含植物河道水动力特性研究进展

Advances of study on hydrodynamic characteristics of vegetated channel

水生植物群落是河流生态系统的重要组成部分,利用天然植被护坡固土、净化水质、改善河流生态环境已成为河流生态修复的重要措施。本文从水生植物影响下的河道水流阻力特性及水流结构两方面,总结了国内外对含植物河道水动力特性的研究进展,并对该领域的未来研究方向提出了展望。

Aquatic vegetation community is an important part of the river ecosystem,and then improving the river ecosystem by means of slope protection,soil fixation and water purification with natural vegetation becomes an important measure for river ecorestoration. From the aspects of the river flow resistance characteristics and the flow structure under the impact from aquatic vegetation,the advances of the study made on the hydrodynamic characteristics of river channel at home and abroad are summarized herein,while the future study trend of this field is prospected as well.
