Difference: it is mostly developed in humid areas, with more precipitation, formed by water erosion and steep appearance.
2. Definition: Ya Dan landform: Due to the abrasion of the wind, the lower part of the hill often suffers from strong erosion and gradually forms a concave shape.
Difference: it is mostly developed in arid areas and formed by wind erosion. Its appearance is mostly small at the bottom and big at the top, and it looks like a mushroom (wind-eroded mushroom).
3. Definition: Karst landform: it is the general name of the surface and underground forms formed by dissolving soluble rocks with water, also known as karst landform.
Difference: It is mostly developed in soluble rock (limestone) area, which is formed by the interaction of dissolution and water erosion, and there are many caves.
4. The Danxia landform in China is widely distributed in tropical and subtropical humid areas, temperate humid-semi-humid areas, semi-arid and arid areas and alpine areas of the Qinghai-Tibet Plateau.
Typical geological landforms of Danxia landform in China are as follows:
Fujian Taining, Wuyishan, Liancheng and Yong 'an;
Zhangye, Gansu (Linze County and Sunan Yugur Autonomous County, Zhangye City)
Malingshan, Xinyi, Jiangsu;
Hunan
Langshan Mountain, Xinning County, Shaoyang, a world natural heritage (located in the southwest of Hunan Province, where Danxia landform developed in youth, Zhuang and old age); Meng Si in Xupu County, Huaihua (located in the west of Hunan Province), Wanfoshan in the northeast of Huaihua Tongdao Dong Autonomous County, Tian Fei Mountain National Geopark in Suxian District, Chenzhou City, Hunan Province, and Bianjiang Scenic Area in Yongxing County, Chenzhou City;

Yongkang, Xinchang and Jianglangshan in Quzhou, Zhejiang (20 10) In the early morning of August 2, the United Nations World Heritage Committee (WHC) unanimously declared "China's Danxia" as the world through the "bundling" of Langshan in Hunan, Danxia Mountain in Guangdong, Chishui Mountain in Guizhou, Longhushan in Jiangxi and Jianglangshan in Quzhou, Zhejiang.

Huoshizhai National Geological (Forest) Park is located in Huoshizhai Township, north of Xiji County15km, east of Liupanshan Mountain140km, and 28km east of Xu Mi Mountain Scenic Area. It is the only scenic spot in Ningxia that has both national geological parks and national forest parks, national AAAA-level tourist attractions and national nature reserves.
It is the highest Danxia landform group in China and is known as the "Colorado Grand Canyon" in China!
The extended data Danxia landform is widely distributed in China. At present, Danxia landform 1005 has been identified, which is distributed in 28 provinces (autonomous regions, municipalities directly under the central government and special administrative regions).
Tropical and subtropical humid areas, temperate humid-semi-humid areas, semi-arid-arid areas and alpine areas of the Qinghai-Tibet Plateau are all distributed. The lowest altitude can be formed in the eastern coastal area, and the highest altitude can be found on the Qinghai-Tibet Plateau above 4000 meters. ..
But relatively concentrated in the southeast, southwest and northwest.
Except China, it is distributed in Central Europe and Australia, among which China is the most widely distributed.
1928, Feng Jinglan and others named the red strata that constitute Danxia Mountain and the corresponding strata in northern Guangdong as "Danxia Layer".
In 1938, Chen first put forward the concept of "Danxia Mountain Terrain".
1939, Chen officially used the taxonomic term "Danxia landform", and the concepts of Danxia stratum and Danxia landform (landform is landform) have been used ever since.
