Based on the matrix model, the dynamic growth of broad - leaved Korean pine forest in Changbai Mountain was simulated by using nonlinear dynamic model based on the data of diameter growth, plantar growth and withering, and the changes of stand diameter under different cutting intensities The effects of different harvesting intensity on annual growth, annual harvest and years of recovery were analyzed. The results show that the nonlinear dynamic model has the advantages of rigorous structure and high precision in simulating stand growth. The model is extended to the logging forest, which provides a scientific basis for the scientific management of the broad-leaved Korean pine forest and the development of a reasonable harvesting plan.
