摘要
太湖水体浊度是浮游植物接受光照强度的重要影响因子,而浊度主要受到悬浮泥沙浓度的影响.综合风生流及波浪两方面的因素,采用三维风生流泥沙输运模型对太湖泥沙输运进行了数值模拟研究.将模型模拟结果与实测太湖风生环流及太湖含沙量资料进行了对比分析.验证结果表明,三维风生流泥沙模型基本反映了太湖风生环流及泥沙输运的特点,能为太湖水生态系统模拟提供技术基础.
The turbidity in Taihu Lake is an important factor to the light intensity for phytoplankton,and it is mainly affected by the concentration of suspended sediment.From the two factors of wind-driven flows and waves,a 3D wind-driven and sediment transport numerical model was adopted to simulate the cohesive sediment transport in Taihu Lake.The simulated results were compared with the observed data of wind-driven flows and sediment concentration.The validation results show that the proposed model essentially reflects the characteristics of the wind-driven flows and sediment transport in Taihu Lake,and it can provide a technical basis for the simulation of aquatic ecosystem in Taihu Lake.
