位于西藏安多县境内的唐古拉山主峰各拉丹冬,藏语意为“高高尖尖的山峰”,海拔6621米。在其南北长50公里、东西宽15至20公里的区域内,有30余座海拔6000米以上的冰峰,发育有130多条现代冰川。这里的冰川和积雪,是我国第一大河——长江的主要水补给来源,也是一处极为壮丽的景观。 Located in Andhra Pradesh, Tibet, the main peak of the Tanggula Mountains is Lardan Dong, meaning “high and sharp peak” in Tibetan language and 6621 meters above sea level. Within 50 km of its north-south area and 15-20 km of east-west width, there are more than 30 ice peaks above 6,000 meters above sea level, and more than 130 modern glaciers have been developed. The glaciers and snow cover here are the main source of water supply to the Yangtze River, the largest river in our country, and an extremely magnificent landscape.
