In order to provide scientific and theoretical basis for control of water and soil loss of slope, soil anti-scourability for different land uses (shrub land, waste grassland, cultivated land and bare land) in Longbagou basin, the dry valley of upper Minjiang River was studied by the flume experiment, and soil erosion and sediment yield characteristic and its influencing factors were discussed. The results showed that the anti-scourability of surface soil under different land use patterns increased and assumed wavy variation along with scouring time; the anti-scourability followed the order of waste grassland, wheat land, shrub land, corn land, bare land; soil anti-scourability values and silt content has a significant negative correlation (r=-0.992, P<0.01), and sand content has a significant positive correlation (r=0.925, P<0.01).
