Nyenchen Tanglha
Nyainqentanglha mountain is one of the main mountains on the Qinghai Tibet Plateau, which runs across the central and eastern part of Tibet and is the eastward continuation of Gangdise mountain. The main peak of Nyainqentanglha mountain is 7111m above sea level. Namcuo is located in the northwest of Nyainqentanglha mountains, and Yangbajing Valley is rich in geothermal resources with many hot springs. It is said that the God of nyainqen Tanggula Mountain dominates hundreds of Tanggula mountains across northern Tibet, and is the most important Dharma protector in the world. Bon and Buddhist believers worship this mountain, believing that it is a quiet place and a happy gathering place for those who practice.
Legend of Namco and nyainqen Tanggula: nyainqen Tanggula and Namco are a loving couple who live in the beautiful northern Tibetan Plateau and are inseparable from each other. One day, Nianqing Tanggula went to another ranch to find the lost cattle and sheep, and met the gorgeous girl yam Zhuo yongcuo. Nianqing Tanggula couldn't help falling in love with yam Zhuo yongcuo, forgetting everything and his wife Namco who was waiting for him to go home. Namu mistakenly thought that her husband was in danger, weeping day and night, and finally turned into a clear lake. Day by day, Nianqing Tanggula suddenly thought of his wife. He rushed home with guilt and eagerness, and saw Namucuo, who had become a lake. His regret and self blame made him stand by the lake day and night without sleep. Later, he became a beautiful snow mountain, waiting by her side day and night, and the lonely Yangzhuo yongcuo also became a beautiful Yanghu.

Nyainqentanglha mountains
Nyainq ê ntanglha Shanmai is a fault block mountain located in Tibet Autonomous Region of China. It runs through the middle and east of Tibet, which is the eastward continuation of the Gangdise mountains. The southeast extension connects with the boshula mountains in the southwest of the Hengduan Mountains, and the central part protrudes slightly to the north. At the same time, Tibet is divided into three regions: Northern Tibet, southern Tibet and southeastern Tibet. In the southeast, it is close to Namjagbarwa peak at the great bend of Yarlung Zangbo River.
According to Yongzhong's Bon materials, nyainqentanglah is one of the three sacred mountains (Gangdise, nyainqentanglah and majixueshan) in Tibet, one of the nine sacred mountains and the top of the thirteen sacred mountains. It is said that Namco and nyainqentangla were once a loving couple. According to the records of Yongzhong Bon Dharma protection Scripture, family history and sacred mountain sacrifice, tangla is one of the sacred mountains of Yongzhong Bon religion, one of the four dependents of mother and son Dharma protection, as well as a famous and influential holy mountain in ancient Tibetan cultural history. Namtso is the holy land of the five riding sheep Dharma mother and son of Yongzhong sect, and also the Ming imperial concubine of tangla mountain. It and Namtso are the main holy places for practitioners.
The Nianqing Tanggula Mountain area is controlled by the Nujiang fault zone and the Yarlung Zangbo River fault zone in the east-west direction. The compression fault fold is a high mountain system with an average altitude of more than 6000 meters. Its ridge line is located to the west of Dangxiong Yangbajing, with a total length of 1400 kilometers, an average width of 80 kilometers, and an altitude of 5000-6000 meters. The main peak of Nianqing Tanggula peak is 7111 meters above sea level, and it is snowy all year round.
The Nyainqentanglha mountains are also the largest glacier area in the southeast of the Tibetan Plateau. The western section is the boundary between the inner flow area and the outer flow area, and the eastern section is the watershed between the Yarlung Zangbo River and the Nujiang River. The northwest side is the North Lake area of Tibet, the largest of which is Namco Lake.
It is said that there is a mysterious Crystal Palace in nyainqentanglah mountain. There are all kinds of gems on the door of the palace. The bottom of the palace is the sea of dew. The middle part is covered with iridescent fog. There are white clouds on the top of the palace. The rain and dew fall from time to time, and flowers bloom around it.
geographic information
The Nyainqentanglha mountains are nearly east-west. From the end of the Gangdise mountains at about 90 ° east longitude in the west, it extends to the northeast, and turns to the southeast with the NW trending fault zone, connecting with the boshula mountains in the northwest of Hengduan Mountains. In the southeast, it is close to Namjagbarwa peak at the great bend of Yarlung Zangbo River. The mountain range was formed in the late Yanshanian movement with complex geological structure. It is a series of eastward thrust folded mountain belts. Deep faults pass through the south side of the mountain belt. The west part is fault block mountain, and the south side of Dangxiong basin is a fault depression. Therefore, the south side is steep with a relative elevation difference of about 2000 meters, and the terrain is magnificent; the north side is gentle with a relative elevation difference of about 1000 meters.
There are three main ridges in Nyainqentanglha mountain: West Ridge, East Ridge and South Ridge. Influenced by topography, the development of glaciers in this area is greatly restricted. Near the north slope, there are mainly transverse valley glaciers and suspended glaciers, and the tip of the suspended glacier tongue is often as high as 5700 meters. There are two glaciers lying in the canyons on both sides of the north and the south, straight down, with many ice steep walls and light and dark cracks, which are extremely dangerous and spectacular. The grain snow line in this area is also higher than that in other areas, reaching more than 5800 meters
.
