Planting reeds is an important way to protect and recover lake wetland, research on birds is helpful to evaluate the recovery efficiency of the wetland ecological function. From June 2010 to May 2011, we conducted a survey on bird community structures in the Suzhou Taihu lake national wetland park. Our results indicated that: fifty bird species which belongs to 11 orders, 28 families were recorded, and there were 39 species of birds in the planted reed wetland and 36 in the original reed wetland respectively, from which 25 species were recorded in both habitats. Resident birds such as Paradoxornis webbianus, Gallinula chloropus, Pycnonotus sinensis and Prinia inornata had always been dominant position in the two wetlands. In general, the change trend of bird species and density were more consistent, the lowest respective in January(11species) and February(25.86pcs/hm₂), reached maximum in May(30species)and June(73.64 pcs/hm₂). Looked from each season, the biodiversity of planted reed wetland was abundant in spring (H′=3.4115) and summer (H′=3.0501), while the evenness index of planted reed wetland was under planted reed wetland in spring(J=0.9935), summer(J=1.0359) and autumn (J=0.8315).All over a year, the diversity and evenness index of planted reed wetland(H′=3.2747, J=0.8939) were under original reed wetland(H′=3.3002, J=0.9209). From the view of the birds community of the two reed wetland, no significant difference were observed in each data, the planted reed wetland restoration was close to original reed wetland.
