摘　　要：地下水数值模拟是地下水资源评价的重要方法之一。应用GMS软件建立靖安水源地的地下水流数值模型,利用该模型对设计的不同开采方案进行模拟,预测降水保证率95%条件下各方案开采20年后的地下水流场变化及水位变化情况。结果表明,当水源地总开采量为10万m3/d时,地下水流场能够达到稳定状态,中心水位降深较小,不会对生态环境造成明显影响。The groundwater numerical simulation is one of the major methods for evaluation of groundwater resources. the groundwater numerical model of Jingan water source area is established by using GMS, and simulate different mining schemes designed with the model, forecasting the groundwater flow field and water level of various schemes in 20 years under the pre-cipitation guarantee rate 95%. The results show that when the total exploitation quantity of water source area is 100 000 m3/d, the groundwater flow field can reach a steady state, and the center water level drawdown is relative small, and which will not bring obvious influence on the ecological environment.
