摘要
分三个方面介绍了河口最大浑浊带研究中数学模拟研究的进展：（１）利用通量分析计算河口盐度、污染物和泥沙通量，分析带内泥沙富采机制；（２）由物质平衡原理建立一维和较简单的机理模型，讨论最大浑浊带的成因；（３）据水动力方程和物质平衡方程建立二维或三维数值模型，计算最大浑浊带的水流结构和物质浓度分布，模拟并探讨不同条件下最大浑浊带的成因和演化机制。
In this paper,the advances of mathematical modeling of turbidity maximum in estuar-ies are introduced in three aspects:①To calculate salinity,contaminant and sediment con-centration with flux analysis method to study the mechanism of sediment amassing in estu-aries.②To establish one dimensional model or some simple model with mass balancingprinciple to explain the formation of turbidity maximum,③To establish two or three di-mensional numerical model with momentum and continuous equations to calculate the dy-namical feature and the distribution of mass concentration in estuary. Then analyse theformation and development laws of turbidity maximum under various assumptions.
