摘　　要：大气降水入渗系数α、地下水径流模数M是最基础的水文地质参数,文章以封闭型寨底岩溶地下河流域结合2013年3月至2014年2月一个完整水文年的水位、流量、雨量高频率监测数据,采用水量均衡法得到了岩溶区枯平丰水期大气降水入渗系数,分别为0.352、0.528、0.726,平均入渗系数为0.635。地下水径流模数分别为8.32、19.80、61.15L·s^(-1)·km^(-2),年平均径流模数为33.36L·s^(-1)·km^(-2)。其计算方法和计算结果对同类型岩溶区水资源评价等有一定的借鉴意义。The precipitation infiltration coefficientαand groundwater runoff modulus M are the most basic hydrogeological parameters.In this paper,based on the high frequency monitoring data of water level,flow,precipitation of Zhaidi karst underground river basin in a hydrological year from March 2013 to February2014,the precipitation infiltration coefficients for dry season,normal season and rainy season have been computed by means of water balance method,which are 0.352,0.528,0.726,respectively,and the average infiltration coefficient is 0.635.The groundwater runoff modulus are 8.32,19.80,61.15L·s^（-1）·km^（-2）,respectively for the above three seasons,and the average annual runoff modulus is about 33.36L·s^（-1）·km^（-2）.The calculation method and values of precipitation infiltration coefficient and groundwater runoff modulus have certain reference significance in water resources evaluation for the same karst area.
