Abstract

To investigate the vegetation structure of the mountain ridges ranging of Shins un-Bong, this research set up 14 plots($400m^2$) as survey target areas. As a result of the analysis of woody plant cluster, it was classified as two groups-Quercus variabilis-Quercus serrata community and Carpinus tschonoskii community. Quercus variabilis and Quercus serrata was found as a mostly dominant woody plant species in the ridge areas of Shinsun-Bong, while Carpinus tschonoskii were mixed up partly in high altitudes. High negative correlations were shown between Quercus variabilis-Sambucus sieboldiana and relatively high positive correlation were found to exist between Styrax japonicus-Quercus serrata, Sambucus sieboldiana-Rhododendron schlippenbachii, Tilia amurensis, Styrax obassia-Cornus kousa, Rhododendron schlippenbachii-Carpinus laxiflora, Cornus kousa-Tilia amurensis. Species diversity index(H') of investigated groups were ranged from $1.237{\sim}1.497$, and it was relatively high value compared to that of the vegetation structure of other national park.

변산반도 국립공원 신선봉지역의 능선부 식생구조를 파악하고자 능선부에 방형구($400m^2$) 14개를 설정하여 식생을 조사하였다. 식물군집을 분류한 결과 14개 조사구는 굴참나무졸참나무군집, 개서어나무군집의 2개 군집으로 분류되었다. 신선봉지역의 능선부는 대부분 굴참나무와 졸참나무가 우점하고 있었으며 해발고가 높은 일부지역에 개서어나무가 우점하는 임분이 나타나고 있었다. 수종간의 상관관계에서는 굴참나무와 말오줌대는 부의 상관이 인정되었고, 때죽나무와 졸참나무, 말오줌대와 철쭉, 피나무, 쪽동백나무와 산딸나무, 철쭉과 서어나무, 산딸나무와 피나무는 정의 상관이 인정되었다. 조사지의 군집별 종다양성 지수는 $1.237{\sim}l.497$의 범위로 다른 국립공원들의 식생구조에 비하여 다소 높게 나타났다.
