[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.
