This study was carried out to analyze vegetation and soil characteristic, and ordination of Scrophularia takesimensis population, Ulleung Island. The Scrophularia takesimensis population was classified into Aster spathulifolius for. oharai dominant population, Vitis amurensis dominant population and Scrophularia takesimensis typical population. The Scrophularia takesimensis population was located in elevation of 1m to 6m, in Ulleung Island. In the study sites, soil organic matter, nitrogen, available phosphorous, exchangeable potassium, exchangeable calcium, exchangeable magnesium and exchangeable sodium concentration, and cation exchange capacity, and soil pH were 9.1~19.1%, 0.19~0.52%, 87.1~196.7mg/kg, 2.0~2.8cmol+/kg, 5.4~5.9cmol+/kg, 5.9~8.8cmol+/kg, 4.4~4.8cmol+/kg, 20.3~ 26.7cmol+/kg, and 6.8~8.0, respectively. The Vitis amurensis dominant population was mainly found in the high percentage of total nitrogen, organic matter, CEC in comparison with Aster spathulifolius for. oharai dominant population.

본 연구는 설악산 대청봉지역의 아고산식물대에 분포하고 있는 식물군락을 분류하고, 식생과 토양환경과의 관계를 밝혀 이들을 보존하는데 필요한 기초 자료를 제공하고자 실시하였다. 대청봉지역의 아고산대 식물군락은 털진달래-사스래나무군락군으로 구분되었으며, 입지 환경에 따라 종조성을 달리하는 눈잣나무군락, 분비나무군락, 눈측백군락, 털진달래-사스래나무전형군락으로 구분되었다. 군락별 환경요인과 식생과의 ordination 분석 결과, 눈잣나무군락과 눈측백군락은 분비나무군락과 털진달래-사스래나무전형군락보다 전질소, 유효인산, 유기물함량 등의 양료가 다소 많은 입지에 분포하고 있었다. 분비나무군락과 털진달래-사스래나무전형군락이 눈잣나무군락과 눈측백군락보다 해발고가 다소 높은 입지에 분포하고 있었고, 눈잣나무군락과 눈측백군락은 북사면이나 북서사면에, 분비나무군락과 털진달래-사스래나무전형군락은 남서사면에 분포하는 것으로 나타났다. This study was carried out to analyze vegetation and soil characteristic, and ordination of subalpine forest vegetation of Daecheongbong area, Mt. Seorak. Communities by characteristic in species composition of subalpine forest were classified into Rhododendron mucronulatum var. ciliatum-Betula ermani community group, Pinus pumila, Abies nephrolepis, Thuja koraiensis, and Rhododendron mucronulatum var. ciliatum-Betula ermanii typical community. The results of the correlation between forest communitie sand soil conditions of Daecheongbong area by DCCA ordination method are as follows: The Pinus pumila community and Thuja koraiensis community were mainly found in the high percentage area of total nitrogen, available phosphorous, organic matter in comparison with Abies nephrolepis community and Rhododendron mucronulatum var. ciliatum-Betula ermanii typical community. The Abies nephrolepis community and Rhododendron mucronulatum var. ciliatum-Betula ermanii typical community were mainly found in the high elevation area in comparison with Pinus pumila community and Thuja koraiensis community. The Pinus pumila community and Thuja koraiensis community were mainly found in the northern and northwestern direction, but Abies nephrolepis community and Rhododendron mucronulatum var. ciliatum-Betula ermanii typical community were mainly found in the southwestern direction.
