摘要
黄旗海平原区是集宁市主要供水水源区,地下水为第四纪松散孔隙潜水,含水层厚度大、水量丰富、补给充足、水质较好。根据数值模型计算的结果,全区地下水多年平均补给资源量为6795.82×104m3/a,大气降水入渗量占总补给量的78%;现状开采量为1446.66×104m3/a,有较大的开采潜力,可新增开采量2463.75×104m3/a。在幸福村和薛家村两处适宜兴建水源地,日供水能力分别为4.35×104m3和2.40×104m3。文中同时还提出了集宁市地下水可持续利用对策。
Hangqihai plain is main water supply headwaters area in Jining, groundwater is quaternary relax phreatic water, thickness of aquifer is bigger, the quantity is abundant and supplies ample of groundwater, water quality is better. According to the calculating result of digital model, the quantity of groundwater supplies is 6795.82×104m3/a, the quantity of atmosphere precipitation soak declines have 78% of the total replenishment quantity; The quantity of exploitation nowadays is 1446.66×104m3/a, the potential of development is bigger, incremental allowable exploitation quantity is 2463.75×104m3/a.Two place is feasible for building waterhead at Xingfucun and Xuejiacun, the exploitation quantity is 4.35×104m3/d and 2.40×104m3/d. At the same time,the author presented countermeasure of groundwater resources sustainable development.
