순천시 조계산 운수암 계곡부 식물군집구조 The Structure of Plant Community of the Woonsooam Valley in Jogyesan (Mt.), Suncheon
pp.45-54
본 연구는 순천시 조계산(해발고 884.3m) 운수암 계곡부를 대상으로 식물군집구조를 조사 분석하여 식생구조 특성과 생태적 천이계열, 보전가치를 밝히고 기초자료를 제공하고자 수행하였다. 조사구는 해발고 255~495m에 20m×20m 크기의 15개소를 설정하였다. DCA 기법에 의한 군집분류 결과 군집 Ⅰ(소나무군집), 군집 Ⅱ(굴참나무-졸참나무군집), 군집 Ⅲ(졸참나무-굴참나무군집), 군집 Ⅳ(개서어나무-졸참나무군집), 군집 Ⅴ(낙엽활엽수군집) 등 다섯 개의 식물군집으로 분류되었다. 순천시 조계산 일대는 온량지수를 분석한 결과 온대남부기후대의 식생이었다. 조계산 운수암 계곡부는 졸참나무군집 34.4%, 졸참나무-군참나무군집 32.1%로 계곡부 사면을 중심으로 우점하여 분포하였으며, 계곡부를 중심으로 개서어나무군집이 5.5% 분포하였다. 관목층에서는 조릿대가 우점하고 있었다. 생태적 천이계열은 추정하기 어려웠으나, 장기적으로 모니터링을 통해 군집별 변화양상을 규명할 수 있을 것이다. 샤논의 종다양도지수(400㎡)는 군집 Ⅲ(1.0102~1.1013), 군집 Ⅴ(0.9945), 군집 Ⅱ(0.7913~1.1503), 군집 Ⅳ(0.8081~1.0749), 군집 Ⅰ(0.9273) 순으로 높았다.
This study was carried out to investigate the ecological succession sere and conservative value, and to provide the basic data in Woonsooam Valley, in Jogyesan (Mt.) (altitude 884m), Suncheon City, Korea by analysing the structure of the plant community. Fifteen plots (size is 20m×20m) were set up at an altitude of range from 255m to 495m. As a result of analysis of DCA which is one of the ordination technique, the plant communities were divided into five groups which are community Ⅰ (Pinus densiflora community), community Ⅱ (Quercus variabilis-Quercus serrata community), community Ⅲ (Q. serrata-Q. variabilis community), and community Ⅳ (Carpinus tschonoskii-Q. serrata community) and community Ⅴ(Deciduous broad-leaved forest community). We found out that the vegetation of the study site located in the South Temperate Climate Zone. The study site is found out that Q. serrata community 34.4%, part of slope in valley is the distribution that dominant species is Q. serrata-Q. variabilis community 32.1%. And in valley showed Carpinus tschonoskii community 5.5%. And Sasa borealis was dominant species in the shrub layer. We couldn’t supposed that the ecological succession sere of the study site, however we should do a long-term monitoring to investigate the changes of the ecological succession each plant community, According to the index of Shannon's diversity (unit: 400㎡), communityⅢ was ranged from 1.0102 to 1.1013, community Ⅴ was 0.9945, community Ⅱ was ranged from 0.7913 to 1.1503, community Ⅳwas ranged from 0.8081 to 1.0749 and community Ⅰwas 0.9273.
