摘　　要：运用指数 -活塞模型 (EPM) ,将平凉大岔河隐伏岩溶水系统视为线性时不变系统 ,以环境同位素氚作为输入输出信号 。The covered karst water in Dacha valley is consider ed as an independent rectilinear system by the exponent\|piston model(EPM).The r esidence time of the underground karst water and other hydraulic parameters are calculated through the environmental tritium as the import signal and the export signal.

关 键 词：隐伏岩溶水 地下水 滞留时间 EPM法 储水系数 环境同位素
