Abstract

A vegetation structure by attitudinal changes from Jeongryongchi to Gogiri section of Baekdudaegan were investigated by sample plots(nine 500$m^2$). Using TWINSPAN and DCA techniques, vegetation structure was analyzed. In the results from the analysis of both techniques, Quercus mongolica is dominant species and attitudinal zonations were divided into 2 groups such as above 900m area and lower one by subspecies in subtree and shrub layers. Similarity index analyses of elevational ranges showed discontinuities between above and lower elevation area. In the analysis of species diversity, there was no significant difference due to altitude.

백두대간 정령치~고기리 구간에 대해 해발고별 식생변화를 살펴보기 위하여 해발고 l00m마다 10m X 10m(l00$m^2$)의 조사구 5개씩 총 45개 조사구를 9개 지점에 설치하여 조사하였다. 군락의 분리를 위해 TWINSPAN과 DCA기법을 이용하였으며, 그 결과 정령치-고기리 구간은 교목층에서 신갈나무가 우점종인것.으로 밝혀졌으나 해발 900m를 기점으로 아교목층 및 관목층의 부수종을 중심으로 식생구조에 차이가 있는 것으로 밝혀졌다. 유사도지수에서도 유사한 결과를 나타내었으나 종다양도 분석에서는 해발고간 차이가 없었다.
