Why won’t Crescent Moon Spring disappear?

Why won’t Crescent Spring disappear?

Crescent Spring, known as Shajing in ancient times and commonly known as Yaoquan, has been one of the “Eight Scenic Spots of Dunhuang” since the Han Dynasty, and was named “Yuequanxiao” thorough". Crescent Moon Spring is nearly 100 meters long from north to south and about 25 meters wide from east to west. The spring water is deep in the east and shallow in the west. The deepest point is about 5 meters. It is curved like a crescent moon, hence its name. It is also known as "the first spring in the desert". . A clear spring with lingering ripples as green as emerald. The spring is in the quicksand, it does not dry up in drought, and the sand does not fall when the wind blows, which is a wonder. Scholars of the past dynasties have praised this unique mountain spring landform and desert wonders.

The crescent-shaped clear spring, with turquoise water, is like emerald inlaid on the gold-like sand dunes. There are thick reeds beside the spring, where the breeze blows, the blue waves ripple, and the water reflects the sandy mountains, making it a wonderful sight. There are many explanations for the mystery of why Crescent Moon Spring has been exposed to strong winds for hundreds of years without being covered by sand. Some people believe that this area may be the original Dang River bend, part of the Dunhuang Oasis. Due to the movement of sand dunes and the change of water channels, it became a separate body of water. Because the terrain is low, the water seeping underground continuously replenishes the spring, making it trickle endlessly and never dry up during drought. This explanation seems to be a reason why the Crescent Moon Spring has not disappeared, but it cannot explain why the flying sand does not fall into the Crescent Moon Spring.

It is said that Crescent Moon Spring was a tourist attraction as early as the Han Dynasty. In the Tang Dynasty, there were boats and temples by the spring. There was originally a group of simple, elegant and well-proportioned buildings on the south bank of the spring. From east to west, there were more than 100 buildings including the Empress Hall, Dragon King Palace, Bodhisattva Hall, Yaowang Cave, and Thunder God Tower. There are more than 100 colorful sculptures in each main palace and hundreds of murals. Plaques and inscriptions are hung in important halls, such as "The First Spring", "There is a Different World", "Semi-regular Spring", "Connecting Kunlun", "Mastering the Universe", etc. The calligraphy is elegant and can be called top grade. At that time, there were pavilions, pavilions, splendid temples, palace halls and colonnades, all built near the water. The trees are lush, the spring light complements the mountain scenery, and the ancient temples and temples are surrounded by incense all year round. In the past dynasties, poets traveled around, recited poems and chanted poems, and wrote many poems. According to historical records, in the fourth year of Yuanding in the Han Dynasty (113 BC), Emperor Wu of the Han Dynasty obtained a Pegasus in Wowa Pond. Later generations suspected that Crescent Moon Spring was the Wowa Pond of Han Dynasty, so they erected a stone tablet saying "Wowa Pond of Han Dynasty". "There are wild horses flying in the wind and sand on all sides, and a phantom dragon swimming in the pool." Therefore, the unique Crescent Moon Spring has become even more legendary.

The formation of Crescent Moon Spring mainly depends on three factors: the geological structure of Crescent Moon Spring itself, the topographic conditions of low-lying land and the high regional groundwater level. In the late 1940s, the groundwater level in Dunhuang City and its southern areas was about 10 meters higher than the current water level. Under this higher water level condition, groundwater in the northwest plain area entered the spring area through underground runoff and overflowed in the low-lying depressions. The high regional groundwater level is an important condition for the formation of Crescent Moon Spring, and it is also the basic guarantee for Crescent Moon Spring to remain dry for thousands of years.

The Crescent Moon Spring in history is not only "everlasting", but also has a huge water surface and depth. There are documented records that large ships could still be run here during the Qing Dynasty. At the beginning of the 20th century, someone came here to fish, and his travel notes said: "The water in the pool is extremely deep, and its bottom is sand. The depth is unfathomable." In the limited historical records and poems and songs, Crescent Moon Spring has always been a place with rippling blue waves and fish flying on the shallow bottom. , lush water and grass, and Mingsha Mountain complement each other. Among the local people, there are three treasures: iron-backed fish, seven-star grass and five-color sand. Until 1960, there was no major change in the spring water. The maximum water depth was 9 meters and the lake area was 22.5 acres.

In the mid-1970s, local land reclamation and pumping for irrigation, as well as the destruction of surrounding vegetation and soil erosion in recent years, caused the groundwater level in Dunhuang to drop sharply. As a result, the water level of Crescent Moon Spring dropped sharply. The lowest water storage time in Crescent Spring was in 1985, when the average water depth of Crescent Spring was only 0.7 to 0.8 meters. Due to the lack of water, people could leave when the spring bottomed out, and the Crescent Moon Spring also formed two small springs and no longer formed a crescent shape. This makes "Whether Crescent Moon Spring will disappear tomorrow" become the focus of many people's attention. Since then, Dunhuang City has adopted various methods to replenish Crescent Spring with water.

