[Objective] Cerasus humilis were unique economic fruit trees in China, its effects on soil physicochemical properties of slope field were studied to provide scientific basis for the extension and plantation in loess hilly area. [Methods] Relevant indexes of 5 fields with different standing conditions were measured before and after flood season. The effects of planting Cerasus humilis on soil fractal feature and soil erodibility on sloping cropland were analyzed by models of particle size distribution(PSD) and erosion-productivity impact calculator(EPIC). [Results] (1) During the flood season, planting had obviously buffer function against movement of soil clay particles on slop. Plantation in fish scale-like pit could effectively protect the slope surface soil; Plantation in level-terrace pit had significant effects on the interception and enrichment of soil fine particles in the middle and bottom of slope. (2) Soil fractal dimension was correlated negatively with soil sand particles with a coefficient of-0.611; while it had an significantly opposite correlation with clay particles, the correlation coefficient was 0.770. (3) By planting Cerasus humilis, the value of soil erodibility K could be reduced, correspondingly the anti-erosion ability could be improved. The effects on soil erodibility Kunder different land preparation methods of Cerasus humilis plantation had a rank as follows: level-terrace > scale-like > natural slope. (4) Negative correlations between soil erodibility K and the contents of organic matter and soil clay particles, their correlation coefficients were -0.957, -0.928, respectively. And positive correlations between K and soil bulk density, soil sand particles and soil silt particles, the correlation coefficients were 0.704, 0.667 and 0.512. [Conclusion] Planting Cerasus humilis had positive significance to control soil clay particles loss, to increase organic matter content, to optimize soil structure, and to improve anti-erosion ability.
