摘要

通过人工模拟降雨试验研究了谷子地不同留茬高度及不同坡度的水土保持效应。结果表明，15cm留茬高度相对于未留茬处理径流量减少了18.6%，留茬5cm与10cm无显著减少径流作用;留茬能够减小产沙量14.36%∼19.47%;5，10，及15cm留茬高度对产流时间没有显著影响，坡度的变化对产流时间无显著影响;坡度为10°时，径流对土壤的侵蚀最明显;留茬高度为15cm的处理水土保持效应最佳。

Abstract

The effects of stubble application and slope gradient on soil and water loss are studied. The 15 cm stubble mulch application can reduce runoff amount by 18.6>.Stubble application can reduce sediment yield by 14.36>-19.47>.Crop stubble application with a height of 5

10，and 15 cm and slope gradient has no significant effects on initial runoff time. The 150 slope steepness has a significant effect on soil erosion. The 15 cm stubble mulch application has the most significant effect on soil and water conservation.