Since 2000, Dunhuang City has taken emergency measures to recharge river water around the Crescent Spring to replenish the water level of the Crescent Spring, thus temporarily preventing the Crescent Spring from drying up.

In 2004, the water level dropped to 1.3 meters, and the spring area was reduced to 7.8 acres.

At present, the water level of Crescent Moon Spring is hovering around 1 meter. If fundamental management is not carried out, Crescent Moon Spring, a world-class heritage, will be in danger of drying up.

With the 20 million yuan loan from the China Development Bank in place, the emergency treatment project for the declining water level of Crescent Spring will also start at the end of 2006. Crescent Spring will be rescued through various methods such as "water saving", "water replenishment" and "water diversion".

On January 10, 1994, Mingsha Mountain-Crescent Spring Scenic Area in Gansu Province was approved by the State Council to be included in the third batch of national scenic spots.

Due to the ecological deterioration of the surrounding areas, the water level of Crescent Spring in Mingsha Mountain in Dunhuang City has dropped by a total of 6 to 7 meters since the 1960s, and the water area has been significantly reduced. In order to save the magical desert landscape of Mingsha Mountain Crescent Spring, the Crescent Spring emergency treatment project with a total investment of 41 million yuan was officially launched in early 2007. The emergency treatment project builds four seepage fields around Crescent Spring to seep water into the ground. By raising the groundwater level around Crescent Spring, it maintains and improves the water level of Crescent Spring. This project is expected to be completed in May 2008, by which time the water level of Crescent Spring is expected to be stabilized and gradually increased.

With the Crescent Spring emergency treatment project in Dunhuang, Gansu Province partially put into use, the water level of Crescent Spring continues to rise. Recently, Crescent Moon Spring in Dunhuang has regenerated its "sub-spring", and the wonder of "three springs dependent on each other" has appeared. Why doesn't the water of Crescent Moon Spring dry up?

Someone maintains why Crescent Moon Spring can survive with the yellow sand?

Crescent Moon Spring is surrounded by high sand mountains, with a small lake shaped like a crescent moon in the middle. Mingsha Mountain makes noise when the wind blows, so it is called Mingsha Mountain. There is also a strange phenomenon here. Because of the terrain, the sand does not move down the mountain when the wind blows, but flows from the bottom up the mountain. Therefore, the Crescent Moon Spring never flows down the mountain. It will not be buried by the sand and is called a desert wonder. Crescent Moon Spring is most like a crescent moon on the fifth day of the Lunar New Year, falling in the yellow sand. The spring water is cool, clear, and delicious. It has been lying quietly in the embrace of the sand mountain for thousands of years. Although it is often attacked by strong winds and fierce sand, it still has rippling blue waves and gurgling water. It is well-deserved as the first spring in the desert! Crescent Moon Spring, a dream-like mystery, has never been submerged by quicksand or dried up by drought for thousands of years. There is this spring in the vast desert, this water in the black wind and yellow sand, and this scene in the midst of desolation. It captures the rhythm of heaven and earth, the magic of creation, and makes people intoxicated. "The sky is clear and blue, the Crescent Moon Spring is extremely beautiful, the Silver Mountain is surrounded by sand, and there is a pool of clear water with green ripples." "Crescent Moon Dawn" is one of the eight scenic spots in Dunhuang. Crescent Moon Spring is a national key scenic spot, one of the top 40 tourist attractions in China, and is known as the best desert spring in the world. The crescent-shaped clear spring has turquoise water, like emeralds, inlaid on the gold-like sand dunes. There are thick reeds beside the spring, where the breeze blows, the blue waves ripple, and the water reflects the sandy mountains, making it a wonderful sight. There are many theories about the mystery of why Crescent Moon Spring has been exposed to strong winds for hundreds of years without being covered by sand. Some people believe that this area may be the original Dang River bend, part of the Dunhuang Oasis. Due to the movement of sand dunes and the change of water channels, it became a separate body of water. Because the terrain is low, the water seeping underground continuously replenishes the spring, making it trickle endlessly and never dry up during drought. This explanation seems to be a reason why the Crescent Moon Spring has not disappeared, but it cannot explain why the flying sand does not fall into the Crescent Moon Spring. Why is there less and less water in Crescent Moon Spring?

Crescent Moon Spring is actually an open-air part of an underground river. The drop in water level indicates that the amount of river water has decreased or the amount of evaporation has increased.

