A review of the research on red beds and Danxia landform

In the context that China Danxia landform went into the world and began the research of a new phase,it is necessary to make a review on the research progress of red beds and Danxia landform in and outside China.It is revealed that the domestic study was focused on the characteristics of red beds,engineering geology,features of Danxia landform and the basic problems of development.In general,in China there were no integrated studies of red beds concerning the field of geology and geomorphology,and the differences between lithologic characteristics of red beds and their related geomorphic development processes under the influence of exogenetic force were not well understood.However,research outside China were limited in the field of geology,and relevant studies of red beds and Danxia landform were conducted in the field of sandstone landform,with a microscopic,quantitative and experimental analysis.This paper suggests that most of the existing studies on red beds and Danxia landform were focused on single factor,and lack of subject system,and the integration of related subjects was also insufficient.Then,a new agenda for the future research was put forward,in which a clear discipline classification of red beds and Danxia landform and further basic research should be made,and the integration of related subjects,international communication and the global comparative research should also be strengthened.
