Over the past few years, many geoheritage protection work has been carried out in the Mount Mingshashan and Crescent Moon-shaped Spring in Dunhuang UGGp, mainly including:

1. Strengthening cooperation and exchanges with scientific research institutes in the protection of geoheritage

First, we have reinforced connections with the China Urban Construction Design & Research Institute. Construction projects in the UGGp were strictly carried out according to the requirements of the “Master Plan” and “Detailed Plan” of the UGGp. Secondly, we  strengthened our contact with the CAREERI,CAS and set up 10 instruments of measuring wind-sand in Mount Mingshashan, sampled and monitored the changes of wind-sand in Crescent Moon-shaped Spring every year. We have completed the “Final Report on Circulation Characteristics of Mount Mingshashan and Crescent Moon-shaped Spring and Dynamic Change of Sand Mountain and Sand Control Planning”, and the“ Report on Dynamic Change of Sand Mountain in Mount Mingshashan and Crescent Moon-shaped Spring”, which will guide UGGp to dredge air duct according to the change of wind direction. Thirdly, we have cooperated with Gansu Geological Environment Monitoring Institute, analyzed the water level changes and provided guidance for groundwater protection of Crescent Moon-shaped Spring.

2. Continuous air duct dredging

According to the observation data and research results of the CAREERI,CAS, the management office continued to dredge the air ducts in the UGGp from 2015 to 2018, with a total investment of about 2.2 million yuan. In 2015 and 2017, all kinds of trees were removed, which would affect the northeast wind and northwest wind .In 2017, according to the wind tunnel experiment plan of the CAREERI,CAS, 49 trees in the east of Yuequan Pavilion were removed, the west chamber of Yuequan Pavilion was demolished, and reinforced the top gravel coverage of the Tiebeiyu Pool and its fence. The wind tunnel in the geopark was effectively dredged, and the situation was effectively alleviated, that the northward movement of Nansha mountain and the central uplift of the south slope of Beisha mountain.

The air duct of the geopark is effectively dredged, and the situations of the northward movement of Nanshan Mountain of Crescent Moon-shaped Spring and the uplift of the middle part of the southern slope of the Beisha mountain are effectively relieved.

3. Enhance the environmental renovation and tomb relocation in the East Gobi

Firstly, we improved the environment of the East Gobi. In 2015, the area of 0.5 km2 was renovated in the East Gobi. The camel enclosure and firewood and grass dump in the East Gobi were removed, sand and stone pits and garbage dumps were landfilled and cleaned, and the original Gobi style was restored by water sprinkling, compaction and gravel covering. At the same time, water supply, electricity, wooden nursing houses and ecological toilets were provided.

4. Installing mountain fence in Mount Mingshashan

With the warming up of all kinds of outdoor tourism, tourists enter the sand mountain to explore, causing serious damage to the Mount Mingshashan and sand dunes. In order to protect Mount Mingshashan and Crescent Moon-shaped Spring, the management office implemented a 21.7 km mountain fence construction project in 2016. The construction of fencing effectively protected the resources of Mount Mingshashan.

5. Strengthen the monitoring of Crescent Moon-shaped Spring and surrounding mountains

We measured the water seepage field A, C and the observation wells around the Crescent Moon-shaped Spring every day and every week. We have accurate data and detailed records as required, accumulating a lot of basic data to analyze the water level change of Crescent Moon-shaped Spring. At the same time, we hired professional surveyors to regularly measure the sand mountain around Crescent Moon-shaped Spring, and make the analysis report of mountain changes.

6. Enhance law enforcement and supervision

Firstly, we set up management posts at key spots, implemented full-time management and delimited tourist activity areas in order to effectively protect the landscape of sand ridges and sand slopes. We strengthened the inspection and protection of fences in UGGp, and prohibited the illegal mining of sand and stones, private construction and overturning of fences. Secondly, to solve the problems of illegal construction around the UGGp, in 2017, the administrative department jointly enforced the law with the relevant departments of Yueyaquan Town, Public Security, Land and Resources Bureau, Industry and Commerce. Thirdly, many departments were united to rectify and standardize camping and exploration projects along the mountains.

7. Resources protection

Carrying out the law popularization. We interpreted the relevant policies and regulations to the local people through household publicity and distributing leaflets to the surrounding farm inns and farmers. And  the official website of UGGp, WeChat and various media were also used to publicize relevant policies. The behavior of destructing geoheritage has been punished, and the tourism market was effectively standardized. Theme publicity is carried out four times a year and more than 20,000 publicity materials are distributed.
