[Central Media to see Gansu] Chinese Story | Shaquan "Repulse" Dunhuang Eternal Legend

"Onehhhhhhhhhhhhhh is embedded in Sha Mountain. For thousands of years, sand has not been concealed, and Shaquan coexist." As early as the Eastern Han Dynasty, historical materials recorded the strange landscape of Dunhuang City, Gansu Province. Why does the miracle of Shaquan coexisting for thousands of years? A few days ago, the reporter walked into the Makiya Spring Scenic Spot of Mingshashan City, Dunhuang City to explore the mystery of the ages.

Why do Shaquan coexist in harmony?

The historical and cultural city on the Silk Road is close to the Kumtag Desert and is a magical desert oasis. Here is famous for its world cultural heritage Dunhuang Mogao Grottoes and Mingshashan Crescent Spring Scenic Area. Among them, Mingshashan Crescent Spring has always attracted much attention as the "barometer" of Dunhuang's ecological environment.

As water and fire are incompatible, water and sand seem to be unable to coexist. But such "accidents" really exist in Mingsha Mountain Crescent Spring Scenic Area and lasted for thousands of years.

Crescent spring is named after its shape. The reeds of the spring are dense into forests, swaying with the wind, rustling, and flourishing at the water. The majestic Mingsha Mountain is guarded around Crescent Spring, like a guardian. "After the wind blows, it is like the old", Mingsha Mountain always maintains a certain height and stable pyramid shape.

Water and sand coexist, stretch for thousands of years, the sand does not enter the spring, and the water does not turbid.

This peculiar landscape attracted countless Chinese and foreign tourists to come to Dunhuang not far away to see Fang Rong. People often ask: "Why do Shaquan coexist in harmony?"

According to Li Haijiang, director of the Resources Protection Institute of Mingshashan Crescent Spring District, the magical wind effect is exactly the mystery of Shaquan coexistence.

The monitoring of the team of Qujianjun, a researcher at the 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 contributed to the formation of Mingsha Mountain. The northeast wind, northwest wind and southwind interaction, the three winds of the three are not divided into the 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 safe for a long time.

Scientific sand control protection beautiful landscape

However, in the early 21st century, local staff had monitored and found that Mingsha Mountain gradually fascinated the crescent spring, manifested as the north of Beisha Mountain, and the Nansha Mountain moved north, which seriously threatened the "life safety" of Crescent Spring.

In this regard, the local government has increased the protection of Crescent Spring. Since 2008, it has strengthened cooperation with the Qujian Legion, carried out research on Shaquan coexistence mechanisms, and carried out strict protection and governance.

Qu Jianjun, the national anti -Sands and Sands, led the team and the scenic management department to cooperate with the research department. They have established a number of intelligent digital positioning observation sites, and finally found a solution strategy through various scientific means such as regional circulation characteristics, wind and sand activity, and the shape monitoring of Shashan morphological monitoring.

The 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, destroyed the dynamic balance of the sand loss of the original three groups of wind directions, suppressed the inhibitory The wind and sand naturally flow field, which has caused the shape of the pyramids and dunes that was originally stable and good, which has accumulated changes day by day, causing the deformation and movement of Shashan, threatening the crescent spring under the sand mountain.

According to Qu Jianjun, unlike other regions of wind and sand prevention ideas, due to the particularity of geographical location, the prerequisite for the protection of Shaquan coexistence is not windproof, but to maintain a dynamic balance of wind under natural conditions.

In this regard, they put forward targeted governance suggestions. Open the channel of wind and restore the natural flow 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. The transformation of the surrounding trees, the tall trees that block the wind in the northwest wind and the northwest wind ventilation channel have also been cut.

Shi Lin, secretary of the Dunhuang Municipal Party Committee, believes 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 significant results.

Desert wonder blooms

In recent years, Crescent Spring has received unprecedented attention and protection. The scenic area has also continuously strengthened cooperation with the Gansu Provincial Geological Environment Monitoring Institute, strengthened dynamic monitoring of crescent spring water resources, and successively established intelligent digital water resources monitoring and management information platforms, improved the water quality monitoring network of surface water and groundwater, and strictly ordered the order. Forbidden groundwater in the area around Crescent Spring.

The implementation of protection and governance measures makes Moonlon more "plump and clear". Data show that the water area of ​​Crescent Spring has expanded from about 12 acres to 24 acres in 2012. Crescent spring water levels have risen significantly, so far remained at about 1.6 meters, and the maximum water depth remained at 2.2 meters. After protection and governance, the ecological environment around Crescent Spring tends to be excellent.

Golden Sand Ring Biwater and Qingquan Yingsha. The desert wonders need 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 sliding is a necessary entertainment project. In order to meet the needs of tourists and take into account the protection of Mingshashan Crescent Spring, the scenic area will open some of the Mingshashan climbing areas every year to allow Shashan to take turns to rest.

Shaquan "rejoicing", this millennium "Chinese business card" is displayed in front of the world with a more beautiful face.
