Abstract

This research aimed at analyzing relationship between spatial distribution of Pinus densiflora, and topographical factors in Seorak and Chiak national park. 100 m grid size was proven to be suitable for analyzing spatial distribution characteristics of Pinus densiflora. Pinus densiflora appeared mainly on 400 m~800 m of elevation, $15^{\circ}{\sim}30^{\circ}$ of slope and 0~2 of TWI. There were no big differences in appearance frequency of Pinus densiflora area by aspect. There were differences in distribution characteristics of Pinus densiflora between below and above 400 m of elevation. There were no big differences in appearance frequency of Pinus densiflora area above 400 m of elevation but a big differences by topographical factors below 400 m of elevation.

본 연구에서는 설악산과 치악산 국립공원에서 소나무 공간분포와 경사, 방위, 고도 등의 지형학적 인자간의 연관성을 분석 하였다. 다양한 격자크기에서 방위에 따른 소나무의 공간분포 분석결과, 100 m 격자크기가 소나무의 공간분포 특성을 설명하기에 적합한 것으로 나타났다. 100 m 격자크기에서 지형인자에 따른 소나무 출현빈도는 고도 400~800 m, 경사 $15^{\circ}{\sim}30^{\circ}$, TWI 0~2에서 각각 가장 높게 분석되었으며, 방위에 따른 차이는 크지 않은 것으로 나타났다. 고도의 계급별로 지형인자에 따른 소나무 출현빈도 차이는 고도가 400 m 이하 일 때 지형인자에 따른 소나무 분포특성이 뚜렷하게 나타났다.
