The water plant are one of the cores of constructed wetland. 9 kinds of typical water plants have been chosen as the research object. The purification effects of water plants on the experimental model of northern rivers are investigated. The results show that all of the plants in constructed wetland have pretty good purification effects. The order of purifying capabilities are summarized as follows:submerged plants >floating plants >emergent aquatic plants.
