摘　　要：建立了地下水水流与溶质的耦合模型,应用FEFLOW软件,对研究区的水位与水质进行了模拟预测。预测结果表明,区内大部分地区明化镇组含水层地下水Cl-质量浓度为50～120mg/L,馆陶组为20～50 mg/L。地下水开采15年后咸水界面明显向内陆运移,咸水区北部运移距离大,速度快;咸水区两侧运移距离小,速度慢。模拟预测结果可为后期制定研究区优化开采方案提供参考。Groundwater flow and solute coupling model was established by using FEFLOW software to predict the level and quality of the groundwater in the study area. The prediction results showed that Cl- concentration in the groundwater aquifer was 50 to 120 mg/L in Minghua Town, and 20 to 50 mg/L in most parts of Guantao. Salt water interface dramatically migrated inland after the exploitation of the groundwater for 15 years, the north of the salt water area had long migration distance and moved fast, the two sides of the salt water area had small distance and moved slowly. The results of simulation and forecast could provide reference for further optimum mining scheme in the study area.
