Abstract: Primary Korean pine forests are uneven-aged and complex in the area of the xiao Xing An Hountain. The stocking in the main story amounts to more than 80% of the volume. The forest mainly consists of three or four-age-class trees, the attribute is that the main part in the stand is formed by the trees whose ages belong to the average age-class, while the trees whose age-class is one age-class higher or lower than the average age-class is the second main part. In the main stand, the Korean pine trees at the ages of Ⅸ Ⅹ Ⅺ age-class (161—220 year) are the most widely distributed and amount to 75%.To protect the existing primary Korean pine forest and increse their quality, intensive management must be treated in the survived primary Korean pine forest, cleaning-cutting and repair-planting should only be used in protection forest management zone. In the management zone selection cutting must be used.
