Abstract

The purpose of this study was to investigate the vegetation structure of Bulguksa around Buddhist Temple Forest in the Gyeongju National Park. To do so, forty-two 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) Pinus densiflora-Pinus koraiensis community, (II) Pinus densiflora community, (III) Pinus densiflora-Acer palmatum community, (IV) Acer palmatum-Pinus densiflora community. The results of vegetation structure analysis were; Bulguksa around Buddhist Temple Forest in the Gyeongju National Park were dominated by Pinus densiflora. IV community, influx of Acer palmatum in Pinus densiflora community, Acer palmatum-Pinus densiflora community are believed to be a change to the community. But, recent spontaneously is growing Quercus variabilis, Quercus aliena, Quercus serrata, Quercus mongolica in understory and shrub layer. Later, it is expected that Pinus densiflora competition. The forest vegetation age of the study area is Pinus densiflora were dominant trees in forest was 30~100 years, old while that of Acer palmatum was 30~36 years old.

경주국립공원 불국사 주변 사찰림을 중심으로 식생구조를 파악하기 위하여 42개의 조사구(단위면적 $100m^2$)를 설치하여 식생조사를 실시하였다. Classification 분석 중 TWINSPAN 기법을 이용하여 군락분리를 시도한 결과, 군락 I은 소나무-잣나무군락, 군락 II는 소나무군락, 군락 III은 소나무-단풍나무군락, 군락 IV는 단풍나무-소나무군락으로 최종 분리되었다. 식생구조 분석결과 경주국립공원 불국사 주변 사찰림은 소나무가 우점하고 있었다. 군락 IV는 소나무 군락에 단풍나무가 유입되면서 단풍나무-소나무군락으로 군락이 변한 것으로 파악되었다. 그러나 최근 자연발생적으로 아교목층과 관목층에 굴참나무, 갈참나무, 졸참나무, 신갈나무가 확산되고 있어 추후 소나무와의 경쟁이 예상된다. 본 조사지역의 산림식생의 임령은 소나무가 우점종인 산림은 30~100년 내외인 것으로 밝혀졌으며, 단풍나무는 30~36년의 수령을 가진 것으로 나타났다.
