From November 2008 to March 2009,the characteristic of the feeding habitat wintering Siberian Crane’(Grus leucogranus) was studied using line transect,plot sampling measurement and factor analysis methods in Poyang Lake National Nature Reserve of Jiangxi Province.We found: the distribution of the Siberian Crane in the Poyang Lake showed spatio-temporal dynamics,mainly affected by the factors of water and food.There isa significant selection of the Siberian Crane on the different feeding habitats(P < 0.05),and the bird favored on the habitat of submerged plants,dominated on Vallisneria atans,Hydrilla verticillata,Potamogeton malaianus.Based on variance and factor analysis,we discovered that there were significant differences in vegetation(P < 0.001),basement and digging food factors(P < 0.05).As to feeding habitat selection of Siberian Crane,the feeding efficiency factor was dominant with basement and food abundance factors followed.
