中文摘要	【目的】研究西北干旱区自然降雨与退化草地坡面产流产沙的关系,及坡面阻控措施对水沙变化的影响,为区域洪水防治和水土保持提供理论支持.【方法】基于2019年4~9月伊宁市北坡31场次降雨,分析降雨特征并制定侵蚀性降雨标准;在同一坡面设置枯草覆盖、水平沟、增渗孔以及对照等4种处理开展自然降雨径流监测实验,研究降雨特征与坡面产流产沙的关系,比较3种坡面阻控措施的效果.【结果】伊犁河谷次降雨最大30min雨强远大于平均雨强,具有明显的短时强降雨特征;当次降雨量超过4.0mm且最大30min雨强超过3.6mm/h时,可引发降雨侵蚀;坡面产流量与降雨量及前3d降雨量呈显著正相关,产沙量与降雨侵蚀力呈显著正相关;坡面处理措施对径流和泥沙削减效果均为:枯草覆盖>水平沟>增渗孔.【结论】伊犁河谷夏季短时强降雨是引发水土流失的重要条件,通过设置坡面阻控措施可降低短时强降雨对土壤的侵蚀,枯草覆盖和水平沟均能减少70%以上的产流产沙,有效减轻了坡面水土流失.
英文摘要	【Objective】In the arid area of Northwest China,the relationship between rainfall and erosion of degraded grassland and the influence of management measures on water erosion were studied,which provided theoretical reference for regional flooding prevention and soil and water conservation.【Method】Basedon 31rainfall events from April to September in 2019,rainfall characteristics have been analysed and erosive rainfall standard have been established.Four treatments were set on the same slope to carry out natural rainfall runoff monitoring experiments,including litter cover,level ditch,bore hole and control.The relationship between rainfall characteristics and runoff and sediment yield has been studied and the effects of 3kinds of slope management measures have been compared.【Result】The 30min maximum rainfall intensity of an single rainfall is much greater than the average rainfall intensity,showing an obvious short-term heavy rainfall characteristics.Rainfall erosion can occur when single rainfall exceeded 4.0mm and the 30min maximum rainfall intensity exceeded 3.6mm/h.Slope runoff are significantly correlated with rainfall and rainfalls of the previous three days.Sediment yield are significantly correlated with rainfall erosivity.The effects of slope treatment on runoff and sediment reductions are:litter cover>level ditch>bore hole.【Conclusion】The short-term heavy rainfall in summer is important for soil erosion,while setting slope control measures can effectively prevent slope soil erosion.Both litter cover and level ditch can reduce runoff and sediment yield by more than 70%.
