【摘要】 文章综述了生态湿地的应用动态、工艺复合方法及其数值模拟研究进展。近年来，复合型湿地工艺（如水平-垂直潜流湿地、自由水面型湿地和梯级生态湿地）逐渐兴起，通过优化组合不同湿地类型，显著提升了污染物去除效率。数值模拟方法在湿地研究中日益重要，有助于解析湿地净化机理，指导湿地流场优化，提升水质净化效益，为实际工程设计提供技术支撑。更多还原

【Abstract】 The article summarizes the application dynamics, process composite methods, and numerical simulation research progress of ecological wetlands. In recent years, composite wetland processes(such as horizontal vertical subsurface flow wetlands, free surface wetlands, and cascade ecological wetlands)have gradually emerged. By optimizing the combination of different wetland types, the pollutant removal efficiency has been significantly improved. Numerical simulation methods have become increasingly important in wetland research, helping to analyze the purification mechanism of wetlands, guide the optimization of wetland flow fields, enhance water purification benefits, and provide technical support for actual engineering design.更多还原
