三江源自然保护区地形地貌图
- 三江源区是青藏高原的腹地和主体，以山地地貌为主，山脉绵延、地势高耸、地形复杂，海拔为3335~6564m，最低海拔位于玉树藏族自治州东南部的金沙江江面，平均海拔4400m左右。海拔4000~5800m的高山是保护区地貌的主要骨架。主要山脉为东昆仑山及其支脉阿尼玛卿山、巴颜喀拉山和唐古拉山山脉。由于受第四纪冰期作用和现代冰川的影响，海拔5000m以上的山峰可见古冰川地貌。 源区中西部和北部呈山原状，起伏不大、切割不深、多宽阔而平坦的滩地，因地势平缓、冰期较长、排水不畅，形成了大面积沼泽。东南部高山峡谷地带，切割强烈，相对高差多在1000m以上，地形陡峭，坡度多在30°以上。
