Abstract:: Through rainfall simulating in laboratory,and observation splash erosion rate on soil surface,this study intended to disclose the impact of Polyacrylamide on soil splash erosion rate.The results showed that PAM could change soil splash erosion rate,and the effect of PAM with different concentration was different.Moreover the effect of crust on splash erosion was predominant with the rainfall continuing.At the beginning of rainfall,PAM could reform soil structure and increase the stabilization of soil aggregates,so soil splash erosion rate was low.With rainfall continuing,erosion rate was increased greatly.But,when soil crust of surface was developed,splash erosion rate was greatly decreased because of the increasing anti-erodibility of soil surface.
