In order to investigate the effects of flow intensities, slope gradient and fractal dimension of erosion sediment particles on soil erosion on slope surface of accumulation body, three soils (aeolian sandy soil, red soil and Lou soil) and four flow intensities (8, 12, 16 and 20 L/min) were selected. Field runoff scouring simulation experiments were carried out on three slopes (28°, 32° and 36°). The results showed that:(1) The interaction of flow intensity and slope had the greatest influence on the average velocity of slope. The velocity of slope flow of the three soils increased by 1.00~1.49 times with the increase of flow intensities and 0.99~1.29 times with the increase of slope. (2) The interaction among flow intensities, slope and fractal dimension of soil particles had the greatest influence on the average runoff yield on slope, while flow intensity had the greatest influence on runoff. The runoff rate and runoff yield of the three soils increased with the increase of flow intensities by 1.09~6.10 and 1.05~5.74 times respectively, and increased with the increase of slope by 0.80~2.59 and 0.82~2.59 times respectively. (3) The interaction between the intensities of flow and slope had the greatest influence on the sediment yield and sediment yield. The sediment rate and sediment yield of three soils increased with the increase of flow intensities, increased by 1.17~5.67 and 1.17~5.20 times respectively, and increased by 0.96~3.32 and 0.94~7.54 times respectively with the increase of slope gradients. These research results could provide a theoretical reference for soil erosion prediction and loss control of engineering accumulation slope with different soil properties.
