| 摘 要： | 潜水雨后地表径流由地表下潜水、雨水地面上径流、雨水风化层径流构成，三部分水均随河道流量的增减而增减。其中地表下潜水超过一半，雨水挤压和置换雨前地表下潜水的作用是该流域降雨形成产流的重要作用。雨水地面上径流在流量过程线退水段转折点附近基本消失。

| Abstract: | Stormflow consists of phreatic water, surface runoff and weather horizon-passing rain. The rise and drop of their discharge are consistent with that of the river discharge after rain. Phreatic water occupies more than half of the total discharge, and the squeeze and replacement of ancient water by new rain water are apparent during and after raining on the Qianshui river catchment area. The surface runoff nearly disappears near the C point on the drop section of the discharge curve. |
