Hydrodynamic characteristic is an important reference for ecological revetment engineering to select vegetation material. From the hydrodynamic characteristics of navigation junction, the paper divided embankment into bottom-protection zone, key-protection zone, hydrophilic zone, landscape zone according to different water levels of hydrodynamic characteristics. Combined with ecological characteristics of plants (flood and erosion resistance are main factors), it selected different types of plant and allocation models that were suitable for different protection areas. Taking Guangxi Naji demonstration engineering of ecological revetment for example, The paper probed into the vegetation selection in different protection zones.