The increase in annual average temperature will Increased evaporation,

The decrease in river water volume may be due to a decrease in source water volume or the presence of other branches diverting water.

Why should we protect Crescent Moon Spring and how to protect it?

"Clouds are manholes that last through the ages and will not be filled with sand." Shajing is the ancient name of Crescent Moon Spring. For thousands of years, it has been The beautiful scenery of Crescent Moon Spring writes a myth that will never dry up. According to the Beijing News, the water level of Crescent Moon Spring has dropped significantly in the past 30 years, and this key national scenic spot is slowly disappearing from our eyes. On April 8, the tamarisk and Elaeagnus trees that used to grow lushly by Crescent Moon Spring died.

Actual measurement data on April 9 showed that the maximum water depth of Crescent Moon Spring was only 1.0 meters, and the sea of ??sand submerged the Crescent Moon Spring to a depth of nearly 10 meters. It is urgent to protect Crescent Moon Spring.

According to reports, the Crescent Moon Spring, which is shaped like a crescent moon, is located about 5 kilometers south of Dunhuang City, Gansu Province. In 1994, Mingsha Mountain (recorded as Shajiao Mountain in ancient books) and Crescent Moon Spring were announced by the State Council as national key scenic spots. Most experts believe that Crescent Moon Spring is a remnant of the Gudang River. It is supplied by underground undercurrents and has managed to survive thousands of years of extreme drought and intense evaporation.

The water environment has deteriorated sharply in the past 30 years. What caused the water level of Crescent Spring to drop? The investigation found that the water level of Crescent Spring dropped due to both natural factors and man-made factors. The latter was the main and most direct reason for the drop of water level in Crescent Spring.

It is understood that in the 10 years from 1987 to 1997, the area of ??Crescent Moon Spring decreased from 13.5 acres to 8.5 acres, with an average annual shrinkage of 0.5 acres. The maximum water depth dropped from 4.2 meters to 2.0 meters, with an average annual decrease of 0.22 meters. The actual measurement data on April 9, 2006 showed that the maximum water depth of Crescent Moon Spring was only 1.0 meters. Ma Shengkai, director of the Crescent Moon Spring Management Office in Mingsha Mountain, told reporters: The current water area of ??Crescent Moon Spring is about 60,000 square meters. After two sand and dredging operations in 1986 and 1999, and five years of recharge and water replenishment, 500 people are attracted every year. It took 10,000 cubic meters of river water to be saved. Despite this, the water level of Crescent Moon Spring still drops by about 15 centimeters every year.

Relevant experts suggest that "major surgery" is needed to protect Crescent Spring: in the long run, strict control of groundwater extraction to recover the groundwater level and maintain the original dynamic balance of groundwater in the Dunhuang Basin is the key to management. The root cause of the problem of falling spring water levels.

End point: Why is the Crescent Spring in Guyuan City crescent-shaped? Explain in detail if possible. urgent!

Today, there are four explanations for the origin of Crescent Moon Spring:

One is a lake remnant of an ancient river channel. Think of the crescent moon

Dunhuang Crescent Moon Spring Autumn Color

The spring is an ancient river channel of the nearby Dang River. A long time ago, the Dang River changed its course, and most of the ancient river channels were submerged by quicksand. Only a section of the Crescent Moon Spring is Lower, due to the exposure of underground water, it collects into a lake. The lake water is constantly replenished by underground currents, so it will not dry up. Measured in the 1950s, the water surface of Crescent Moon Spring is 218 meters long from east to west, and 54 meters wide at its north-south point. The average water depth is 5 meters, and the deepest point is more than 7 meters.

The second is fault seepage spring. It is believed that there is an east-west fault on the south side of Crescent Spring. The hanging wall of the fault raises the underground aquifer. When the footwall drops to the nearby phreatic surface, the undercurrent flows out to form a spring.

The third one is Wind Erosion Lake. That is, as wind erosion intensifies, the original wind-eroded depression forms a spring lake in the inner bay of the crescent-shaped dune when it reaches the depth of the water surface. Because the sand mountains surrounding Crescent Moon Spring are high in the north and south and low in the middle, the wind blowing into the depression surrounding the mountains from the east will move upward. The sand under the influence of wind will always roll up along the mountain ridges and sand surfaces, so the sand will not be blown into the spring. The mountains always maintain a shape like a ridge and a blade, which forms the unique and unique scenery of Shaquan.

The fourth day is manual excavation. It is believed that the shape of Crescent Moon Spring is very similar to the half-round crescent moon, which seems to be the result of artificial modification. In addition, there are records of "manholes" in ancient books. Since the name of the well must be the result of human work.
