Wetlands are important environments that serve as irreplaceable habitat for numerous wildlife species by providing them breeding and resting. Millions of migratory birds, including endangered Siberian Crane, migrate to the Poyang Lake wetland at the end of autumn and the beginning of winter every year when the lake level is low and the grassland is emerged. The Poyang Lake natural wetland with an area of 3306 km² is one of the most important international wetland and it also is the largest habitat for wintering birds in East Asia. In this research, the data from field survey on wintering birds around Poyang Lake wetland was used to define the habitat landscape for the wintering wild birds. Then 11 remotely sensed images at different lake levels were used to outline the habitat distribution by combining unsupervised classification with visual interpretation. The landscape spatial patterns of the wintering birds' habitat were analyzed with landscape metrics such as patches area (PA), mean patch area index (MPAI), largest patch index (%) (LPI), area-weighted mean shape index (AWMSI), perimeter area fractal dimension index (PAFRAC) and contagion index (CONT). And we conclude that: 1) the wintering migrant birds in Poyang Lake are always forage or rest in the shallow and still water, flat mud and wetland vegetation. 2) Habitat for migrant wild birds was affected by the lake level apparently. With water level in Poyang Lake increasing from 5 m to 15.6 m, the area of habitat for migrant wild birds will decrease from about 2300 km² to 530 km² gradually. And lake level can also exert significant influence on the composition of habitat types for winter migrant water- birds. But it doesn' t mean that the frequently happened drought in the Poyang Lake wetland in recent years will benefit to the wintering wild birds in Poyang Lake wetland. In fact, the changed hydrological characteristics (drought happened frequently in autumn or winter) had been causing the hygrophytes community succession with terrestrial plant in Poyang Lake wetland. 3) With lake level in Poyang Lake increasing from 5 m to 15.6 m, the landscape fragmentation will be increasing and connectivity will be decreasing that means maintaining a higher lake level will be unfavorable for the protection of winter migrant wild birds.
