When is a good time to go to Lop Nur in Urumqi?

The best time of Lop Nur in Urumqi: June-September.

Lop Nur is located at the eastern end of Tarim Basin. From satellite photos, we can see ancient coastal relics that look like the outline of ears. It is a mysterious land of 9.6 million square kilometers in China.

Lop Nur is the largest lake in Xinjiang, also known as Lop Nur. Robnor is a Mongolian phonetic translation, which means a watery lake. In the first century A.D., Hanshu described it as a 300-mile-wide pavilion that did not increase in winter and summer. During the Warring States Period, Shan Hai Jing called it Zeze. Hanshu Biography of the Western Regions is also called Prehai, which is 300 miles wide, meaning that its length or width can reach 300 miles away. This range coincides with the outermost lake embankment seen in the satellite photos, with an area of at least five or six thousand square kilometers. In the Northern Wei Dynasty, the lake shrank and was nearly round. According to Zhu, it is more than 400 miles wide, which is similar to the shape of the lake embankment in the middle of the satellite photo. During the Sui and Tang Dynasties, the lake surface shrank slightly, and the "Sha Zhou Tu Jing" recorded Zhou Guang 400. At the end of Wei Dynasty, it was further reduced to 80-90 miles from east to west (explored by Liu Qinghe and others). 1942 Xinjiang landform record area is 2520 square kilometers. To 1966, the north-south length is only 100 km, and the east-west width is only 3 ~ 16 km (sand control research).

Lop Nur is the terminal lake of Tarim River, Peacock River and Shule River, and its water source is mainly supplied by these rivers. Lop Nur dried up because of the redistribution of river runoff by human economic activities. Since the mid-Western Han Dynasty, the middle and upper reaches of these rivers have been heavily cultivated and irrigated, and the amount of water injected into lakes has gradually decreased. Especially after liberation, large-scale land reclamation led to a sharp decrease in river drainage. Tarim River was cut off from Arakan, and Peacock River gradually dried up from Yingpan. As early as the mid-Qing Dynasty, there was no afterglow from Shule River to Lop Nur, making it a completely dry world.

In the Qing Dynasty, Amitabha went deep into the lake area and wrote down the name of the field in Heyuan, which is recorded in Volume 9: Luobnuoer is a giant river in the western region, surrounded by mountains and rivers in the north and west of the Near East, with six or seven tributaries, 5,000 cotton fields and 4,500 miles of water, and the rest of the sand is poor, and the hermits are not counted. Writing from the mountains, all the twists and turns in the loop tend to return to Nur, which is hundreds of miles from east to west and hundreds of miles from northwest. It is neither surplus nor shrinking in winter and summer.

Vae, a geographer, pointed out in the Waterway Map of the Western Regions that the Tarim River flows into the Peacock River and into Lop Nur. Italian businessman Kyle Poirot, Russian explorer HM Poolsi Varski, Swedish geographer Sven Hedin, American Goldington, British Stein, Japanese Orange Ruichao and French Bonvallot have all been to Lop Nur and left wonderful descriptions.

1930- 1934 In China, scientists Huang Wenbi and Chen Chongqi made a field trip to Lop Nur and measured the map. After the founding of New China, China Academy of Sciences organized a large-scale investigation of Lop Nur in 1959 and 198 1 year.

The mystery of Lop Nur lies in the unique harsh environment. Heat, drought, sandstorm, Ya Dan and salt crust prevent people from approaching it, which casts a mysterious curtain on Lop Nur. The annual precipitation here is less than10 mm. In some places, the water does not drop for several years, but the evaporation is as high as 3000 mm or more, which is hundreds of times more than the precipitation!
