中文摘要：

在中国丹霞地貌走向世界，开始一个新的发展阶段的时候，回顾并评述国内外红层和丹霞地貌的研究进展十分必要。国内在该领域的研究长期集中在红层特性、工程地质、丹霞地貌特征及发育的基本问题等方面，但对红层的地质和地貌融合研究不足，对不同红层的岩性差异及其在外动力条件下的地貌表现和地貌发育过程缺乏深度研究；国外还没有红层地貌和丹霞地貌的专门研究，学者们主要关注红层形成的地质背景，有关红层地貌的研究多分散在砂岩地貌中，但其在微观、定量、实验研究方面值得借鉴。本文认为当前有关红层和丹霞地貌的研究大多为单因子研究，缺乏系统的思想方法，各学科研究存在多张皮的问题。提出应明确红层和丹霞地貌的学科归属，深化基础研究，加强各学科之间的融合，并推动国际交流和对比研究。

英文摘要：

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.
