摘要
本文建立了卧龙自然保护区２０００ｋｍ２范围的数字地形模型，并将其应用在濒危珍稀动物大熊猫的生境研究上。通过计算机叠加大熊猫可分布的高度、坡度及竹子分布区域，获得了大熊猫在卧龙自然保护区内的潜在生境区，其比实际的熊猫分布范围大出近一倍，文章还对潜在生境的适宜性进行了划分。
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 km2 potential panda habitat shows 205 km2 as most suitable habitat, 297 km2 as moderately suitable habitat and 252 km2 as marginally suitable habitat for Giant Panda.
