Abstract: The method for reconstructing the disturbance history of Pinus koraiensis mixed forest is developed in this paper basing on the information of release from the data of growth ring collected from more than 300 individual trees. The result indicates that it is a reliable and accurate method for reconstructing disturbance history of forest; such as Pinus koraiensis mixed forest with wind as a main factor of disturbance. Abies nephrolepis; Picea jezoensis and Pinus koraiensis are three useful tree species for analyzing the disturbance history in Pinus koraiensis mixed forest. The ratio of suppression trees in the stand is closely related to the disturbance. Each disturbance makes a large decrease of the ratio of suppression trees, and when no disturbance occurs for long time, the ratio of suppression trees will increase gradually.
