Dunhuang UNESCO Global Geopark is located in the City of Dunhuang, Gansu Province, People’s Republic of China. Located in the Anxi-Dunhuang Graben Basin, east of the Tarim plate, Dunhuang UNESCO Global Geopark is rich in geoheritage of great scientific value, as well as significant value in geo-education and geotourism. The most representative geoheritage is the Yardang-Desert-Gobi landforms, which constitute typical landforms in the extremely arid region of China and the Mogao Grottoes, a World Heritage Site, which were excavated in the Quaternary strata and perfectly embody the combination of geoheritage and culture. Among them, the Yardang landform is globally rare for its dense distribution, graceful shapes, large quantities and obvious changes in trend and complicated formation, which makes it important in studying formation and regional environmental evolution.
