Effect of grazing on soil structure and consequences for soil mechanical and hydraulic properties in Inner Mongolia

摘要：

Animal trampling can strongly affect soil physical properties.Destruction of soil structure caused by animals leads to increase in soil bulk density followed by an increase in surface runoff.Grazing can cause changes in pore functions which affect the hydraulic properties of the soil.Stresses exerted by trampling can also lead to changes in soil mechanical strength.The soil physical properties can be affected much more when considering arid climate conditions.The objective of this study was to investigate how the animal trampling can affect soil physical (hydraulic and mechanical) properties in an Inner Mongolia grassland ecosystem with different grazing intensity, with different moisture conditions.
