摘　　要：地下水流系统理论是当代水文地质学的核心概念框架,为了使学生深入掌握地下水流系统理论知识,培养学生实践创新能力,设计和制作了河间地块潜水含水层、承压含水层、多源汇的潜水盆地等砂箱实验装置,学生通过砂箱实验能直接观察地下水流系统的多级次嵌套特征,研究不同水文、气象、非均质结构和人类开采活动等因素对地下水流系统发育模式的影响,可掌握系统发育模式演变的物理实质。实验教学中,通过问题提出、自主预习、分组讨论、砂箱实验、提交报告、汇报总结6个教学环节的连贯实施,促进了学生做、学、研相结合。The theory of groundwater flow system is the core conceptual framework of modern hydrogeology.In order to help students to apply groundwater flow system theory and cultivate students’practical and innovative ability,the sandbox experiments are developed and applied in the postgraduate course teaching,and the experimental teaching methods are discussed.Three kinds of sandboxes are designed including the phreatic aquifer between two rivers,the confined aquifer and the phreatic basin with multiple sources and sinks.Students can design and carry out experiments by themselves,to model the hierarchically nested groundwater flow system,study the influence of hydrology,meteorology,heterogeneous aquifer and human pumping activities on the groundwater flow system pattern,and finally grasp the physical essence of system pattern evolution.Through the implementation of six sequential teaching links,such as problem posing,self-preparation,group discussion,sandbox experiment,report submit,presentation and summarization,students can combinate the process of doing,learning and researching.
