Abstract: Aspectral analysis of the population dynamics of Korean pine in the mixed broad-leaved Pinus koraiensis forests was made in this paper. The result shows that there is a marked regularity of periodic fluctuations in the process of natural regeneration of Korean pine. It was discovered that the periodic fluctuation of the annual growth of Korean pine was coincident with that of the natural regeneration process. It indicates that the natural regeneration of the Korean pine population proceeds in the way of periodic wave, which is characterized by the dominant population of a steady community.
