摘　　要：水系连通是水体水质保持与改善的途径之一,为此,基于二维有限元数值模拟方法分析了水系连通方案的效果。以天津滨海新区东丽湖、北塘水库以及黄港一库、二库为例,首先,根据研究对象特点,设计并建立了三角形网格的二维水体水动力数学模型;其次,应用SMS软件对研究区域水体水动力及水质状况进行了试验性模拟;最后,基于上述模拟结果,分析并确定了研究区域水体的优化连通方案。二维有限元分析和SMS软件能够直观、准确地模拟水体水质变化,并具有较强的实用性,能够为工程改造提供决策依据。Water connectivity is one way to keep and improve water quality. Therefore, the effects of water connectivity solutions were analyzed based on two-dimensional finite element. Taking Dongli Lake, the first and second Huanggang reservoirs and Beitang reservoir in Tianjin Binhai New Area for ex- amples, two-dimensional hydrodynamic models with triangular mesh were designed and buih according to the regional characteristics. Surface water modeling system （SMS） was applied to simulate hydrodynamic and water quality of the regions. The optimal water connectivity solutions were established based on the simulation results. The results showed that two-dimensional finite element analysis and SMS could simu- late water quality effectively and practically.
