中文摘要：

随着当前河道水体微污染特征日益明显，生态浮床技术越来越多地被利用来改善河道水质和维护河道生态环境。综合目前生态浮床研究现状，论述了近年来国内外生态浮床植物的净化机理以及生态浮床布设对水体净化效果和水动力特性影响的研究进展。针对当前生态浮床研究中存在的不足，指出应加强生态浮床水动力特性研究，不仅能够完善生态浮床修复过程的净化机理。也是为生态浮床在城市河道中布设提供一定的理论参考和设计依据。

英文摘要：

Because of the increasing obvious characteristics of river water micro-pollution, the ecological floating bed technology was applied to improve river water quality and maintain the river ecological environment more extensively at home and abroad. Based on the current research on sloping lands, a discussion was made on the purification mechanism of plants and water purification effect and hydrodynamic characteristics affecting of ecological floating bed.In consideration of some inadequacies in current research, it is pointed out that the study of hydrodynamic force characteristics of ecological floating bed can provide the process of purification mechanism r and the theory reference and design basis of ecological floating beds.
