Abstract: Based on the six runoff plots built at the soil and water conservation monitoring station in Fuling, the soil and water loss on cultivated purple soil slopes was investigated. The results show that plot runoff and sedimentation increase with increasing rainfall. Environmental rehabilitation reduces soil and water loss with only 0.41 kg·m^-3 sediment from 3.66 m³ runoff, an effective control measure of soil and water loss on cultivated purple soil slopes. On cultivated plots which in sequence with slope, evident positive correlations exist between runoff and rainfall, but with less evident correlation between sediment and rainfall. Runoff and sediment decreases with decreasing slope degree. 15° slope plough is most environmental friendly, but as to whether it is most suitable for cultivation in Fuling area is subject to further rainfall data analysis. In one strong rainfall observation, the sequence of soil nutrient loss is almost consistent with runoff and sediment. Runoff and sediment on monitoring plots with waste residue of building material are much higher than on other plots, indicating it is important to prevent soil and water loss on soil-water -conservation engineering.
