摘　　要：人工湿地因其具有负荷率高、耐冲击负荷、处理效果可靠、占地面积小、美化环境等优点,正受到生态工程领域越来越广泛的关注和重视。在潜流人工湿地系统设计中,水力学因素直接关系到污染物的去除效果。通过系统梳理国内外对潜流人工湿地水力学的研究方法及进展,分析了潜流人工湿地水力学特征参数及其影响因素,重点探讨了湿地构造、基质、植物和运行方式等因素对水力学特征的影响及其优化途径,为完善潜流人工湿地系统水力设计,提高水力效率,提升污染物去除效果提供理论指导和技术支持。Subsurface flow constructed wetland （SSFW） is drawing more and more attentions in ecological engineering due to its high load rate, bearing capacity against impact load, reliable treatment effects, less occupied land, and aesthetic effect. In the de- sign of SSFW, hydraulic condition has significant and direct influences on the removal efficiency of pollutants. The research methods and progress on hydraulics of SSFW were illustrated in this paper. The characteristic parameters of hydraulics of SS FW and their impact factors were analyzed. The effects of construction, filter, plato-, and inflow configuration of SSFW on the characteristics of hydromechanics were discussed, which can provide theoretical and technical support on hydraulic design of SS FW,increasing of hydraulic efficiency,and improvement of removal effects on pollutants.
