Abstract

The purpose of this study is to understand the vegetation structure and ecological characteristics of the coastal forest Pinus thunbergii community in Busan Metropolitan City (BMC) and to establish reference information for the management of the coastal forest in BMC in the future. We set up 97 plots with an area of $100m^2$ each for the analysis and investigation of the vegetation characteristics. The analysis using the TWINSPAN and DCA techniques found seven community groups: Pinus thunbergii-Quercus aliena community, Pinus thunbergii-Eurya japonica(1) community, Pinus thunbergii-Eurya japonica(2) community, Pinus thunbergii-Quercus serrata community, Pinus thunbergii-Camellia japonica(1) community, Pinus thunbergii-Camellia japonica(2) community, and Pinus thunbergii-Eurya japonica-Camellia japonica community. According to the analysis of vegetation structure, Pinus thunbergii was a main dominant species at the canopy layer in all sites while Eurya japonica and Camellia japonica were dominant species at the understory layer. Pinus thunbergii-Quercus serrata community is predicted in the forest succession because of the competition between Pinus thunbergii and Quercus serrata in the canopy layer and the understory layer. As such, it is necessary to observe changes by continually monitoring this community. Tree species with strong salinity tolerance, including Pinus thunbergii, have formed community groups because of the environmental characteristics of coastal forests, strong with salinity tolerance species are forming community groups. Therefore, all community groups except for the Pinus thunbergii-Quercus serrata community will maintain the current vegetation structure unless drastic environmental changes occur.

본 연구는 부산광역시 해안림 곰솔군락의 식생구조 및 생태적 특성을 파악하여 해안림의 식생구조를 파악하고 향후 부산광역시 해안림 관리방안을 위한 기초자료를 구축하고자 수행하였다. 부산광역시 해안림 지역에 $100m^2$ 크기의 조사구 97개를 설치하여 조사 분석하였다. TWINSPAN과 DAC기법을 사용하여 군락을 분리한 결과, 곰솔-졸참나무 군락, 곰솔-사스레피나무(1)군락, 곰솔-사스레피나무(2)군락, 곰솔-갈참나무군락, 곰솔-동백나무(1)군락, 곰솔-동백나무(2)군락, 곰솔-사스레피나무-동백나무군락으로 분리되었다. 조사결과 부산광역시 해안림 곰솔군락의 교목층에서는 곰솔이 주요 우점종으로 나타났으며, 하층식생에서 사스레피나무와 동백나무가 우점하였다. 곰솔-졸참나무군락에서 졸참나무가 일부 교목층과 아교목층에서 곰솔과 경쟁관계를 이루고 있으며 변화를 살피기 위해서는 지속적인 모니터링이 필요할 것이다. 해안림의 환경 특성상 곰솔을 비롯한 내염성이 강한 수종들이 군락을 이루고 있기 때문에 곰솔-졸참나무 군락을 제외한 군락들은 급격한 환경변화가 발생하지 않으면 현 상태의 군락 구조를 당분간 유지할 것으로 예상된다.
