•Dynamic change of soil erosion resistance were quantified.•Soil erosion resistance showed more spatial variation than temporal variation.•Mean weight diameter was the optimal index to describe the soil erodibility.•The critical shear stress was only affected by clay content.•Data strongly support a...
