中国西藏的西部,有一块号称“世界屋脊上的屋脊”的辽阔高原,它的海拔高度达4400米,总面积约占西藏的三分之一。但是,这里的人口密度,却仅仅为每平方公里0.16人,境内纵横分布着上千公里的“无人区”,成为本来就充满着神秘感的西藏高原上最富有吸引力的一方秘境——这就是著名的阿里高原。 In western Tibet of China, there is a vast plateau called “the ridge on the roof of the world,” with an elevation of 4,400 meters and a total area of ​​about one third of Tibet. However, the population density here is only 0.16 people per square kilometer. There are thousands of kilometers of “no man’s land” distributed vertically and horizontally in the country. This has become the mysterious secret of the most attractive side of the Tibetan Plateau - This is the famous Ali plateau.
