| 摘 要： | 建立了青藏高原地区的数字地形模型,并将其应用在斑头雁(Anser indicus)的潜在生境提取与分析中。通过数字高程模型、水系模型、湖泊及环湖活动区模型和植被模型的GIS叠置,提取了斑头雁的潜在生境,并对来自青海湖的11只斑头雁的卫星跟踪数据进行了验证分析。结果表明,斑头雁的潜在生境(湖泊与环湖活动区构成)共有275处(以湖泊为单位),湖泊水体总面积约为10306.4km2,59处生境已验证有斑头雁停留的踪迹,其中部分湖泊周围的验证点可能是斑头雁飞行时的定位点而不是停留定位点,目前还无法证实。繁殖地、迁徙停留地和越冬地比较集中,迁徙路线较固定。

| Abstract: | 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-... |
