| 英文摘要 | The special geographic characteristics coupled with unreasonable tillage activity and coexistent multiple erosive forces (rainfall, snowmelt, and wind) induce severe soil erosion in the Mollisol region of Northeast China. However, the studies on long slope erosion-deposition patterns under different tillage systems driven by multiple erosion forces are rare. Therefore, this study was to identify the effects of flat tillage (non-ridge tillage, FT), longitudinal wide-ridge tillage (LWT), and traditional longitudinal ridge tillage (LRT) practices on the spatial patterns of long slope erosion-deposition and sediment transport along the three natural long slopes with 320 m slope length by using Rare Earth Elements (REE) tracing method during the rainfall, snowmelt and wind erosion periods. Soil erosion rates driven by rainfall, snowmelt and wind were 1678.5-2558.5 t km-2 a-1 for the FT, 1089.0-1468.9 t km-2 a-1 for the LWT and 181.9-314.4 t km-2 a-1 for the LRT, respectively, in which the sediment yield with the FT, LWT and LRF driven by rainfall and snowmelt accounted for 88.0 %-96.4 % of the total sediment yield. During the rainfall erosion period, the erosion regime was dominated on the slopes with these three tillage practices, whereas deposition only occurred at the slope toe. For the FT, 73.6 % of the sediment mass was deposited at the 0-120 m slope length. A total of 50.7 % of the sediment was deposited at the 0-80 m slope length with the furrows of LWT, whereas all the sediment was transported out of the entire slope with the furrows of LRT practice. During the snowmelt erosion period, a spatial pattern with erosion-deposition alternations was observed for the FT and LWT, whereas the erosion regime dominated on the slope with the LRT practice. During the wind erosion period, there were evident periodical changes with strong-weak alternations for all three tillage practices. The findings of this study served as a scientific reference for implementing precise soil conservation measures for controlling compound soil erosion in the Chinese Mollisol region. |
