Abstract

The purpose of this study was to investigate the vegetation structure of Daphniphyllum macropodum community in the Geumseon Valley area of Naejangsan National Park. To do so, thirty-seven plots($100m^2$) were set up and surveyed. The surveyed plots were divided into four groups according to the analysis of classification by TWINSPAN; (I)Carpinus laxiflora community (II)Carpinus laxiflora community (III)Deciduous Broad-leaved community and (IV)Zelkova serrata community. The results of vegetation structure analysis were; Daphniphyllum macropodum did not appeared in the canopy later but in understory and shrub layer. Even though Daphniphyllum macropodum will not be dominant species in the canopy later, but it was expected that Daphniphyllum macropodum will be major species in understory and shrub layer. The expected age of forest of the Geumseon Valley where Carpinus laxiflora and Zelkova serrata were dominant trees in canopy layer, was about 50 years old while that of Daphniphyllum macropodum in understory layer was 20 years old.

내장산국립공원 금선계곡을 중심으로 식생구조를 파악하여 굴거리나무의 생태적 특성을 밝히고자 37개의 조사구(단위면적 $100m^2$)를 설치하여 조사를 실시하였다. Classification분석 중 TWINSPAN기법을 이용하여 군락분리를 시도한 결과, 군락 I과 군락 II는 서어나무군락, 군락 III은 낙엽활엽수군락, 군락 IV는 느티나무군락으로 최종 분리되었다. 식생구조 분석결과 내장산국립공원 내의 금선계곡지역의 굴거리나무는 교목층에서는 출현하지 않은 반면 아교목층과 관목층에서 주로 관찰되었으며, 추후에는 굴거리나무가 점차 세력을 확장하여 아교목층 및 관목층에서 주요종이 될 것으로 판단된다. 임령분석결과 금선계곡부에서 서어나무와 느티나무가 우점종인 산림은 약 50여년 내외인 것으로 밝혀졌으며, 굴거리나무는 20여년의 수령을 가진 것으로 나타났다.
