摘　　要：从研究方法、明渠紊流拟序结构、泥沙运动与床面形态、拟序结构与泥沙运动和拟序结构与床面形态等方面，总结了近年来国内外有关研究进展．在展望了研究趋势后，提出今后应该进行更加精细的实验研究，加深对拟序结构与泥沙运动相互作用的理解．Progresses in the research on the coherent structure of turbulence in open channel flow and the interactions among coherent structures, sediments and bedforms have been made in recent years. The brief review is divided into research methods, coherent structures in open channel flow, sediment movement and bedforms, coherent structures and sediment movement, coherent structures and bedforms, and so on. The emphasis is placed on the prospects of further studies. More accurate tests are suggested to deeply and study the interaction and the feedback mechanism between coherent structures and sediment movement.
