The habitat composition in the Han-river estuary, where white-naped crane(Grus vipio; endangered
migrating bird) spend winter, was analysed by the geographic information system(GIS). And the habitat use pattern
of white-naped crane collected by satellite tracking method was analysed. The % composition of seven habitat
categories of land cover classification was compared for the buffers of radii 100 m, 200 m, 500 m, and 1 km,
respectively, around the white-naped crane position point(n=228), and the statistical analysis was done using
chi-square test. The results showed no selective use of habitat area by white-naped crane in the buffers of 100 m,
200 m and 500 m, but showed clear selection of habitat use (p < 0.05) in the case of 1 km buffer.
