Introduction to Tibet: Tibet not only has a unique scenery of plateau snow, but also has a charming southern style, and the humanistic landscape integrated with this nature also makes Tibet truly unique in the eyes of travelers. Up to now, there are still many Tibetans whose living customs are far from those of modern people outside the plateau. It is precisely because of the distance that everything in Tibet has ornamental value.

Xizang Autonomous Region is one of the five ethnic autonomous regions in the People's Republic of China, which was founded on September 1, 1965.

Xizang Autonomous Region is located in the southwest frontier of China, southwest of Qinghai-Tibet Plateau. It borders Xinjiang Uygur Autonomous Region and Qinghai Province in the north, Sichuan Province in the east, Yunnan Province in the southeast, Myanmar, India, Bhutan, Nepal and other countries in the south, forming a border line of nearly 4, kilometers between China and these countries. The land area of the whole region is more than 1.22 million square kilometers, accounting for about 12.8% of the total area of the country.

topography and mountains

Xizang Autonomous Region is the main part of the Qinghai-Tibet Plateau with an average elevation of over 4, meters, and is known as the "roof of the world". The terrain here is complex, which can be roughly divided into three different natural areas: the northern Tibet Plateau is located between Kunlun Mountain and Tanggula Mountain, Gangdise Mountain and Nyainqentanglha Mountain, accounting for two-thirds of the total area of the autonomous region; Between the Gangdise Mountain and the Himalayas, where the Yarlung Zangbo River and its tributaries flow, is the southern Tibetan valley; East Tibet is an alpine valley area, which is a series of high mountains and deep valleys that gradually turn from east-west to north-south, and is a part of the famous Hengduan Mountains. Geomorphology can be basically divided into six types: extremely high mountain, high mountain, Zhongshan, low mountain, hilly and plain, as well as periglacial landform, karst landform, aeolian landform and volcanic landform. The Himalayas, which meanders on the south side of the Tibetan Plateau, consists of many parallel mountains which are similar to the east-west direction. Its main part is on the border line between China and India and Nepal, with a total length of 2,4 kilometers, a width of about 2-3 kilometers and an average elevation of over 6, meters. Mount Everest, the world's highest peak at an altitude of 8844.43 meters, stands on the Sino-Nepalese border in the middle of the Himalayas. Within more than 5, square kilometers around it, there are 4 peaks over 8, meters and 38 peaks over 7, meters.

rivers and lakes

in Xizang Autonomous Region, there are more than 2 rivers with a basin area of more than 1, square kilometers and more than 1 rivers with a basin area of more than 2, square kilometers. The famous rivers are Jinsha River, Nujiang River, Lancang River and Yarlung Zangbo River. Tibet is also a China province with the largest distribution of international rivers, and the headwaters of famous rivers in Asia, such as Ganges, Indus, Brahmaputra, Mekong, salween and Irrawaddy, are all here. The water sources of rivers in Tibet are mainly composed of rainwater, snow melt water and groundwater, with abundant flow, low sediment concentration and good water quality. The Yarlung Zangbo River, the largest river in Tibet, originates from the Jemayangzong Glacier in Zhongba County at the northern foot of the Himalayas and flows into India through Luoyu area, which is called Brahmaputra River. The Yarlung Zangbo River (in China) has a total length of 2,57 kilometers, a drainage area of more than 24, square kilometers and an average elevation of about 4,5 meters, making it the highest river in the world. The Yarlung Zangbo River Grand Canyon is 5382 meters deep, which is the deepest canyon on earth. The valley bottom of the Grand Canyon is only 74 meters at its narrowest point and about 2 meters at its widest point, with a total length of 37 kilometers.

The vast Tibetan Plateau is dotted with more than 1,5 large and small lakes, among which Namco, Selin Co and Zhaxi Co cover an area of over 1, square kilometers. There are 47 lakes over 1 square kilometers. Namco is also the highest lake in the world. The lake covers an area of 24,183 square kilometers, accounting for about one third of the total area of lakes in China. Tibet Plateau is not only the largest lake-concentrated area in China; It is also the plateau lake area with the highest lake surface, the largest range and the largest number in the world. There are many lakes and saltwater lakes here, but few freshwater lakes. There are 17 lakes with an altitude of more than 5, meters, all of which have an area of more than 5 square kilometers.

Climatic characteristics

The air is thin, the air pressure is low, and the oxygen content is low

The solar radiation is strong, the sunshine time is long

The temperature is low, and the daily temperature difference is large

The whole year is divided into obvious dry season and rainy season

The climate type is complex, and the vertical change is great

The complex and diverse topography of the Tibetan Plateau has formed a unique plateau climate. In addition to the general trend of cold and dry northwest and warm and humid southeast, there are various regional climates and obvious vertical climatic zones. Proverbs such as "ten miles is different from the sky" and "one day has four seasons" reflect these characteristics. Compared with most parts of China, Tibet has thin air, abundant sunshine, low temperature and less precipitation. Every cubic meter of air in Tibet Plateau contains only about 15-17 grams of oxygen, which is equivalent to 62% to 65.4% of that in plain areas. Tibet is the place with the largest solar radiation energy in China, which is twice or one third more than the plain area at the same latitude? Sunshine hours are also the high-value center in China, with the average annual sunshine hours in Lhasa reaching 321 hours. The temperature is low, the annual temperature difference is small, but the temperature difference between day and night is large. The average annual temperature and the hottest monthly temperature in Lhasa and Shigatse are 1-15 degrees Celsius lower than those in Chongqing, Wuhan and Shanghai with similar latitudes. The annual temperature difference in Lhasa, Qamdo and Shigatse is 18-2 degrees Celsius? In places above 5 meters above sea level in Ali, in August, the daytime temperature is above 1 degrees Celsius, while the nighttime temperature drops below zero degrees Celsius. The seasonal distribution of precipitation in Xizang Autonomous Region is uneven, and the boundary between dry season and rainy season is very obvious, and it rains many nights. The annual precipitation gradually decreases from 5 mm in the southeast lowlands to 5 mm in the northwest. From October to April of the following year, the precipitation only accounts for 1% to 2% of the whole year; From May to September, the rainfall is very concentrated, generally accounting for about 9% of the annual precipitation.
