본 연구는 강원지역 백두대간 천연림의 군집분류와 천이경향을 추정하기 위해 점표본법을 이용하여 향
로봉, 오대산, 석병산, 두타산, 덕항산, 함백산 등 총 6개 지역에서 식생조사를 실시하였다. 조사된 식생
자료를 바탕으로 Cluster 분석을 이용하여 6개 지역 총 28개의 군집으로 분류하였으며 군집의 속성을 밝
히기 위해 수종구성과 종다양성을 분석하였다. 분류된 28개 군집의 상층 수종구성을 바탕으로 군집의 이름을 명명하였고, 이들 군집을 중생혼합림, 기타활엽수림, 신갈나무군집, 신갈나무림, 소나무-신갈나무군집, 소나무림, 거제수나무군집, 신갈나무-잣나무군집등 총 8개의 산림유형으로 집약하였다. 종다양성지수가 낮은 소나무림, 소나무-신갈나무군집 등은 석병산, 두타산, 덕항산 등과 같이 해발고도 1,000 m 내외의 낮은 지형의 백두대간에 위치하였다. 종다양성지수가 높게 나타난 중생혼합림, 기타활엽수림 등은 향로봉, 오대산, 함백산 등과 같이 해발고도 1,400 m 내외의 비교적 높은 백두대간에 위치하였다. 천연활엽수림 내 신갈나무의 구성비율이 증가함에 따라 종다양성지수가 낮아지는 경향을 나타내었다.
On the basis of vegetation data collected by point-centered quarter method in analysis in
Baekdudaegan of Gangwon province in the area of Hyangrobong, Odaesan, Seokbyeongsan, Dutasan, Deokhangsan and Hambaeksan, the study was carried out to classify forest communities and to evaluate the successional trends. The classification method of cluster analysis was used to make various disordered forests into several common groups for 1,004 sample points all together. By clustering the forests in the six study areas were classified into 28 forest communities, which were subjected to aggregate 8 representative forest communities on the count of species composition and species diversity. They were Mesophytic mixed forest community, others deciduous forest community, Quercus mongolica (dominant) community, Q. mongolica (pure) community, Pinus densiflora - Q. mongolica community, P. densiflora community, Betula ermanii community and Q. mongolica - Pinus koraiensis community. The ecological outlook from the result indicated that P. densiflora community and P. densiflora – Q. mongolica community, which were located in
Seokbyeongsan, Dutasan and Deokhangsan around 1,000m above the sea level showed lower species diversity index. On the contrary Mesophytic mixed forest community, others deciduous forest community which was located in Hyangrobong, Odaesan and Hambaeksan mostly in protected area and national park around 1,500m above the sea level displayed higher species diversity index. As the composition ratio of Q. mongolica within a certain community was decreased, the species diversity was generally increased, assumed that abundance of Q. mongolica might be negatively associated with species diversity in the national deciduous forest.
