우리나라 석회암지대는 한반도에서 그다지 넓지 않은 좁은 지역에 집중적으로 분포하고 있고, 독특한 생태계 지역이므로 석회암지대 산림관리를 위한 기초자료를 제공하고자 산림식생의 유형분류, 산림토양의 이화학적 특성, 환경요인과 식생유형의 상관관계 등을 구명한 결과, 식생은 굴참나무군락군과 신갈나무군락군의 2개 군락군으로 크게 분류되었고, 기타 하위식생단는 4개 군락, 6개 군, 2개 소군으로 세분되어 총 8개의 식생단위로 나타났다. 석회암지대 조사지의 토성은 미사질양토로 나타났고, A층의 토양산도는 7.55로 나타났으며, 치환성 양이온인 칼슘(Ca2+)과 마그네슘(Mg2+) 함량은 각각 평균 26.04cmolc/kg와 2.93cmolc/kg으로서 매우 높게 나타났다. 굴참나무군락군은 pH가 높고, 사면경사가 급하고, 노암율이 높으며, Ca 이온의 농도가 높은 입지에 주로 분포하는 경향이었고, 신갈나무군락군은 표고가 높은 입지에 분포하는 경향이었다.

The purpose of this study was to explain community structure for actual vegetation and their environment variables in Anmyeon Island. Samples were collected for 106 plots using ZM phytosociology method and coincidence method. Actual vegetation were classified into three vegetations types(forest vegetation type, maritime vegetation type, lake vegetation type) and eleven community units. Pourthiaea villosa community in forest vegetation type was divided into 5 groups such as Carpinus coreana group, Pinus rigida group, Chamaecyparis obtusa group, Castanea crenata group and Typical group. Maritime vegetation type was divided into 3 communities, such as Vitex rotundifolia community, Koelreuteria paniculata community and Suaeda japonica community. V. rotundifolia community was subdivided into 2 groups, Rosa rugosa group and Diodia teres group. K. paniculata community was subdivided into 2 groups, Grewia biloba var. parviflora group and Typical group. Lake vegetation type was divided into 1 community, Nelumbo nucifera community. And it was entirely classified into 11 community units.

The purpose of this study was to explain relationship between community structure and their environment variables in Mt. Hwaak. Samples were collected by 101 plots using ZM phytosociological method and followed by cluster, importance value and canonical correspondence analysis. The forest vegetation classified into 8 community types such as Pinus densiflora community, Berberis amurensis community, Betula ermani community, Betula schmidtii community, Larix leptolepis community, Pinus koraiensis community, Cornus controversa community and Salix koreensis community. Altitude was considered as the highest factor correlated to the community types. Berberis amurensis community and Betula ermani community were located in upper slope area of high elevation, Cornus controversa community and Salix koreensis community in valley area, and Pinus densiflora community in ridge area, respectively.