Landslides, landslides and debris flows are frequent, and they are the main debris flow outbreak areas in Tibet. For example, the famous Guxiang debris flow near Bomi is a major obstacle on the Sichuan Tibet highway.
At the end of the tertiary and Quaternary, the Nyainqentanglha mountain area was controlled by the Nujiang fault zone and the Yarlung Zangbo River fault zone in the east-west direction. The rice fold of the fault was compressed and rose intermittently and strongly, forming a high mountain system with an average altitude of more than 6000 meters.
In 1955, Li Pu et al. Discovered a strongly deformed gneiss in lengqingla area on the west side of the main peak of nyainqentangla mountain, named nyainqentangla gneiss series, and speculated that it was formed in Precambrian. Although some isotopic geochronological data indicate that the Nyainqentanglha gneiss is not a Precambrian basement, many scholars believe that it was formed in Precambrian or Presinian. One of the main reasons for the above argument is the unclear field geological relationship and the lack of reliable chronological data to constrain its formation age. The 1:250000 Regional Geological Survey of Dangxiong County Sheet in Tibet shows that the Nyainqentanglha gneiss series is composed of dioritic orthogneiss formed by intrusive rocks and felsic paragneiss formed by supracrustal rocks.
Climatic characteristics
Because Nyainqentanglha peak is located in the hinterland of the mainland, the barrier effect of the mountains blocks the cold current in the northwest and the warm current in the Indian Ocean, which basically belongs to the semi-arid continental climate, with annual precipitation between 300-400 mm. The rainy season is from the middle of May to the middle of September every year. During this period, 80% - 90% of the annual precipitation is concentrated. The weather phenomenon in rainy season is also very complex and changeable. There are often showers, hail, thunderstorms, lightning and other weather phenomena in a day.
The average temperature from west to East is 0-8 ℃, 10-18 ℃ in July, 10-0 ℃ below zero in January, and the annual range is 16-20 ℃.
Water system
The Nyainqentanglha mountains, with an area of 7536 square kilometers, is the largest glacier area in the southeast of Qinghai Tibet Plateau. Glaciers in the eastern part of the mountain range are concentrated, accounting for 5 / 6 of the total area of glaciers in the whole mountain range, and 90% of them are distributed on the windward slope in the south, which is one of the marine glaciers concentrated areas in China. Among them, 27 glaciers are more than 10 kilometers long, and many of them have reached the end of the forest. For example, the Kaqin glacier in bayugou, Yigong, is 33 kilometers long, with an altitude of 2530 meters at the end of the glacier. It is the largest glacier in Tibet and the largest marine glacier in China.
The source of 5100 glacier mineral water in Tibet is located in the south of Nyainqentanglha mountains and the north of Dangxiong fault basin. There are many ancient glacial relics, such as ancient ice bucket, U-shaped trough valley, end moraine dike, yangbeishi, moraine mound, glacial erosion lake and barrier lake (such as ranwucuo and yigongcuo).
Namco, the third largest salt water lake in China, is located at the foot of the mountain in the northwest of its main peak, which is the highest Lake in the world. At the south foot of its main peak is the beautiful Yangbajing valley,
Since the temperature rise is the main factor affecting the glacier retreat in nyainqentanglah mountains in the 21st century, it will have a significant impact on the regional hydrology and ecological environment.

Botany
The western part of the mountain range is located in the semi-arid climate area, where continental glaciers are developed. The area is small and the scale is limited. The height of snow line rises to 5700 meters. However, the western part of the mountain range is an important geographical boundary on the Qinghai Tibet Plateau. Like the Gangdise mountain range, it is not only the watershed between the internal and external water systems, but also the boundary between the cold climate zone and the warm (cool) climate zone on the plateau. The Qiangtang plateau to the north of the boundary is dominated by alpine grassland landscape, and the land use is dominated by animal husbandry; to the south of the boundary is commonly known as the "Southern Tibet area", which is the subalpine grassland and mountain (Valley) xerophytic shrub grassland landscape, with concentrated planting, and is known as the "granary of Tibet".
In terms of the vertical differentiation of mountain natural landscape, the west section is also relatively simple, generally with alpine grassland or meadow as the base band, connected with alpine frost weathering zone, without forest zone; the vertical band spectrum structure of the east section is more complex, belonging to marine humid type, dominated by Picea and Abies in mountain cold temperate dark coniferous forest zone, with the upper limit of 4400 meters above sea level. Coniferous forest belt has the characteristics of fast growth and high volume. For example, the spruce forest in Bomi area is 1500-2000 cubic meters per hectare, which is one of the main forest producing areas in Tibet. There are also evergreen broad-leaved forests and Tsuga Tsuga forests represented by Quercus alpina and Cyclobalanopsis glauca in warm and hot areas such as Yigong and Tongmai. Above the forest belt are alpine shrub meadow and alpine grass
