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. |
