摘　　要：基于图像处理技术,设计了含植物水流紊动及物质输运实验,通过学生自主开展实验方案设计、实验现场观察与实验结果分析,加强学生对河流动力学中河道水流紊动、泥沙起动及物质输运相关概念的理解,使学生熟练掌握相关理论知识、计算方法与监测技术。该实验教学对河流动力学课堂教学内容进行补充和拓展,并融合了科研中的前沿、交叉的科学问题,鼓励学生自主设计、独立分析,构建课堂教学-实验教学-科研反哺教学相辅相成的多元协同机制,有效提高了学生的实践能力和创新能力,增强了学生的科研兴趣,对人才培养模式改革和探索起到了一定的推动作用。Based on image processing technology,multi-scale turbulence flow experiment is designed and implemented in this paper.Through the observation and thinking,theoretical calculation and analysis,independent design and implementation process in the experiment of students are improved,concepts of flow structure and turbulence development are further understood,and the theoretical knowledge,calculation method and monitoring technology are mastered by students.This experimental teaching has supplemented and expanded the classroom teaching content.In addition,it integrates the advanced and interdisciplinary scientific issues in scientific research to encourage students to design and analyze independently.Based on this experiment,a multi-cooperative mechanism consisting of classroom teaching,experimental teaching,and scientific research is implemented,which could improve the engineering practice ability and innovation ability of students,enhance students'interest in scientific research,and promote the reform and exploration of talent cultivation.
