Is it finished? Will it disappear? How to rescue? This mystery, through the raw ore.
The Ministry also entrusted Lanzhou Hydrogeology Center to organize some experts to conduct investigation and study, and soon
Finally solved the previous mystery. Experts believe that it is shrinking and adopting high technology.
Rescue is expected to be controlled early next year to avoid extinction.
Yueya Spring is located in Mingsha Mountain, 5 kilometers south of Dunhuang City, Gansu Province.
Crescent Moon Spring and Mingsha Mountain, both known as the two natural landscapes in Dunhuang, have been attracting people for many years.
Countless Chinese and foreign tourists came to watch. Crescent spring originates from its crescent shape.
Name. In the past, there were many explanations for its genesis, such as "fault spring layer" and "oxbow lake"
But I haven't done any special investigation and study. The former Ministry of Geology and Mineral Resources invited in July last year.
Many famous experts, including many academicians of China Academy of Engineering, have made progress in Crescent Spring.
"Consultation", after more than a year of ground investigation and geophysical work, finally
Yu discovered the cause of crescent spring. It turns out that this is the remnant lake of an ancient river, because of the land.
The undercurrent is exposed here, forming many springs and gathering into pools. What's strange about it
Surrounded by sand mountains on three sides, it has not been destroyed since ancient times.
According to the person in charge of the project, after exploration, Crescent Moon Spring is underground by Dang River.
Shallow groundwater recharge is formed after water leakage. The crescent spring area is the ancient of the past
River, it has a unique and smooth supply, runoff, discharge channels, even if
In high temperature climate, Crescent Moon Spring has never dried up because of a large amount of evaporation of spring water.
Dry up; Coupled with the crescent moon spring surrounded by mountains on three sides and the open special terrain on one side,
Crescent spring has not been buried by a large number of sandstorms.
But experts also pointed out that this historical wonder is in danger of disappearing.
According to the survey, in 1950s, the water area of Yueya Spring reached 14652 square meters, with an average water volume.
5 meters deep, 7 meters deep; By1September, 1998, the water area of Crescent Spring was only
5379 square meters, the average water depth 1.2 meters, and the deepest point is only 2 meters. expert
Scientists believe that at this rate of contraction, Crescent Moon Spring will cease to exist within three years. that
The main reason is that a large number of groundwater are exploited locally.
According to this situation, Gansu Province and Dunhuang Municipal Government decided to adopt experts.
It is suggested that the relevant geological and technical departments take high-tech measures to save the ages.
The beautiful crescent moon spring.
