Daocheng County, located in the southern part of the Yidun island arc belt, has rich types of geological relics, huge vertical elevation difference, three- dimensional climate and unique landforms, which have created many magnificent natural landscapes. It is known as “the last pure land on the blue Mercury”. However, it has never comprehensively and systematically sorted out the geological relics resources in Daocheng area. We have classified and summarized the geological relics in Daocheng, clarified their distribution characteristics and scientific connotation, and put forward corresponding protection and utilization suggestions, laying a scientific foundation for the development of local tourism economy.Methods: Through the detailed investigation of geological relics and the data combing of the previous investigation work, according to the “Geological Relics Investigation Specification” (DZ/T0303- 2017), the geological relics in the study area are classified and summarized, and their types and distribution characteristics are clarified. Excavate and enhance its scientific connotation, and from the perspective of tourism geology, put forward suggestions for protection and utilization, and provide ideas for the construction of the Aden Geopark in Daocheng and the protection and utilization of geological relics. Results: There are abundant types of geological relics in Daocheng area, which are divided into 3 groups, 8 types and 17 subtypes, including basic geology, geomorphological landscape and geological disasters, with a total of 194 sites. Among them, there are 171 geomorphological landscapes, accounting for 88. 14% of the total number of geological relics, accounting for the absolute dominant position; there are 69 water landforms in the class, accounting for 35. 57% of the total. Among the subtypes, only the ancient glacial relics subtypes≥50, the largest number. These 194 geological relics are intrinsically linked in genesis and space, and can be summarized as 15 important geological relics concentration areas.Conclusions:① The geological relics of Daocheng are controlled by the influence of strata and structures, characterized by various geomorphological landscapes, showing “linear” and “agglomeration” distribution; ② due to the influence of the “north—south high middle low” geomorphological pattern, the distribution of geological relics is obviously controlled by altitude, and each has its own characteristics. All kinds of canyon forms and glacier landforms are distributed. Based on the types, characteristics and distribution of the geological relics landscape in Daocheng area, some suggestions for protection and utilization are put forward: ① Strengthen the integration of geological culture; ② the rational planning of geological tourism products; ③ innovate the way of popular science propaganda ; ④ pay attention to all kinds of “Geology+” brand creation.
