Abstract:: To quantify the impact of rainfall intensity and slope gradient on characteristics of aggregate losses, black soil slope surface soil(0—10 cm)was selected as the research object, the research method of the simulated rainfall was adopted to compare the aggregate loss characteristics, and calculate the contributions of rainfall intensity and slope gradient to the aggregate loss under different rainfall intensits(78, 127 mm/h)and the slope gradients(2°, 4°, 6°). The results showed that:(1)under the same rainfall intensity, the total losses of aggregates increased by 0.70～1.42 times with the increase of slope gradient; under the same slope condition, the total losses of aggregates increased by 1.94 times and 2.41 times with the increase of rainfall intensity at the slope of 4° and 6°, respectively;(2)with the increase of rainfall intensity, MWD and D had no significant difference; with the increase of slope, the MWD of runoff aggregates decreased significantly, and the D value only increased significantly when the rainfall intensity was 78 mm/h;(3)with the increase of slope, losses of the 5～1 mm, 1～0.25 mm, 0.25～0.053 mm of aggregates presented the trend of increase at first and then decrease, loss of<0.053 mm aggregate increased significantly; with the increase of rainfall intensity, the loss of small aggregates increased, while the loss of large aggregates only increased significantly under the condition of high slope gradient;(4)rainfall intensity was the main influence factor on losses of the 1～0.25 mm, 0.25～0.053 mm, <0.053 mm aggregate, and the contribution rate was 27.42%～47.09%; slope was the main affecting factor on the loss of 5～1 mm aggregate, and the contribution rate was 45.59%. These results can provide the references for clarifying the evolution of the quality of black sloping farmland and preventing soil erosion during hydraulic erosion.
