What is the common name of Dunhuang Crescent Spring? Crescent Spring, known as Shajing in ancient times and Yaoquan in common name, has been one of the "Eight Scenes of Dunhuang" since the Han Dynasty, and is called "Yue Quan Che Xiao".

Causes and pictures of the formation of crescent spring How is the crescent spring formed?

Crescent spring, called manhole in ancient times, is surrounded by Mingsha Mountain, so it is named because it looks like a crescent moon.

The uniqueness of Crescent Spring is that it is surrounded by sand mountains, and the quicksand and spring water are only separated by tens of meters, but they live in peace and set each other off.

Sand and water are hard to exist, but for thousands of years, Mingsha Mountain and Crescent Spring have coexisted with sand and water. In the environment where the annual precipitation is only 40 mm and the evaporation is as high as 2400 mm, the spring water will not dry up; In the case of strong winds and sandstorms, sand does not enter spring.

"Dunhuang Miscellanies" said: "Sand flies with the wind, and spring reflects the moon without dust.

Times have changed, and visitors can't stay long.

"The spring emperor is covered with aquatic plants, and the fish are swimming and playing in the spring, which is amazing.

There are four explanations for the origin of Crescent Moon Spring:

One day, this ancient river stayed in the lake.

It is considered that Crescent Spring is the ancient channel of Danghe River nearby. A long time ago, the Danghe River was diverted, and most of the ancient rivers were submerged by quicksand. Only a section of crescent spring is low-lying and flows into the lake due to underground diving.

The lake is constantly replenished by underground undercurrents, so it will not be exhausted.

In 1950s, it was measured that the water surface of Crescent Spring was 2 18m long from east to west, 54m wide from north to south, with an average water depth of 5m and a water depth of more than 7m.

Erri fault seeps into spring water.

It is considered that there is an east-west fault on the south side of Crescent Spring. The footwall of the fault raises the groundwater aquifer. When the footwall drops to the nearby groundwater level, the groundwater flows outward into the spring.

Three days of wind erosion lake.

That is, with the intensification of wind erosion, when the original wind erosion depression reaches the depth of groundwater level, a spring lake is formed in the inner bay of the crescent sand dune.

Because the sand mountain around Crescent Spring is high in the south and low in the north, the wind blowing into the depression around the mountain from the east will be upward, and the sand will always roll up along the ridge and sand surface under the action of the wind, so the sand will not be blown into the spring, and the sand mountain will always keep the shape of the ridge like a blade, forming the wonders of the sand spring.

Four days of manual excavation.

It is believed that the shapes of crescent moon spring and half crescent moon are lifelike, which seems to be the result of artificial deliberate modification. In addition, there is a record of "manhole" in ancient books, because it must be the result of human labor.

Where is Crescent Moon Spring? Yueya Spring is located at the northern foot of Mingsha Mountain, seven kilometers south of Dunhuang City, Gansu Province, covering an area of about 200 square kilometers. Crescent Spring is a national key scenic spot. Surrounded by Mingsha Mountain, it is about150m long and 50m wide, so it is named after the water surface resembles a crescent moon. The source of Crescent Moon Spring is Danghe River. With the continuous filling of the river, surrounded by yellow sand, the spring water is also clear and beautiful, and it is amazing that it will not dry up for thousands of years. Unfortunately, in recent years, Danghe River and Crescent Spring have been cut off, and the current situation of spring water can only be maintained manually. Pavilions and pavilions have been built by crescent spring, plus undulating sand mountains, clear spring water and brilliant sunset. The scenery is quite good, don't miss it!
