摘　　要：植物是水生态功能系统中必不可少的因素,是水生态系统中重要的生态因子。目前,大多学者在水流阻力、流动结构等方面对刚性植物做了大量研究,有较丰富的成果,但不同柔韧度的植物对通过其的水流存在较大差异,还没有文章比较全面的总结柔性植物对水流特性的影响,从水流阻力、流动结构及紊动特性等方面回顾总结了当前含柔性植物水流问题研究的主要成果,探讨了当前含柔性植物水生态功能系统尚未解决的问题,并指出了今后的研究趋势。Plants are essential factors of the ecological function of the water system,and are the most important elements of the aquatic ecological system.Most scholars have done a lot of research on rigid plants,the rich results include additional effect of rigid vegetation on the water flow,the structure of flow due to the plants.But there is a great difference in different pliability plants through its flow.No paper is a comprehensive summary of flexible plants＇impact on the flow characteristics.This paper reviews and sums up the main results from the previous researches on the effect of flexible vegetation on water flow.Unsolved problems are also discussed.and the future research trends are highlighted too.

关 键 词：阻力 流动结构 紊动特性 柔性植物
