Danxia landform is a special continental red beds landform which is characterized by red scarp slope. Danxia landform as a new rock landform types is named by Chinese geologists. A great amount of work has already been done by Chinese scholars on Danxia geomorphology more than 80 years of history. In this paper,we make a brief overview on the field of China Danxia geomorphological study,including the definition of Danxia landform, types and distribution of Danxia landform in China,internal and external forces of landform processes,Danxia land-scapes tourism development and its protection aspects. The red layers of activation Diwa areas is primarily consist of sandstone,conglomerate,sandy conglomerate,mudstone,clastic rock material. In China,Diwa areas deposition had already begun since the last Triassic,the Jurassic and Cretaceous period is strongest. With the tectonic uplif-ting,occurred tilting,folding,fracture,and produce a series of joints,these within basins become into outflow ero-sion areas. Under water and wind erosion,denudation and collapse,weathering,biological,wave action,artificial role and other external force,different Danxia landform types development under the control of the different roles. Danxia landscapes is characterized by its red and escarpment. By the end of 2012,Total 1 003 Danxia landscape sites hand been discovered in 28 provinces in China. Eighty percent of them are distributed in the crust uplifting red basins formed in Mesozoic and Cenozoic fault basins. Altitude from sea level to 5 000 meters,from semi-arid and arid areas to semi-humid and moist zones,fourteen climatic regions have Danxia landform distribution. It is es-timated about one fifth of national scenic spots is Danxia landscapes in China. Danxia landform is one of natural rock scenery. They are human’s wealth and the earth heritage. Some endangered and famous Danxia scenic sites must be protected.
