摘　　要：为分析郑州航空港区应急水源地的持续开采能力,在合理概化研究区水文地质条件的基础上,建立了地下水流数值模型,并选择地下水模拟软件Processing Modflow进行了枯水年条件下三种开采方案的预测评价。结果表明,在机场以北面积约58.12 km2内,应急供水3.0万m3/d的开采量,只能满足0.5年要求。应急供水按1.8万m3/d开采,可满足开采5年的要求。在航空港规划区138km2范围内,开采量为1.5万m3/d,可满足开采20年的要求。研究结果为应急水源地运行提供了一定的依据。In order to analyze the continuous mining capacity of the emergency water source places of Zhengzhou Airport, based on the analysis of the hydrogeological conditions, the numerical model of groundwater system is established and the groundwater simulation software Processing Modflow is used to predict the three mining plans for the dry year conditions. The results show that, within about 58. 12km2 at the north airport the 30000m3/d of the emergency water supply only could meet the requirement for half year, and 18000m3/d could just meet the requirement for 5 years. Within the scope of the airport planning areas with 138km2 , 15000m3/d could meet the requirement of the mining for 20 years. The results could provide some basis for the running of the emergency water source places.
