Therefore, the name Crescent Moon Spring is not the name of a spring, but a spring in its sand mountain. The spring exists forever in the quicksand. This is the wonder of Crescent Moon Spring, and Crescent Moon Spring is also the famous "Crescent Moon Spring" today! Hehe, I wonder if others see the same thing as me? The nine-story Mogao Grottoes, integrated with the artistic landscape of the Mogao Grottoes in Mingsha Shandong Province, are the "three wonders" connected to the south of Dunhuang City. It has become a tourist destination that people in China and around the world yearn for. Mingsha Mountain is located five kilometers south of the city and is named after the sound of the sand. The mountain is made of quicksand, and the sand is divided into five colors: red, yellow, green, white and black. In the Han Dynasty, it was called Shajiao Mountain, also known as Shensha Mountain, and in the Jin Dynasty it was called Mingsha Mountain. The mountain stretches for more than 40 kilometers from east to west, and is about 20 kilometers wide from north to south. The main peak is 1,715 meters above sea level, with sand ridges connecting each other and winding around. The sand falls with your feet and returns to its original state after passing through. This kind of scenery is really rare in the world. Crescent Moon Spring is surrounded by Mingsha Mountain and is named after its shape resembling a crescent moon. In ancient times, it was called Shajing, also known as Yaoquan. It was once rumored to be Wowa Pool, and was renamed Crescent Moon Spring in the Qing Dynasty. The area is 13.2 acres and the average water depth is 4.2 meters. The water is sweet and clear as a mirror. There are only tens of meters between the quicksand and the spring water. However, despite strong winds, the spring is not covered by quicksand. It is located in the Gobi desert, but the spring water is not turbid or dry up. This unique landform with the emergence of sand springs and the existence of springs and sand is indeed a "wonder in the world". Mingsha Mountain and Crescent Moon Spring are twin sisters in the Gobi desert. "The mountains sound because of their spirits, and the water is beautiful because of their spirits." Visitors will be fascinated whether they take a bird's-eye view from the top of the mountain or take a dip by the spring. It really feels like "the Mingsha Mountain is pleasant and the Crescent Moon Spring washes the heart". In recent years, with the vigorous development of tourism, the local government has adopted various construction and protection measures for the scenic spot to greatly improve its appearance. At the same time, it has also carried out sand therapy, sandboarding, paragliding, skydiving, camel riding and other desert activities. The entertainment projects make tourists full of interest and keep coming in an endless stream. 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 geologists believe that the Crescent Moon Spring is a remnant of the Gudang River channel. It is supplied by underground undercurrents and has survived for thousands of years despite conditions of extreme drought and intense evaporation. The rapid deterioration of the water environment in the past 30 years has raised new questions for people: What is the reason for the decline in the water level of Crescent Spring? 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. This is the result of two sand and dredging operations in 1986 and 1999, and five years of recharge and water replenishment. It attracts 500 people 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. An investigation commissioned by Dunhuang City from the Lanzhou Hydrogeological Engineering Center of the Ministry of Land and Mineral Resources found that the water level of Crescent Spring dropped due to both natural and man-made factors. The latter was the main and most direct cause of the drop in water level of Crescent Spring. (Photography report by Lu Jianrong) What happened to Crescent Moon Spring is a microcosm of Dunhuang’s ecological deterioration. Relevant experts suggest that "major surgery" is needed to protect Crescent Spring: in the long run, strictly controlling groundwater extraction, raising the groundwater level, and maintaining the original dynamic balance of groundwater in the Dunhuang Basin are the fundamental ways to deal with the problem of declining water levels in Crescent Spring. , is also an inevitable choice to maintain the ecological balance of Dunhuang and ensure the sustainable development of social economy. Currently, in order to protect limited water resources, Dunhuang City has completely banned land reclamation, immigration, and well drilling. In terms of cross-basin water diversion, the local government has applied for the "Hajidang" project to divert water from Qinghai, and strives to achieve a quantitative release of water from the upper reaches of the Shule River to Dunhuang every year. Mogao Grottoes, covered with thousands of years of vicissitudes, carries the light of the ancient Buddha, silently watching the sun rise and the moon move in the desert sand. Dunhuang, which gave birth to the Mogao Grottoes, is an oasis city standing in the vast sea of ??sand. It has watched the rise and fall of the Silk Road for thousands of years and witnessed the splendid history of human civilization.In the south of Dunhuang City lies Mingsha Mountain, like a yellow dragon entrenched. On the cliff to the east of Mingsha Mountain is the Mogao Grottoes, and at its heart is the Crescent Moon Spring, the holy spring in the hearts of Dunhuang people. Crescent Moon Spring was born in the embrace of Mingsha Mountain. Over the past 2100 years, the vicissitudes of life have changed. The yellow sand has buried much of the glory of the past, but it has never invaded this clear spring. However, since the 1970s, the water level of Crescent Moon Spring, which had always been stable, has gradually declined. By the 1990s, the water level of Crescent Moon Spring had shrunk in large areas, and the bottom of the spring was clearly visible. People are worried whether the life of Crescent Moon Spring has come to an end.
