摘　　要：根据咸阳市区地下水开发利用存在的问题,以咸阳市区为研究对象,建立了研究区水文地质概念模型和三维地下水数学模型,模拟了不同气候情景下地下水位的变化趋势。预测研究表明,未来降水量增多气候情景下,地下水位上升,地下水位变化与气候因素的关系密切;开采量的减量幅度较大时,地下水的恢复效果更加明显。人类长期不断增长的地下水开采,是导致区域地下水位持续下降的主要原因。通过开源节流等措施,是恢复地下水环境的有效途径。Based on the problems in groundwater development and utilization in the urban area of Xianyang, a conceptual model of hydrogeology and a three-dimensional mathematical model of groundwater flow are developed and the variation trend in groundwater levels under different climate scenarios is simulated. The results of prediction show that the groundwater levels will rise and are related closely to the climatic factors under the future increasing rainfall climate scenarios. Groundwater recovery effect is more obvious when the extraction reduces greatly. The main reason for the continual decline in regional groundwater levels is the long- term increase in groundwater exploitation by human being. Broaden sources of income and reduction in expenditureare effective ways to restore the groundwater environment
