河床质中几乎没有悬移质颗粒，对河床演变起主要作用的是推移质泥沙。 - In this paper , gravel characteristics and variety along the river were studied with digital image technology ; variety of grain sizes distribution of the river bed along jinmahe section in minjian river was analyzed ; several representative formulas of bedload transport rate were proved according to the field data of dujiangyan
本文采用数字图象技术研究了卵石颗粒的几何特征及沿程变化；分析了岷江金马河河段河床质级配的沿程变化；根据都江堰的输沙率资料论证了几家有代表性的推移质输沙率公式的实用性。 - Based on the topographic features and data of sediment particle size of bed load at the fluctuating backwater reach of liujiaxia reservoir , the streamwise variation and variation process of median diameter of bed load during silting and scouring periods of the fluctuating backwater reach are analyzed , and it can be seen that the turning point for the sediment diameter variation from coarse to fine is located at the outlet of shigou gorge of the fluctuating backwater reach
摘要根据刘家峡水库变动回水区的河段地形特征和历年河床质泥沙粒径级配资料，分析了变动回水区河段淤积和冲刷时，河床质泥沙中值粒径的沿程变化和历年河床质泥沙中值粒径变化过程，并指出粒径分布由粗变细的转折点在变动回水区寺沟峡峡口处。
