Archaeological digitization is a process of recording，storing and delivering a huge number of graphics，images，texts，audio，video，spatial location and other information which contained in various archaeological materials by using various digital application technologies. These methods have been widely used in the field of archaeology. Based on the comprehension of the policy and industry demands，this paper expounds the three stages of archaeological digitalization development，namely technology research、maturation and popularization，and introduces its achievements from the perspective of application. Finally，it predicts that archaeological digitization will develop steadily and rapidly in several directions，including the centralized management of archaeological information resources，the integration of archaeological affairs and the intelligent analysis on archaeological research.
