was no significant effect on the soil nutrients for the short-term change of the grazing system,but the responses of soil physicochemical properties to the grazing system were still different.Compared with the continuous grazing,t... |
