Abstract In the wetland system，woody plants generally have more biomass and longer life than herbs，and have stronger bioaccumulation ability than organic matter，nitrogen and phosphorus． If the woodyplants could be adapted to the water environment could be applied to the constructed wetland，and thelayered plant communities are constructed，the complicated maintenance work in the later stage of theconstructed wetland could be avoided and the cost of wetland management will be reduced． It could alsoovercome the niche vacancy caused by the seasonal blight of the traditional constructed wetland，maintainthe effect of sewage treatment，and ensure the durability of the operation of the constructed wetland． Thisaccords with the construction idea of low maintenance and durable constructed wetland，and it was worthpopularizing in the constructed wetland configuration． The research of woody plants in constructed wet-land is reviewed，and the prospect of application of woody plants in constructed wetland was prospected．
