With the development of the national economy, Xintai City, being poorer in industry, has now become a middle-developed one, which is characterized by mechanical, coal and energy industry, and the need for ground-water resources is increasing daily. Thus it is urgent to deal with the calculation and evaluation of the limestone karst in Ordovician strata of this region. In the course of the calculation of the ground-water resources in the Ordovician limestone karst, Baiquan region, we used three methods, namely the synthetic infiltration coefficient method, the statistic actual grainge, and the undergrour, d runoff coefficient. The results calculated by means of these three methods were approach. The average data of them may be used as the ground-water winning resources in the Ordovician limestone karst in this region, and 10.6666 M~3/S as the average winning resources of years. On the basis of the analysis of the regional geology and the hydrogeological condition togather with more consideration of the ground. water moving character and of the measurement data of the river infiltration flow, we calculated the recharge volume in the last twenty years.
