摘　　要：随着临河区工农业和经济的发展,对水资源的需求增加,这将加大地下水资源的开采。对地下水水位预测,是为了避免发生地下水开采诱发的环境地质问题。在查明水文地质条件的基础上,应用地下水流数值模型分析了验证期水文年的水均衡,预测了近期和远期地下水水位。模拟期内,地下水系统总补给量为3.01×10^8 m^3/a,总排泄量为2.98×10^8 m^3/a,补排差0.03×10^8 m^3/a。预测结果表明临河区中心水位降落漏斗因压采方案的实施,略有回升的趋势。陕霸水源地和永胜水源地水位降落漏斗面积有不断向外扩展的趋势,且漏斗中心水位也呈持续下降趋势。The groundwater level prediction is intended to provide a basis on preventing environmental geological problems caused by excessive groundwater exploitation.Based on the identification of hydrogeological conditions,this study numerically investigates the groundwater flow model to analyze the water balance of the hydrological year in the verification period and predict the groundwater level in the near future and long-term basis.During the simulation period,the total-recharged volume of the groundwater system was 3.01×10^8 m^3/a,the total discharged water volume was 2.98×10^8 m^3/a,and the supplementary displacement was 0.03×10^8 m^3/a.The prediction results indicate that the water level landing funnel in the center of Linhe District will slightly rebound due to the implementation of the pressure mining scheme.The water level drop funnel area of the Shanba and the Yongsheng water source area will continue to expand outward,and the water level in the funnel center will continue to decline.
