Abstract: Abstract: Forested wetlands are rare in China because most of them have been destroyed by the long history of human disturbances. Consequently, reconstruction and restoration of freshwater forested wetlands lack reference sites for community composition. We investigated tree species to lerance to water logging for a wetland restoration project at the Shengjin Lake Nature Reserve of Anhui Province. A total of 15 woody species were tested in the annual flooding of low lakeshore areas. The survival rate of the seedlings was examined after 14 months since the woody species were planted. The inundation survival rate was 98.9%, 98.3%, 91.3%, 51.2%, 50.0%, 7.3%, 4.0%, 1.8% for native species ( Liquidamba formosa, Salix babylonica, Salix×aureopendula,Taxodium ascendens×T.mucronatum, Sapium sebiferum, Metasequoia glyptostroboides, Alnus trabeculosa, and Pterocarya stenoptera ), respectively, and 79.7%, 72.4%, 56.8%, 55.7%, 34.6%,15.8%, 6.3% for the exotic species (Populus deltoie, Taxodium ascendens, Salix integra, Diospyros kaki, Taxodium distichum, Carya illinoensis, and Nyssa aquatica ), respectively. The inundation survival rate was 100%, 100%, 100% and 95.2% for the species of Salix babylonica, Liquidamba formosana, Populus deltoe and Taxodium ascendens under flooding for 60～90 d with a average 81.7 cm depth water, 97.7% and 93.8% for Salix×aureo-pendula and Taxodiam ascendensx×T.mucronctum under flooding for 60～90 d with 65.9 cm depth water. Six suitable species were selected, they are Salix×babylonica, Liquidamba formosana, Salix aureo-pendula, Taxodium ascendens, Populux deltoids, Taxodium distichum and Taxodium ascendens×T.mucronatum for the vegetation restoration and reconstruction of the forested freshwater wetland in Shengjin Lake Nature Reserve.
