Specific embodiment
As shown in figure 1, for outdoor portable wind erosion analog, by sample prescription peripheral frame, multi gear portable hair dryer, many
Root justifies chi and dust collection bag composition, and sample prescription peripheral frame is convenient for experimental calculation, preferably square-shaped frame, and its size is 1m*1m,
Many round chis are inserted on soil in sample prescription peripheral frame（Each chi deflation the thickness of the layer can be directly recorded, the later stage averages）,
Dust collection bag is provided with rear side of sample prescription peripheral frame, the blowing mouth of the collection port correspondence multi gear portable hair dryer of dust collection bag sets
Put, dust collection bag is close to be positioned over after sample prescription peripheral frame.
To prevent the dust for blowing afloat to be scattering into its elsewhere, sample prescription frame side shield can be vertically arranged in sample prescription peripheral frame both sides, be kept off
