The largest lake in China.

Qinghai Lake is called "Cuowenbu" (meaning "blue sea") in Tibetan. Located in the northeast of Qinghai-Tibet Plateau, Qinghai Province, it is the largest inland lake in China. It is formed by the fault subsidence among Datong Mountain, Sun Moon Mountain and Nanshan Mountain in Qilian Mountain and Qinghai Province.

1908, Russian ke Zlov speculated that the water level of the lake was 3,205 meters and the lake area was 4,800 square kilometers. Surveying and mapping data in 1950s showed that the lake area of Qinghai Lake was more than 4,568 square kilometers. The topographic map published in 1970s measured that the water level of the lake was about 31.95m.. The lake area is 4473 square kilometers;

1988, the water level is 3 193.59 meters, and the lake area is 4282 square kilometers. In 2000, through the analysis of remote sensing satellite data, the area of Qinghai Lake was more than 4,256.04 square kilometers. August 20 13, Qinghai Lake covers an area of 4,337.48 square kilometers. [4]? The volume of the lake is 73.9 billion cubic meters, the longest is about 104 km, the widest is about 62 km, the maximum water depth is 3 1.4 m, the average salinity of the lake is 12.32 g/L, and the salt content is 1.25%. [5]?

20 17 In August, the area of Qinghai Lake was 4,435.69 square kilometers, an increase of 60. 19 square kilometers over the same period of last year, and an average increase of10/.54 square kilometers over the same period of last year (2005-2016). .

Reasons for the formation of Qinghai Lake:

The tectonic faults in Qinghai Lake make the lake depressed, and the edge of the lake basin is mostly connected with the surrounding mountains by faults. In the early days of the lake's formation, it was originally a large freshwater lake, which was connected with the Yellow River system 200-200 million years ago. At that time, the climate was mild and rainy, and the lake was discharged into the Yellow River through the Daotang River in the southeast, which was an outflow lake.

Up to 6,543,800+300,000 years ago, due to neotectonic movement, the surrounding mountains rose strongly. Since the end of Pliocene, Sun Moon Mountain and Bison Mountain in the east of the lake have risen rapidly, blocking the Daotang River that has been injected into the Yellow River, forcing it to flow into Qinghai Lake from east to west, resulting in Gahai Lake and Erhai Lake, which are further divided into sub-lakes such as Haiyan Lake and Shadao Lake.

Bird resources in Qinghai Lake;

By August of 20 14, the number of birds in Qinghai had increased to 222, belonging to 35 families of 14, with a total number of more than16,000, including 2 geese1300, 45,000 brown-headed gulls, fish gulls and cormorants. In addition, there are guanqian duck, red duck, merganser duck, magpie duck, white-eyed duck, spotted duck, needle-tailed duck, swan, demoiselle crane and black-necked crane.

Historical legends of Qinghai Lake:

/kloc-More than 0/000 years ago, Tang married Fan, and Princess Wencheng married Songzan Gambu, the king of Tubo. Before leaving, the king of Tang gave her a mirror that could reflect the scene of her hometown. On the way, the princess missed her hometown, so she took out the mirror of the sun and the moon and saw Chang 'an, her long-lost hometown, with tears streaming down her face.

However, the princess suddenly remembered her mission and decided to throw away the sun and moon mirror. Unexpectedly, when the mirror landed, it flashed golden light and turned into Qinghai Lake. Others say that the youngest son of the East China Sea Dragon King attracted 108 lakes and merged into this vast West Sea, so he became the West Sea Dragon King.
