%X In order to understand growth of plant and its effect on ecological restoration of riparian zone, pilot-scale Scirpus yagara ohw. riparian zone had been studied for one year. Height and density of Scirpus yagara ohw in different water depth showed that the water depth endurance of Scirpus yagara ohw is not strong, and it grows and germinates better in shallow water. Contrast between harvest area and without harvest area showed that harvest is good for germination and growth of Scirpus yagara ohw in next year. Distribution of biomass and N and P fixation between the underground and overground Scirpus yagara ohw showed that N and P fixation of the underground is 50% and 126% more than that of the overground, respectively. Harvest of the overground Scirpus yagara ohw can remove 40.5% of the total N and 30.6% of the total P. Dunked in water for 130 days, the overground Scirpus yagara ohw lose 27.10% of its dry weight, 40.80% of the total N and 76.80% of tha total P. And the released pollutants have no serious cumulation in water.
