摘要
浅水湖泊也存在水动力垂向分层结构及污染物垂向非均匀分布情况,水力结构对水环境变化有重要影响,需要采用更加精细化的数学模型模拟其过程。针对国内外大型浅水湖泊三维水环境数值模拟相关研究及水动力参数取值方案进行了综述,对现有成果进行了总结与分析。指出下一步亟需构建复杂边界条件下的生态动力学模型,探索多条件耦合的富营养化微观响应机制,加强数值模拟精细化及参数规范化研究,为探索浅水湖泊水动力及水环境提供理论依据和技术支撑。
The vertical stratification structure of hydrodynamic force and the vertical non-uniform distribution of pollutants also exist in shallow lakes,and the hydraulic structure has important influence on the changes of water environment,so more refined mathematical models are needed to simulate the process.In this paper,the related research on three-dimensional water environment numerical simulation of large shallow lakes at home and abroad and the scheme of selecting hydrodynamic parameters were reviewed,and the existing achievements were summarized and analyzed.It is pointed out that the next step is to construct the ecological dynamics model under complex boundary conditions,explore the micro response mechanism of multi condition coupling eutrophication,and strengthen the research on numerical simulation refinement and parameter normalization,to provide theoretical basis and technical support for exploring the hydrodynamics and water environment of shallow lakes.
