摘　　要：研究在降雨条件下的地面积水,积水深度的大小对于下垫面的下渗速度影响,确定平原区地面积水与雨强变化的关系。结果表明,地面积水过程分为径流积水和滞留积水,稳定产流阶段的地面积水随雨强呈良好的线性关系;对于雨强一定,不同介质的平原区,地面积水与历时呈直线或曲线关系。对山西省水文计算和水资源评价工作具有重要的现实意义。The influence of the depth of seeper in plain on seeping rate of underlying surface is studied,and the relation between seeper in plain and rainfall intensity is determined. The results show that the seeper has two parts of runeff seeper and detention seeper;the seeper is linear with rainfall intensity;when the rainfall intensity is steady, the seeper in plain is linear or curve with time according to different mediums of plain.

关 键 词：断面径流量 径流积水深度 滞留积水深度
