\begin{abstract}
Grassland runoff is related to soil and water conservation, but there
are few related studies. In this study, a simulated rainfall experiment
was carried out, and the results showed that: 1) The runoff depth
increases with the increase of rainfall intensity and decreases with the
increase of slope or cover, all of which can be described by linear
equations; 2). Soil specific gravity, root fractal dimension and grass
dry weight can explain 5.00\%, 31.08\%, and 6.64\%, respectively;3). The
NSE of the grassland erosion model established by rain intensity, flow
discharge and cover is 0.700, which is 0.142 larger than that of the
grassland erosion model established by rain intensity and flow
discharge.The research conclusions will help prevent and control floods,
improve water resource utilization and strengthen grassland erosion
monitoring.%
