Abstract:: In order to examine the effect of freeze-thaw on soil erosion at different crop straw removal rates, three different removal rates at 0, 50%, 100% were set in three experimental sites in Kansas from 2011 to 2013. Measured parameters include erodible fraction (EF; aggregates<0.84 mm), geometric mean diameter (GMD) and random roughness (RR). The results showed that straw stubble could effectively reduce wind erosion under the effects of freezing and thawing; the EF value of soil increased and the GMD value and RR value decreased with the increase of the removal rate of straw; After freezing and thawing in 2011—2012, the increase rates of EF were 149%，185%，16% under the treatment of the 100% removal in Norcatur， Colby and Scott City， respectively, 40%， 152%，-28% under the treatment of the 50% removal, and 29%， 47%， 9% under the treatment of 0 removal; fallow has the positive effect on enhancing the ability of soil to resist wind erosion. These results have certain reference values for the research on suitable straw removal rate in the seasonal freezing and thawing area which is prone to soil erosion in China.
