igital elevation model (DEM) was built in the research. DEM, slope model and bamboo distribution model formed digital terrain model (DTM) together. DTM was applied very well in the research of Giant Panda Habitat. Comparing with the real panda distribution area of the survey result in 1974, the area of potential panda habitat, which was formed from DTM according to three criteria (elevation, slope and bamboo area), is bigger and almost double. The suitability assessment of 754 km 2 potential panda habitat shows 205 km 2 as most suitable habitat, 297 km 2 as moderately suitable habitat and 252 km 2 as marginally suitable habitat for Giant Panda.
