摘　　要：在贵州盘县架底金矿玄武岩分布区,选取一个典型小流域,通过观测小流域降雨过程中坡面产流的变化情况,推求小流域的降雨入渗系数,揭示小流域降雨入渗系数的变化规律,为架底金矿准确预测矿区涌水量提供技术依据。This paper selects a typical small watershed in basalt gold deposit area of Guizhou, Panxian Jiadi.The rainfall infiltration coefficient in small watershed was calculated by observing the change of nmoff yield during rainfall.Therefore the paper could reveal the rules of rainfall infiltration coefficient in small watershed and provide technical basis for accurate prediction of water inflow in mining area.
