摘要： Slope erosion in the black soil region of Northeast China is complex and specific. In order to effectively control soil erosion and protect scarce black soil resources, it is necessary to reveal the law of soil erosion and the influence of basic units of soil structure on its erosion process. This paper used three treatments in the Le Bissonnais (LB) method to determine soil aggregate stability parameters and soil erodibility K values based on particle size composition. By establishing a mathematical fitting of the slope erosion rate along the slope length, it is found that the sinusoidal function fitting can better characterize the periodic law of the slope erosion rate of the long and gentle slope cultivated land in the typical black soil region. The research shows that the primary mechanism of black soil aggregate breakage is dissipation and mechanical disturbance, while the damage caused by clay expansion is the least.
