我国的西藏自治区位于有“世界屋脊”之称的青藏高原,平均海拔4000米以上。那里空气稀薄而气候寒冷,高山积雪而湖泊纵横,自古以来就是我国的领土,是藏族古老的生存空间。 China’s Tibet Autonomous Region is located on the Qinghai-Tibet Plateau, known as the “roof of the world,” with an average altitude of 4,000 meters above sea level. Where the air is thin and the climate is cold, the mountains are snow-covered and the lakes are vertical and horizontal. It is the territory of China since ancient times and it is an ancient Tibetan living space.
