Shaquan coexistence: the protection of desert wonders

Golden Sand Ring Biwater and Qingquan Yingsha. In the historical and cultural city of the Silk Road, the Mingsha Mountain Crescent Spring Scenic Area attracted countless Chinese and foreign tourists to see his appearance with a unique desert spectacle. Mountain spring is coexisting, and sand and water coexist -why does the desert miracle continue for thousands of years? Entering the Moon -tooth Spring Scenic Spot of Mingshashan City, Dunhuang City, Gansu Province, the reporter will take you to reveal the mysterious veil of the "Mystery of the Millennium" and explore the protection of the coexistence of Shaquan.

Miracle of Desert: Coexist in Shaquan

Dunhuang is both a great drought and a magical desert oasis. Dunhuang is famous for its world cultural heritage Mogao Grottoes and Mingshashan Crescent Spring Scenic Area, and Mingshashan Crescent Spring has always attracted much attention as the "barometer" of Dunhuang's ecological health.

Water and sand coexist, stretch for thousands of years, the sand does not enter the spring, and the water does not turbid. Crescent spring is named after its shape exactly like a crescent moon, and is called "the first spring of the desert". The towering Mingsha Mountain is guarded around Crescent Spring, like a guardian. Against the vast sand dunes, the tranquility of Crescent Spring is unobstructed.

The reeds of the crescent spring are dense into forests, swaying with the wind, rustling, and flourishing at the edge of the water. The most surprising thing is that Mingshashan "blew through the wind, and the same is the same as the old", always maintaining a certain height and stable pyramid shape.

The unique desert wonders attract countless Chinese and foreign tourists every year, and they are eager to see their style. Every tourist who has come has been shocked by this desert miracle, and will also ask questions in unison: how can Shaquan coexist in harmony after thousands of years?

Li Haijiang, director of the Resources Protection Institute of Mingshashan Crescent Spring District, said that Mingshashan Crescent Spring is a unique landscape resources in the world. The magical wind effect is the mystery of Shaquan coexistence.

The monitoring and research by the team of Qujianjun Researchers in Northwest Ecological Environmental Resources Research Institute of the Northwest of the Chinese Academy of Sciences found that the three groups of wind and sand movement of different wind directions have contributed to the formation of Mingsha Mountain. The northeast wind, northwest wind, and southwind interaction, the three groups of winds are not distinguished, and eventually achieved dynamic balance of sand loss. This is the main reason for the long -term harmonious coexistence of Mingsha Mountain Crescent Spring. During the day, the sand was blown down by the wind, and it was blown back to the sand mountain again by the wind. "One up and down" has reached a dynamic balance, so that Crescent Spring has been able to survive peacefully for a long time.

Scientific protection: Miracle stretches

At the beginning of the 21st century, Mingsha Mountain Crescent Spring also encountered risk of moving to the water. The staff monitored and found that the Mingsha Mountain gradually fascinated the crescent spring, manifested as the north of Beisha Mountain and the north of Nansha Mountain, which threatened to the "life safety" of Miruya Spring in Shathan.

To this end, the local government seeks the support of scientific researchers to increase the scientific protection and governance of Crescent Spring. Since 2008, Qu Jianjun has led the team and the scenic management department to cooperate with research, and has established multiple positioning observation sites, and through regional circulation characteristics analysis, local airflow observation, wind and sand activity monitoring, Shashan morphological measurement, wind tunnel test and computer value A variety of scientific means such as simulation finally found the fundamental cause of wind and sand problems, and lifted the danger of being buried by the spring water.

The study of Qujian Corps found that in recent decades, the tall trees and upper winds around Crescent Spring have blocked the northeast wind in the scenic area, weakened the wind speed of the northeast wind, and destroyed the dynamic balance of sand loss of the original three groups of wind directions. The wind and sand natural flow field has been suppressed, resulting in the accumulation of the original stable pyramids and sand dunes, which has changed, causing the deformation and movement of the sandy mountain, and threatened the crescent spring under the Shashan.

Unlike other regions of wind and sand prevention, due to the particularity of geographical location, the premise of coexistence of Mingshashan Crescent Spring is not windproof, but to maintain a dynamic balance of wind under natural conditions. "Generally speaking, windproof and sanding for afforestation, but in the Mingsha Mountain Crescent Spring Scenic Area, because it is to protect the natural desert landscape, not only can we plant tall trees too much, but there must be too high windshields around the surroundings." Qu Jianjun said.

In this regard, they proposed new governance measures. Open the air duct and restore the natural flow field of wind and sand, so as to restore the harmonious coexistence of Mingsha Mountain and Crescent Spring. In recent years, the relevant departments of Dunhuang City have completed the removal of some windshields inside and outside the scenic area and the transformation of the surrounding trees, and the "artificial Gobi" landform has been created in the scenic area. Effect on wind farms and dune forms.

Shi Lin, secretary of the Dunhuang Municipal Party Committee, said that through the cooperation research of science and technology workers and government departments, Dunhuang not only clarified the coexistence mechanism of Shaquan, but also carried out a series of governance projects and achieved obvious results. "As soon as the wind channel was opened, the wind scratched the sand from the crescent spring farther and farther, and the desert wonders of Shaquan were continued."

Multi -party cooperation: blooming shine

At the edge of the crescent spring, the reeds are green; the sand mountain stands, and the yellow sand is magnificent.

In recent years, Crescent Spring has received unprecedented attention and protection. The scenic area has also continuously strengthened cooperation with the Gansu Geological Environment Monitoring Institute, and has increased the dynamic monitoring of crescent spring water resources -has established an information platform for intelligent digital water resources monitoring and management, and improved the water quality monitoring network of surface water and groundwater. The repair of Crescent Spring Spring has been completed, and a series of measures are made to protect and control Crescent Spring by prohibiting a series of measures such as under -mining groundwater in the surrounding area of ​​Crescent Spring, increasing the water time of the party river, and leaking ecological flow.

The implementation of the relevant measures makes Moon Yaquan more "plump and clear". Data provided by the scenic area show that the area of ​​Crescent Spring has expanded from about 12 acres to 24 acres in 2012. Crescent spring water levels rose significantly, remained at about 1.6 meters, and the maximum water depth remained at 2.2 meters. After protection and management, the ecological environment around Crescent Spring is more excellent, showing the joyful scene of the aquatic grass and the shallow background. Mingsha Mountain Crescent Spring also needs to be developed reasonably while being scientifically protected. At the peak tourist season, tourists from all over the world come to Mingsha Mountain Crescent Spring to visit the scene. Experience sand is a must -have entertainment project. In order to meet the needs of tourists and take into account the protection of Shaquan landscapes, the scenic spots will open some of the Mingsha Mountain climbing areas every year to allow Shashan to take turns to rest, but also give tourists with more intimate contact with Mingshashan.
