Abstract:Daigu landform is the fifth modeling landform after karst landform, Danxia landform, Zhangjiajie landform and Zhangshiyan landform in China. They have greatly aesthetic values and scientific values. But there is still a lack of systematic research and development and utilization. Therefore, the key topics of academic research on Daigu landform in the future is its distribution, morphological characteristics, composition structure, evolution trend, formation mechanism, etc. The research on Daigu landform can reverse current situation of weak mesa research in geomorphology field and enrich the research on continental weathering and terrestrial carbon cycle. Furthermore, it can deepen the understanding of geological and geomorphologic conditions as well as ecological features of Yimeng Mountainous area. Relevant findings will provide scientific support for applying for national geological park and the world natural heritage.
