| 摘 要： | 为有效防治坡耕地水土流失,持续利用坡耕地,于2007-2010年在黄土高原西部坡耕地上研究保护性耕作对水土流失的影响,重点探讨传统耕作与免耕秸秆覆盖2种耕作措施下春小麦、鹰嘴豆、马铃薯与紫花苜蓿间作的水土流失规律。结果表明:(1)各处理8月份的径流量分别占观测时段内总径流量的46.46%～51.29%,侵蚀量分别占观测时段内总侵蚀量的40.10%～61.22%。(2)降雨量与径流量、侵蚀量间呈现多元多项式关系。(3)2007-2010年不同种植模式下径流总量和侵蚀总量的变化趋势是一致的,均表现出NTSPL |

| Abstract: | In order to reduce soil and water loss in sloping fields and sustainable utilization on fragile slopes,the field experiment was carried out to investigate the effects of conservation tillage on soil and water erosion in western Loess Plateau sloping fields in 2007-2010,and the effects of conventional tillage and no-tillage with stubble retention on soil and water erosion of spring wheat,chickpea,potato and lucerne in sloping fields was analyzed.The results indicated that:(1)The runoff in August accounted for 46.46%～51.29%,and the erosion amount accounted for 40.10%～61.22% of the entire observation time.(2)The relation among rainfall,runoff and erosion was multivariate polynomial.(3)Changes of the total runoff and erosion had the same trend in different planting patterns,which showed that NTSPL |
