摘要

摘要: 利用二维水体和物质长期输运速度及其机制分解形式,分析了长江口1997年洪季观测资料,从实践上认识悬沙、盐度和水体长期输运的分离程度.观测站资料的计算分析表明:最大浑浊带附近,二维悬沙和水体长期输运速度平均夹角为36.0°、速度量值平均相差29.9%,悬沙和水体长期输运具有明显的分离特征;盐度锋面附近,二维盐度和水体长期输运速度的平均夹角为43.6°、速度大小平均相差27.8%,盐度和水体长期输运具有明显的分离特征.

Abstract: With 2-D water and substance's long-term transport velocities and their decomposed items,the observation data is analyzed on 1997 flood season in the Changjiang Estuary to give the separation character of suspended sediment,salinity and water's long-term transport.In the turbidity maximum,the average value of the angle between 2-D suspended sediment's long-term transport velocity and 2-D water's longterm transport velocity is 36.0°,and the average discrepant value of their speeds is 29.9%,so there is obvious separation character of suspended sediment and water's long-term transport.In the salinity front,the average value of the angle between 2-D salinityps long-term transport velocity and 2-D water's longterm transport velocity is 43.6°,and the average discrepant value of their speeds is 27.8%,so there is also obvious separation character of salinity and water's long-term transport.
