Tillage erosion rates under conventional hoeing tillage on the linear slope were assessed using the digital elevation model (DEM), Trapezoid-step method and tillage erosion model. Erosion region and accumulative region appeared distinclty due to intense tillage erosion in the sloping farmland. Meanwhile, the field double-ring method was used to examine soil infiltration on a purple soil of the uncultivated plot, tillage erosiver region and accumulative region. The results showed that mean soil flux rate due to tillage erosion which obtained by DEM and Trapezoid-step method was 25.02 t ha-2 yr-1 on the linear slope. Meanwhile, the process of infiltration in the uncultivated land, tillage erosive region and accumulative region could be well described with the equation of Kostiakov （f=a·t-b）. Since soil compaction and depth of tillage layer changes significantly in the tillge erosive region and accumulative region, there were significant differences the process of infiltration between two regions. Soils in the tillage erosive region showed a significant reduction of initial infiltration rate, steady infiltration rate, and cumulative infiltration, resulting in that more serious water erosion occurred. However, tillage operation that decreases soil compaction will significantly increase infiltration and reduce water erosion.
