根据流速垂线分布公式的结构不同，将流速垂线分布公式分为3类，并推导出3类流速公式对应的以垂线坐标为变量的含沙量垂线分布公式。理论研究表明，流速与含沙量的关系主要以流速梯度与含沙量梯度的关系为基础，基于该关系推导出与每类流速公式对应的以流速为变量的含沙量垂线分布公式，并分别讨论了3类流速分布对含沙量分布的影响，最终得到流速量级对含沙量量级的定量关系为指数倍的变化率。

According to the formula structure, the vertical distribution formulas of velocity are classified into 3 types. Then the vertical distribution formulas of sediment concentration corresponding to the 3 types of velocity formulas are deduced. The theoret-ical study result shows that the relationship between velocity and sediment concentration is close to the relationship between veloc-ity gradient and sediment concentration gradient, on this basis, the vertical distribution formula with velocity variable correspond-ing to each velocity formula is deduced. And the influence of 3 types of velocity distributions on sediment distribution is dis-cussed. It is concluded that the quantitative relation of velocity magnitude and sediment concentration magnitude is exponential one.
