The development of Danxia Landform research in China experienced three historic stages, i.e. initial establishment, taking shape and expanding since the concept 'Danxia Landform' raised by Prof. Chen Guoda in 1939. As a new branch of geomorphology, Danxia geomorphology research is now stepping its ripe stage. In the 1990s, the search enters into an unprecedented grand occasion at the prompting of tourism exploit.展开更多
