Digital terrain model(DTM) was build from combining information of digital elevation model(DEM),river model,model of lake and home range around lakes,and vegetation model.DTM was applied to search potential habitat of Bar-headed Goose (Anser indicus) by using the overlap functions of Geographic Information System(GIS).The locations of potential habitat of Bar-head Goose were checked by satellite-tracking data of eleven bar-headed geese banded in Qinghai Lake.The result showed that total of 275 sites of bar-headed goose potential habitat was located.The potential habitat consists of lake and home range around the lake.The total area of the lake waters are about 10 306.4 km2 and 59 sites were verified that bar-headed goose stopped over there for rest.Around some lake there was little bar-headed goose track-points which may be obtained on the fly,and it can’t be confirmed that they stopped over there at present.Breeding sites,stopovers in process of migration,and wintering sites of bar-headed goose showed higher concentrations and its’ migration route is relatively stable.
