摘　　要：在分析勘察区水文地质条件的基础上,用水量均衡法计算了该区地下水的补给量和排泄量,结果为负均衡。水源地开采后水源主要来源于黄河激发补给量,抽水试验和数值模拟表明黄河激发补给量为3.45×104m3/d。根据水位预测,水源地开采20年后和不利水文、气象条件下连续开采2年,水位下降值均不及含水层厚度的1/10,说明水源地开采量3×104m3/d是有保证的,可以满足电厂供水要求。Based on the analsis of the hydrogeological conditions of the survey region, the groundwater recharge and discharge quantity is calculated with water balance method. The result of calculation is negative balance. After groundwater mining, the water source being mainly from the increased recharge of the Yellow River. The pumping test and the numerical simulation show that the increased recharge of the Yellow River is 3.45 × 10^4m^3/d. According to water level forecast, after the water source being developed for 20 years or for 2 years running under adverse hydrological and meteorological conditions, the lowering of both water level is less than one-tenth of the aquifer thickness. This indicates that a mining rate of 3 × 10^4m^3/d is assured which can satisfy the water supply demand of the thermoelectric plant.
