STUDY ON THE RECONSTRUCTION OF DISTURBANCE HISTORY OF PINUS KORAIENSIS MIXED FOREST IN CHANGBAL MOUNTAIN
长白山红松混交林干扰历史的重构研究

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 reconstruct-ing disturbance history of forest,such as Pinus koraicnsis mixed forest with wind as a main factor of disturbance. A bies nephrolepis,Picea jezoensis and Pinus koraientis are three useful tree species for analyzing the disturbance hi-story in Pinus koraicnsis 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.
