Background technology
Soil erosion is global Significant Problems of Eco-environment, and sloping upland is the important source of soil erosion.Domatic
Soil water erosion process can be analyzed to raindrop impact and runoff washes away the destruction dispersive process to soil particle and runoff to soil
The handling process of grain.During slope water erosion, the runoff that earth's surface is formed generally carries a number of silt, along with run-off
Continuous increase, this sediment laden flow has stronger erosiveness to soil below.Whether pool according to sediment laden flow
Plume, domatic sediment laden flow can be divided into thin layer sediment laden flow and rill suspension current.Owing to thin layer sediment laden flow distribution area is big,
The silt of carrying is often the major part of the erosion caused by sloping surfaces, and being therefore simulated thin layer sediment laden flow is research runoff from upslope
The basis of husky Soil Under Conditions Erosion Law.
Slope water erosion process study at present simulates thin layer sediment laden flow frequently with Method of rainfall simulation.I.e. to test
District directly carries out artificially-simulated rainfall and obtains thin layer sediment laden flow；This method can preferably simulated rainfall produce runoff invade
Erosion, but operability is poor, and the run-off silt content of generation is uneven, and run-off and silt content are difficult to quantify, and is difficult to simulation simultaneously
The thin layer sediment laden flow of larger flow.
