초록

부산 금정산 범어사계곡의 낙엽활엽수가 우점하는 군락의 식생구조를 분석하기 위해 단위면적 100$m^2$의 조사구 28개를 설정하고 조사를 실시하였다. Classification기법중의 하나인 TWINSPAN을 이용하여 군락을 분류한 결과, 개서어나무-낙엽활엽수군락(군락 I), 졸참나무-개서어나무군락(군락 II), 개서어나무-졸참나무-소나무군락(군락 III), 개서어나무-졸참나무-신갈나무군락(군락 IV), 졸참나무-낙엽활엽수군락(군락 V), 편백-개서어나무군락(군락 VI)의 6개 군락으로 최종 분리되었다. 군락별 종다양도는 0.3832~1.0450의 범위이었으며 인공식재한 편백나무가 우점하는 군락 VI의 종다양도가 가장 낮았고 개서어나무와 기타 낙엽활엽수가 우점하는 군락 I과 군락 V의 종다양도가 가장 높았다. 단위면적당(100$m^2$) 종수는 6.8${\pm}$3.2종이었다. 금정산 범어사계곡의 개서어나무군락은 기후극상림으로써 보전가치 높으므로 지속적인 보전관리대책이 요구된다.

The purpose of this study is to investigate the structure of vegetation dominated by deciduous broad-leaved trees at the Beomeosa(Temple) Valley of Mt. Kumjungsan in Busan. To this end, 28 plots were set up and surveyed. The result analyzed by TWINSPAN, one of the classification technique, showed that the communities were divided into six groups which are Carpinus tschonoskii-Deciduous broad-leaved forest community(I), Quercus serrata-C. tschonoskii community(II), C. tschonoskii-Q.s serrata-Pinus densiflora community(III), C. tschonoskii-Quercus serrata-Q. mongolica communtiy(IV), Q. serrata-Deciduous broadleaved forest community(V) and Chamaecyparis obtusa-C. tschonoskii community (VI). Species diversity ranged from 0.3832 to 0.0450. The lowest diversity was Chamaecyparis obtusa community(VI) but the highest was Carpinus tschonoskii-Deciduous broad-leaved forest community(I) and Q. serrata-Deciduous broadleaved forest community(V). The average number of species was 6.8${\pm}$3.2 in the unit area(100$m^2$). Carpinus tschonoskii community at the Beomeosa Valley of Mt. Geumjeongsan was a climatic climax forest having a value to preserve, so a continuous management will be needed.
