Abstract: The Lingshan Island is rich in geological relic resources with high value for scientific research and tourism development. Previous studies in this area are mainly focused on geology, and little is paid to the development of geological relics. A systematic comprehensive survey has been made this time from the viewpoint of geological relics and geological tourism resources. More than 30 geological relics are identified, and grouped into 3 large categories, 9 categories and 10 subcategories. The evaluation and classification of geological relics are carried out through comparative analysis and expert evaluation. Based on the detailed introduction of the types and characteristics of the geological relics, this paper puts forward some suggestions from the perspective of geological science popularization and tourism development, in order to improve the management of geological relics for sustainable development of island economy.
