摘　　要：为了对内蒙古巴彦浩特水源地地下水资源状况进行评价,对水源地的地下水资源总量、可开采量及水质进行了计算和分析。结果表明:利用水均衡法计算得到巴彦浩特地下水总补给量为687.573万m3/a,总排泄量为728.673万m3/a,总补给量与总排泄量的差值为41.100万m3/a,占总排泄量的5.98%,计算结果与实际比较符合;采用开采系数法、抽水试验法、水位恢复法计算得出地下水可开采量分别为541.858万、596.758万、621.234万m3/a,选取最小值作为水源地可开采量;开采井的水混合后的水质分析表明,氯化物含量超标,供水过程中应对氯化物进行处理。In order to evaluate the groundwater resources of Bayanhaot water source area of Inner Mongolia,the total quantity,production and qual-ity of groundwater resources of water source area were calculated and analyzed. The results show that the Bayanhaot groundwater recharge is 6. 87573 million m^3/a,total discharging is 7. 28673 million m^3/a,the difference of total recharge and total discharging is 411,000 m^3/a,accounting for 5. 98% of the total discharging and the calculation results are in good agreement with the actual;using mining coefficient method and pumping test method and the water level recovery method,it obtains that the available exploitation of groundwater is 5. 41858 million,5. 96758 million and 6. 21234 million m^3/a respectively,selecting the minimum value as the available exploitation of water source area. The mixed mining wells of water after the water quality analysis shows that the chloride content is exceeded,it should treat the chloride during the process of water supply.
