摘要
系统归纳了描述潜流带氮素迁移转化行为的水动力、溶质运移、微生物生长数学模型及其耦合关系,分析了耦合模型的主要参数及其影响因素,探讨了试验数据获取、过程耦合关系建立、模型参数识别对数值模拟不确定性的影响。针对现有研究的不足,提出了未来应加强潜流带原生环境监测、热传输过程与其他过程耦合、多维度多过程耦合模型优化计算等方面的研究。
This paper systematically summaries the mathematical models of hydrodynamics,solute transport and microbial growth processes,which describe nitrogen transport and transformation behavior in the hyporheic zone,as well as the coupling relationships of these models.The main parameters and influencing factors of the coupled models are analyzed.The influence of experimental data acquisition,process coupling relationship establishment and model parameter identification on the uncertainty of numerical simulation is discussed.In view of the shortcomings of the existing research,it is proposed that more research should be devoted to the original environment monitoring of the hyporheic zone,the coupling of heat transfer process with other processes and the optimization calculation of the multi-dimensional multi-process coupled model in the future.
