Abstract

The purpose of this study is to investigate the change and structure of the altitudinal vegetation on the east side of Hallasan National Park, and to accomplish this research, seventeen plots($400m_2$ per zone) were set up along the Seongpanak trail starting from 750m to 1,450m(which was 700m long). These zones, according to the two-way indicator species analysis(TWINSPAN) and ordination analysis(DCA), were divided into six communities: Carpinus tschonoskii-Stryrax japonica community(I), Stryrax japonica-Quercus serrata community(II), Carpinustschonoskii-Q. serrata community(III), Q. mongolica-C tschonoskii community(IV), Acer pseudosieboldianum community(V), and Q. mongolica-Abies koreana community(VI). The findings of my investigation are as follows: the altitudinal vegetation structure of all the investigated zones from 750m to 1,000m above sea level is similar to one another, whereas the same zones from 1,000m to 1,450m above sea level showed dissimilarities among them. That indicates that altitudinal vegetation structure on the east side of Hallasan National Park has changed drastically at the 1,000m areas above sea level, and the forest age of this area is over 50 years.

한라산국립공원 동사면에 위치한 성판악 탐방로를 따라 해발고별로 식생구조와 변화를 파악하기 위하여 해발 750m 에서 1,450m까지 17개 조사구(단위면적 $400m_2$)를 설치하여 조사를 실시하였다. Classification 기법중 하나인 TWINSPAN을 이용하여 군락분리를 시도하고, ordination 기법중 DCA분석을 실시하여 보완한 결과, 군락 I은 개서 어나무-때죽나무군락, 군락 II는 때죽나무-졸참나무군락, 군락 III은 개서어나무-졸참나무군락, 군락 W는 신갈나무-개서어나무군락, 군락 V 는 당단풍나무군락 그리고 군락 W은 신갈나무-구상나무군락의 6개의 군락으로 분리되었다. 해발고별로 종조성을 살펴본 결과 군락의 종조성이 해발 1,000m 이하의 지역에서는 연속적이지만 1,000m 이상의 지역에서는 불연속적으로 나타나 한라산국립공원 동사면지역은 해발 1,000m를 중심으로 식생의 변화가 뚜렷한 특정을 나타내는 것을 알 수 있었다. 본 조사지역의 산림식생의 임령은 연륜분석결과 50여년을 상회하는 것으로 밝혀졌다.
