摘　　要：山区河流坡陡流急、泥沙级配宽、相对水深小、河床结构发育、水流流动在空间上变化剧烈,使得山区河流的水流阻力和推移质运动关系十分复杂。总结了山区河流阻力及推移质运动模拟方法的研究成果,对比分析了典型的山区河流阻力公式以及山区河流推移质模拟方法中遮蔽函数的研究成果。研究表明山区河流阻力及推移质运动的试验及理论研究均有了较大进展,但在体现边界非均匀性对水流特性的影响以及具有广泛适用性的阻力及推移质运动模型方面还需深入研究。Mountain streams feature steep slopes,torrents and shallow flow,wide grain size distribution,various developed river bed structures and sharply variations in the streamwise direction.Such flow complexities make resistance relations and bed load transport equations in mountain streams unclear.The paper summarizes advances in flow resistance and bed load transport in mountain streams.Typical flow resistance relations and hiding function in bed load transport equations are evaluated.Researches demonstrate that there is major progress in experimental and theoretical research on flow resistance and bed load transport in mountain streams.More efforts should be made on the impact of boundary non-uniformity on flow resistance and a widespread applied flow resistance and bed load transport model.
