摘　　要：阐述环境流体动力学模型(EFDC)的基本原理,结合苏州市吴江区三白荡的具体情况建立水流模型,讨论模型参数的设计、预测方案的选取,并对模拟结果做出具体的分析。分析结果显示,模型对三白荡的水流模拟具有较强的实用性,与实物资料吻合较好,不仅反映了湖泊的水流联系情况,而且显示了湖泊岸线受风浪侵蚀、出入湖水量分配情况。模型为湖泊岸线设计、环境容量研究、陆地污染物排放控制提供较强的技术支撑。此外,模拟结果对研究太湖流域类似三白荡的浅水湖泊水动力过程具有较强的借鉴意义。The basic principle of environmental fluid dynamics model(EFDC)was expounded,and the flow model was established according to the specific situation of Sanbai Lake in Wujiang District of Suzhou City.The design of model parameters and selection of prediction scheme were discussed,and the simulation results were analyzed in detail.The analysis results showed that the model had a strong practicability in simulating the water flow of Sanbai Lake,and was in good agreement with the physical data,which not only reflected the connection of the water flow of the lake,but also showed the distribution of the water flow in and out of the lake under the erosion of the shoreline by the wind and waves.The model provides strong technical support for lake shoreline design,environmental capacity research and land pollutant emission control.In addition,the simulation results have strong reference significance for the study of hydrodynamic process of shallow lakes similar to Sanbai Lake in Taihu Basin.
