천연경신에 (天然更新) 의한 소나무 유령임분의 (幼齡林分) 구조와 무육방법 (撫育方法) = Structure and Tending Method for Naturally Regenerated Young Pinus Densiflora Sieb . et Zucc . Stands

다국어 초록 (Multilingual Abstract)

This study is performed to consider the fitness of natural regenerating method and tending methods used now by surveying the stand structure and regenerating states of the 9 natural regenerated Pinus densiflora stands in Kangwon province. As a special consideration, it deals with the tending methods on the seedlings of Pinus densiflora and broad-leaved tree(Quercus mongolica) under competition. By the consideration on the number of trees, growing capacity and stand structures of Pinus densiflora stands, it reveals that Pinus densiflora is in the inferior in numbers at the competition to the broad-leaved species, and it could not occupy the stands as the dominant species if the stands were not tended. It is estimated that natural regeneration of Pinus densiflora stands by the clearcutting or seed tree system could not achieved due to the abundance of ground vegetation. Short-term shelter-wood system or strip stand method may be proposed as a successful method of natural regeneration. As the visible tending method for seedlings, the method which apply the mixed forest in group of Pinus densjlora and Querczes mongolica different by the growing capacity and distribution characteristics is better thaw the one which tend the Pinus densiflora only.
