摘　　要：水生植物是河流、湖泊、滨海湿地环境中不可缺少的一部分,植物的存在使水动力条件发生了改变,进而影响了泥沙悬浮和污染物的输运。从恒定流和波浪两种水动力条件出发,针对柔性植物影响下的水流阻力、水流结构、紊动特性、特征流速、消波系数、泥沙运动、污染物输运等方面,综述了国内外的主要成果,并指出复杂水动力条件下的植物-水流-泥沙-污染物之间的相互作用规律是今后研究的重点和难点。Aquatic plants are an indispensable part of the environment of rivers,lakes and coastal wetlands.The existence of plants changes the hydrodynamic conditions,thus affecting the suspension of sediment and the transport of pollutants.Starting from two hydrodynamic conditions of steady flow and wave,aiming at the flow resistance,flow structure,turbulent characteristics,characteristic velocity,wave attenuation coefficient,sediment movement and pollutant transport under the influence of flexible plants,the main domestic and foreign literatures are reviewed.The interaction mechanisms of vegetation-flow-sediment-pollutant under complex hydrodynamic conditions are proposed as the research focus and difficulty in the future.
