The elevation of Turpan Basin is-155m, which means the elevation of Turpan Basin is lower than the sea level 155m.

Altitude refers to the vertical distance above sea level at a certain place on the ground. It is the height difference between a place and sea level, and is usually calculated based on the average sea level. The starting point of altitude is called altitude zero or leveling zero, which is the average sea level of a coastal location. It is obtained by averaging the position of the sea surface according to the records of local tide gauge stations for many years.

In height, above sea level is indicated by+,below sea level by-.

Extended data:

Turpan is an olive-shaped intermountain basin in the eastern Tianshan Mountains, surrounded by mountains. The basin starts from Alashan Goukou in the west and ends at the west of Qijiaojing Canyon in the east, with a length of 245 kilometers from east to west. In the north is the foothills of Bogda Mountain; South to Kurutag Mountain, about 75 kilometers wide from north to south.

The discovery of ancient fish and dinosaur fossils here proves that it was once a sea. Due to the crustal movement, it gradually turned into land and the basin began to form.

Turpan basin has experienced Jurassic, Cretaceous, Tertiary and Quaternary geological ages, and is an ancient basin gradually depressed. Especially during the Himalayan orogeny 30 million years ago, Bogda Mountain in the northern margin of the basin rose sharply, while Kuruktag Mountain in the northern and southern margins of the basin rose slightly, and the fault between the two mountains collapsed, eventually forming an asymmetric basin with high north, low west and narrow east. There are Flame Mountain and Wula Mountain in Bolto in the middle, which cross the territory and divide the local area into two parts: south and north.
