RDA analysis of the relationship between soil wind erosion intensity (WEI 6 m/s, wind erosion intensity of 6 m/s; WEI 9 m/s, wind erosion intensity of 9 m/s; WEI 12 m/s, wind erosion intensity of 12 m/s; WEI 15 m/s, wind erosion intensity of 15 m/s) and other soil factors (EC, electric conductivity; BD, bulk density; OM, organic matter; SP, soil porosity; SS, soil sand particle size composition; SSI, soil silt particle size composition; SC, soil clay particle size composition; SW, soil water content; TN, total nitrogen; SA>0.25, > 0.25 mm soil aggregate content; SSS, soil surface strength) constrained by freeze-thaw (FTC, freeze-thaw cycle) environment variables.
