Description :
By scouring experiments, the changeable process and characteristics of sediment yield in the hillslope-gully side erosion system with different coverage degrees and spatial locations of grass were studied. It is showed that the proportion of sediment yield from the gully side increased in an exponential relationship with the increase of grass coverage degree. When the grass was located on the lower position of hillslope, the influence for accelerating gully erosion is the greatest.
