雪嶽山 五色溪谷의 海拔高에 따른 植生分布에 관한 硏究 - 피나무類의 分布를 中心으로

Abstract

This study was conducted to know about the altitudinal distribution of Ti2ia species and to examine the relationship between Tilia species and other species in Osaek valley, Mt. Seolag. This study was conducted during the period from September 18, 1989 to 20 along the course of Osaek Yaksuteo-Taecheonggbon-Seolag Waterfall-Osaek Yaksuteo. The results of this study were as follows: 1) Importance value of the Quercus mongolica was the highest and Tilia amurensis was the second in upper layer, and in middle layer importance value of the Quercus mongolica was the highest. 2) Vertical distribution of Tilia amurensis in Osaek area, Mt. Seolag was ranged from 750m to 1,550m above the sea level. 3) Species diversity of study area was ranged from 0.627 to 1.125. 4) With similarity index value between the altitudes, there was a wide difference between below the elevation of 800m and above the elevation of 1,50Om, and there was a little difference between the elevation of 900m and 1.300m.
