摘要
文章提出利用水量平衡原理,结合降雨—径流—侵蚀经验模型来定量地评价单次暴雨小流域产流产沙分布规律;并以陕北黄土高原纸坊沟小流域1989年7月16日暴雨为例进行了实例分析与计算。结果,计算所得到的小流域产流量和产沙量值与实测值相差只有1.1％和4.4％,说明方法合理。
Using water balance principle and combining with experience model of rainfall-runoff-erosion, this paper quantitativly evaluated the distribution laws of runoff and sediment generation in small watershed under a single storm, and made analysis and calculation with the storm data in Zhifanggou small watershed on the Loess Plateau on july 16,1989 as an example. Difference between calculated value and observed value of runoff and sediment generation is 1.1%and 4.4％ respectively. The results showed that this method is reasonable.
