Soil bulk density,surface hardness, 0~ 20cm hardness and capillary capacity were tested in grazing gradient in temperatural zone semi-arid steep. The soil type is dark sandy chestnut. Thc grazing intensity range is from 0 to 6. 67 shecps/ha. The research result showed: (1) It is limited (0~ 10cm)soil bulk density change influenced by grazing intensity. The mathematics model between soil bulk density and grazing intensity is Y . Soil compaction is the light grazing in summer (15~25 .July ) , the heavy grazin...
