본 연구는 계방산 가문비나무 및 전나무 임분의 산림식생유형분류와 정량적 분석을 위하여 Z-M 식물사회학적 방법으로 식생구조의 유형분류를 실시한 결과, 군락단위에서 가문비나무군락, 전나무군락으로 분류되었으며 가문비나무군락은 군단위에서 흰인가목군과 부게꽃나무군으로 세분되었으며, 전나무군락은 복장나무군과 생강나무군으로 세분되었다. 분류된 식생단위를 기준으로 중요치를 산출한 결과, 가문비나무는 식생단위 1과 2의 교목층에서 각각 30.73%, 20.25%로 비교적 높게 나타나 당분간 가문비나무의 우점이 계속될 것이라 판단되었다. 또한 종다양도를 분석한 결과 식생단위 4의 종다양도 지수는 0.6976으로 가장 낮았으며, 식생단위 2의 종다양도 지수는 1.1256으로 가장 높게 나타났다. 군락간의 유사도는 식생단위 1과 4, 2와 4가 각각 0.2880과 0.3626으로 낮게 나타났으며 식생단위 1과 2, 3과 4의 군락유사성은 각각 0.5411과 0.5041로 나타나, 군락 간 구성종의 차이가 크지 않은 군락으로 판단되었다. 종간연관에 대한 Chi-square matrix와 성좌표를 각각 분석한 결과, 크게 2개의 유형으로 나뉘어졌는데 Ⅰ유형의 식물 종들은 대부분 식물사회학적으로 분류된 가문비나무군락에서 주로 출현하는 식별종과 표징종이었으며, Ⅱ유형의 식물종은 전나무군락에서 주로 출현하는 식물종으로, 비교적 습한 곳에 나타나는 종들로 나뉘어졌다. 이러한 결과는 각 수종들이 선호하는 생육환경이 비슷한 종들끼리는 정의 상관이 인정되고, 선호하는 환경이 다른 종들끼리는 부의 상관을 보이는 것으로 판단된다.
In this study, for the forest vegetation classification and the quantitative analysis of the Picea jezoensis and Abies hollophylla stand, the type classification of the vegetation structure was performed with Z-M phytosociological method, and as a result, it was classified into the Picea jenoensis community and the Abies holophylla community in the community unity. The Picea jezoensis community was subdivided into the Rosa koreana group and the Acer ukurunduense group in the group unity and the Abies holophylla community was subdivided into the Acer mandshuricum group and the Lindera obtusiloba group. In the results of estimating the importance value based on the classified vegetation unity, it was deemed that the dominance of the Picea jezoensis would be continued for a while as the importance value from the tree layers of vegetation unity 1 and 2 represented relatively high with 30.73% and 20.25%. In addition, in the results of analyzing the species diversity to estimate the maturity of the community, the species diversity index of the vegetation unity 4 was the lowest with 0.6976 and that of vegetation unity 2 was the highest with 1.1256. As in the similarity between the communities, the vegetation unit 1 and 4 and the vegetation unit 2 and 4 represented low with 0.2880 and 0.3626, respectively, and the similarity between the vegetation unit 1 and 2 and between 2 and 4 represented 0.5411 and 0.5041, respectively, it was deemed that they were the communities that the difference in the composition species between the communities was not big. In the results of analyzing the Chi-square matrix and the catalog of constellations for the interspecific, they were divided mainly into two types, and type 1 plant species were mostly differential species and the characteristic species, which appeared in the Picea jezoensis community classified phytosociologically, and type II plant species were mostly the species appearing in the Abies holophylla community growing in the relatively damp places. Such results is deemed that the positive (+) correlation is recognized among the species, of which growing environments are similar, and the negative (-) correlation .represents among the species, of which preferential environments are different.
