| 摘 要： | 在Rouse方程的基础上,结合统计学方法将泥沙质量浓度看作随机变量,选取自变量ln(h-z)/z,lnCa/ρx及lnu2/gd,采用多元线性回归方法分析各自变量对泥沙质量浓度垂向分布的影响,并检验它们对泥沙浓度垂向分布的影响程度.计算结果表明,该方法能够反映复杂动力条件下海安湾细颗粒泥沙质量浓度垂向分布的特征. |

| Abstract: | Based on the Rouse equation,the sediment concentration was regarded as the random variable,and the independent variables,lnh-z/z,lnca/ρs,and lnu2/gd,were selected using statistical methods.The multiple linear regression method was used to analyze the influence of the independent variables on the vertical distribution of sediment concentration,and the influence degree was tested.The calculated results show that the method can reflect the characteristics of the vertical distribution of fine granular sediment concentration in response to complex dynamic conditions in Hai’an Bay. |
| Keywords: | Rouse equation multiple linear regression Hai’an Bay estuarine and coastal sediment |
