The country has built two holy pools near Crescent Spring. Every year, more than 6 million cubic meters of water is lent from the reservoir and injected into Crescent Spring. It can be said that Dunhuang City is making every effort to rescue the Crescent Moon Spring, and has also implemented a policy of prohibiting land reclamation, including drilling wells, and allowing local residents to emigrate. It is conducting all-round management and injecting water into the Crescent Moon Spring in a planned way.
In fact, according to the relevant national data, during the period from 1995 to 20 10, the nearby Mingsha Mountain, like a crescent spring, was directly close to 8~ 10 meter, which directly reduced the area of the crescent spring at that time by nearly 7% and even threatened to be swallowed up. According to historical records, Crescent Moon Spring is a very famous tourist destination in Han Dynasty, with unique architecture and lush trees beside it. Later, from the 20th century to the mid-1970s, due to local pumping irrigation and the destruction of various plants, soil erosion became more serious, which led to the rapid decline of the groundwater level in Dunhuang, and the decline of the water level in Yueya Spring was even more dramatic. At that time, there was little water, and the crescent spring even formed two Koizumi.
After a long period of construction and a variety of planned water replenishment, a large part of the environment of Crescent Spring has gradually recovered to the previous trend, and the current water depth can be maintained at around 1m 7. Whether it can be preserved for a long time is still a question. After all, it is human intervention, and it will certainly not last long. Many ancient buildings in China will certainly not remain intact if they were not built by later generations, so people will certainly not interfere with their preservation.
