以克鲁伦河下游地区典型草原为研究对象,以传统游牧作为对照,研究探讨了围栏放牧草场利用方式下土壤物理性质变化规律,其研究结果如下：土壤含水量为游牧区〉打草场区〉轮牧区;土壤容重为轮牧区〉打草场〉游牧区;在夏营盘0～10 cm土层中孔隙度的比较结果为：游牧区〉打草场区〉轮牧区。在冬营盘各土层中土壤孔隙度比较结果是,游牧区〉打草场区〉轮牧区。土壤砂粒含量为游牧区〈打草场区〈轮牧区,细粉粒含量游牧区、轮牧与打草场区间均有显著差异,夏营盘和冬营盘的粘粒含量为轮牧区〈打草场区〈游牧区。

Taking the typical steppe in the downstream region of Kelulun River as the research object and traditional nomadism as control, the changing law of soil physical properties with the grassland utilization pattern of fence grazing has been studied. The results show that the soil water content is nomadic area 〉 clipping pasture area 〉 rotational grazing area, the soil bulk density is rotational grazing area 〉 clipping pasture area 〉 nomadic area. In summer quarter, the soil porosity in 0 - 10 cm layer is nomadic area 〉 clipping pasture area 〉 rotational grazing area. In winter quarter, the soil porosity in each layer is nomadic area 〉 clipping pasture area 〉 rotational grazing area. The soil sand content is nomadic area 〈 clipping pasture area 〈 rotational grazing area. There is obvious difference for fine silt content among nomadic area, clipping pasture area and rotational grazing area. And the clay content in summer quarter and winter quarter is rotational grazing area 〈 clipping pasture area 〈 nomadic area.
