摘　　要：在分析瓯江河口潮流泥沙特性基础上 ,认为瓯江口挟沙能力与水动力及泥沙等因素密切相关。采用断面垂线平均的处理方法 ,引入背景含沙量的概念 ,线性回归拟合出瓯江口挟沙能力公式 。On the basis of the analysis of the tidal current and sediment character of Oujiang Estuary, the sediment carrying capacity is related to its hydrodynamic factors and sediment factors. By using of average values of several observed lines in the same cross-section togethere with the introduction of the concept of background sediment concentration, a linear regression formula of sediment carrying capacity in Oujiang Estuary has been obtained. Thus an accessorial equation for the calculation of 2-D tidal current and sediment mathematical model is provided.
