Dynamic of plant community in rehabilitating wetlandA case study in Jinghe River Estuary

Jinghe river estuary wetland is one of the main proportion in wetland of Ebnur Lake. By using the method of space substituting time, vegetation was investigated in Wetland of Jinghe River Estuar at different restoration stages. The results indicated that Phragmites australis was the main dominant specie during the restoration process. After 1, 3 and 5 years of restoration, the number of species was 17, 11 and 1, community coverage was 85.98%, 96% and 100%; height of P. australis was 75, 85 and 234 cm, respectively. This implied that 4-5 year restoration could make the vegetation back to natural status if the water was enough.
