Abstract:: The safe and scientific extraction of cultural relics in archaeological sites can best reveal and preserve the integrity of the unearthed relics as well as the relevant information, so as to create the conditions for scientific protection, complete recovery and further research. By analyzing the new skills and methods applied in the extraction of cultural relics in archaeological sites in recent years such as Uncover and Extract, Set the Box, Banding Method and Freezing Method and new materials adopted in the extraction of cultural relics such as gypsum, polyurethane foam, cyclododecane, menthol and its derivatives, this paper compares the merits and demerits as well as application range of all above with the aim to improve the technologies of historic preservation in archaeological sites.
