Regarding the river management project，the defects and disadvantages of the traditional hard slope protection are analyzed，the advantages and characteristics of the plant-based ecological slope protection are expounded，and the mechanism of the plant-based ecological slope protection is discussed. Combined with the experience of domestic river control engineering，several common plant-based ecological slope protection technologies are systematically analyzed，and the technological characteristics and applicability of each technology are proposed. Relying on specific examples of river management projects，the advantages and disadvantages of different processes of plant-based ecological slope protection technology are evaluated from the perspectives of project cost，scour resistance，integrity，terrain adaptability，and applicable characteristics. The results show that：1）The plant-based ecological slope protection is a complete ecosystem，which is composed of water-soil-plant interaction. 2）Its effect mechanism includes hydrological effect and mechanical effect.3）At present，the plant-type ecological slope protection technology is widely used in the river regulation engineering in China，and its application range and application characteristics are different.4）For the river regulation and ecological restoration of a secondary tributary in the Songhuajiang river basin，the hollow hexagonal plant-type ecological slope protection and the gabion stone plant-type ecological slope protection materials are adopted，which have strong applicability and popularization.
