摘　　要：采用Visual-MODFLOW软件中SEAWAT模块建立变密度地下水流与溶质运移数值模型,对青岛大沽河地下水库南端残留咸水运移情况进行模拟。采用2001-2002年的降雨、蒸发、开采等资料,识别和验证模型,并在现有的开采条件下模拟研究区地下咸水未来10年的运移情况进行预测。研究发现,研究区内地下咸水总面积略有减小,靠近大沽河一侧咸水浓度降低,而魏家屯附近咸水浓度升高。A variable density groundwater flow and solute transport numerical model is established using SEAWAT, a module of Visual--MODFLOW, to simulate the migration of residual salt water in on the southern tip of the Dagu River underground reservoir in QingDao. The data such as rainfall, evaporation and groundwater exploitation in 2001 to 2002 is used to identify and validate the model, and the migration of the underground saline water in the study area in the next 10 years is predicted with the current mining, conditions. Through the simulation, it found that the total saline water area of the study area decreases slightly, the concentration of salt water is close to the side of the Dagu River reduces and the concentration of salt water in WeiJiatun is too much.
