摘　　要：珠穆朗玛峰国家级自然保护区是世界高山极高山地貌景观的典型代表,然而其偏远艰险的区位条件,影响了对其地形特征和地貌景观的全面认识。数字高程模型提供了从汇水盆地到大洲大陆不同尺度但格式统一的观测数据,能够为珠峰地区地表过程研究提供数字地形分析基础。基于ASTER GDEM2,采用条带高程剖面指标计算,进行珠峰自然保护区流域数字地形分析,探索高山极高山流域地貌景观类型的空间分布规律。结果显示,珠峰自然保护区由7条流域组成,条带高程剖面特征明显指示三个地貌景观区。条带高程剖面传递的地形起伏形态信息,对流域地貌景观类型的辨识具有很好的指示意义。Mt.Qomolangma national nature reserve is a typical landform landscape with representative of the world's alpine and extremely alpine.However,its remote and dangerous location conditions affect the comprehensive understanding of its topographic features and landform landscape.The digital elevation model provides the observation data of different scales with the same format from the basin to the continent,which can provide the basis of digital terrain analysis on the surface process research in the Qomolangma region.Based on ASTER GDEM,we analyzed the digital topography of the Qomolangma nature reserve watershed by using the swath elevation profile index in this paper,and explored the law of spatial distribution of geomorphic landscape types in the alpine and extreme alpine watersheds.The results show that Qomolangma nature reserve is composed of seven watersheds,and the swath elevation profiles clearly indicate three landform landscape areas.Moreover,the relief information conveyed by the swath elevation profile is of great significance to the identification of watershed geomorphic landscape types.
