When it comes to deserts, people's first impression is:Desolate, full of yellow sand, lifelessThe view. As everyone knows, in the desert, there are also green miracles, which are collectively calledOasis, in the middle of the desertIt's like a wonderland
It was a corner of the desert, full of green aquatic plants, and full of life. This touch of greenery often gives hope to people and creatures in the desert environment.
Then you know that in the yellow sand of the sky, thisA touch of greenHow there is existenceToughIs it?
In the desert want to form an oasis,An abundant and uninterrupted supply of water is a must。Usually, there are them in the desertUnderground riverThe existence of these underground rivers is mostly in the vicinityMountains
In winter, these mountains are covered with a thick layer of snow, and in summer, when the snow melts, the snow water flows down the cracks in the mountains to the low-lying areas, hiding in the sandy soilAfter years of erosion and precipitation, a dark river was formed, and finally it became an oasis.
However, the Oasis did not last long.
It seems to be exceptional in the middle of the vast desertSmallAfter all, the petite body can't resist the erosion of the wind and sandIt was swallowed up like water.
Sahara DesertIt is known as the largest desert in the world;However, the Sahara Desert is thereAncient timesIt was once full of lifeOasis, and now it becomesExpansity and desolation coexistplace.
Now faced with the serious problem of desertification, ZengSomeone, even generations, has taken root in the desert, just for thatA touch of green；Sand control peopleSun has the stateIt was one of them who spent twenty years and did not hesitate to exhaust tens of millions of family assetsJust to turn 10,000 acres of yellow sand into an oasis of 10,000 acres.
Of course, there are many, many more such cases. One can imagine how difficult it is for the oasis to survive in the desert.
However, what is unexpected is that the crescent moon spring in Mingsha Mountain in Dunhuang is an "accident".
Mingsha MountainYesThe southern part of Dunhuang in GansuA scenic spot, the reason for its fame is even more becauseCrescent SpringExistence;Crescent Spring, is a magical place, to:The thousand-year-old spring water does not dry up and is famous all over the world
Mingsha Mountain is".Flowing sand"Formed by a hill, and the crescent spring was coveredSurrounded by sand mountainsLike a crescent moon, and the crescent spring water is crystal clear,Like a mirror, is a placeA natural oasis
Throughout the ages, there have always been good stories at the crescent spring, such as ".Mountains and springs are intertwined, and sand and water are accompaniedMingsha Mountain and Crescent Spring seem to be partners who will never abandon each other, and they have been with each other to this day.
Deserts and oases, singing sand and crescent moons, are also known as "a must in the good scenery outside the Saiwai".
The reason why the oasis exists must be fed by a steady stream of waterSo the water source of the crescent moon spring comes from?
The crescent moon spring in history never seems to dry up, and that's because of itThere's an ancient river buried beneath the groundIt is precisely because of the existence of this dark river that the crescent spring is constantly fed, so as to ensure that the water of the crescent spring will never be exhausted.
Party RiverYesShule Rivera tributary. The Dang River is only far from the Crescent Springkilometers, although the distance is very close, the Dang River does not flow directly into the crescent spring from the ground, but when the water of the Dang River is higher than the crescent spring, it will be causedThe gravitational action of the dropThe water seeps into the ground and flows into the dark river beneath the Crescent Spring.
The abundance of water in the Dang River is partly dependentGlacier meltingAfter the snow water is replenished, plusRainwaterThe replenishment can be said to be endless, and the crescent spring also relies on the abundant water source of the Dang River, and has not dried up for thousands of years.
As mentioned above, the Sahara Desert was formerly known as an oasis, and such a large oasis has been desertified, so you can imagine how those countless small oases should exist.
So why hasn't the crescent spring been desertified?
As we all know, the crescent moon spring isThe Silk RoadThe pearl of the opening;SoThe ancient kingdom of LoulanThe same pearls of the Silk Road have disappeared into the desertWhy does Crescent Moon Spring still exist?
The desert swallows up everythingThe sand and dust kicked up by the strong wind covered it, Gansu Dunhuang area perennial to moreSouthwestwithNorthwestWind dominates,Wind directionEncounteredNatural locationMaybe perfectlyAvoidthe hazards of sand and dust.
WhenWest windThe surrounding area of the crescent spring is humid all year round, and there are plants and trees growing, the nearby sand slopes are relatively gentle, and the desert in the distance is surrounded by high mountains, and the sand and dust are naturally not too high.
WhenSoutherly windThere is a tall tree and building on the south side of the Crescent Spring, and the wind and sand will not be blown into the Crescent Spring.
WhenNorth windWhen the sand flies over the high ground, there is just a glide in the air, and it flies directly over the crescent spring and falls directly to the opposite shore on the north side. The stronger the wind blows, the faster the sand grains become, and it is never far away from the crescent spring.
This creates a phenomenon in which a strong wind flies over the upper part of the crescent springNot a drop of spring water is taken away, and not a single grain of dust falls in. Tourists who have been to the Crescent Spring can't help but sigh at this sceneThe wind does not blow, the sand does not accumulate, and it is spotless.
Not only that, but the crescent moon spring even encountered oneStormy windsThe water of its springs will not become cloudy because of this, and it will always beOut of the mud without staining
And all this withParty River and unique geographyLocation has a lot to do with itIt may be said that it is the magic of nature that has given it to people.
It may be that nature has given too much, just like spring, summer, autumn and winter, as colorful and countless;People fromThe first aweBegin to becomeConfidenceOriginally, people just wanted to make the products given by nature last longerBut some of them seem to have forgotten their original intentions.
Maybe you don't believe it, but it's a fact.
Today's crescent moon spring has long been alreadyThis is not what it used to beThe crescent spring water is no longer what it used to be."Spring waterRather, ratherManual replenishmentof water.
Back in70s of the last centuryIn order to irrigate the needs of the locals, part of the water of the crescent spring is pumped;Coupled with the fact that later as a tourist attraction, man-made commercialization and the emergence of a large number of pollution sources, will be localThe ecological balance is broken, thus the crescent spring is affected.
The original natural beauty of Crescent Spring has almost disappeared, and people have gradually realized the seriousness of the problem.
It is said that in order to restore the original pure and beautiful appearance of the crescent spring, the local ** did not hesitateIt cost 4 billion yuan to continue his life, that is", ".Artificial infusion"., the crescent spring was able to maintain the status quo.
What will the crescent moon spring look like after that remains to be seen.
If you think about it, the current situation of Crescent Spring seems to be related to peopleIt is impossible to dissociate the relationshipNowadays, it costs money to sustain life or it is nature for peoplePunishment
In fact, it is not only the natural scenic spot of Crescent Spring that is facing such a problem, but also many distinctive places nowadaysThere is no shortage of people who are exploiting the charm of nature to extract profits.
Perhaps the "travelers who come here" from Li Bai's poems will really "have nowhere to travel".
