Based on indoor experiment under simulated rainfall

the characteristics of splash erosion by rain2 drops in typical soil and water loss regions of China are analyzed and the relationships between splash erosion and soil physical and chemical properties are discussed.Results show that splash erosion amount is affected obviously by soil physical and chemical properties.The splash erosion amount of black soil samples is the lowest because of their high aggregate content and aggregate stability.The splash erosion amount of loess soil samples collected from Dongsheng City

Inner Mongolia is the highest because they contain high content of sand particles easily to be splashed.The other loess soil samples

red soil samples

and purple soil samples correspond to the medium splash erosion amount because of the majority of silt particles or high content of micro-aggre-gates.Except for black soil sample and loess soil samples collected from Dongsheng City

Inner Mongolia

soil crust is developed in other soil samples under simulated rainfall

so

raindrop splash rate fluctuates with time.
