본 연구는 온대 북부 기후대에 위치한 강원도 대관령 목장 산림생태계의 현존식생, 식물군집구조, 천이계열 특성과 보전가치를 밝히고, 향후 복원 및 관리계획 수립 시 필요한 기초자료를 제공하고자 수행하였다. 현존식생은 총 56개 유형으로 분류되었고, 조사면적 19,397,361㎡ 중 신갈나무가 우점하는 지역은 7,669,593㎡(39.1%), 1차 초지 지역은 4,785,417㎡(24.7%), 신갈나무-낙엽활엽수군집이 우점하는 지역은 2,182,276㎡(11.3%)이었다. 조사구는 20m×20m(400㎡) 28개소를 설정하였으며, DCA분석 결과 군집 Ⅰ(소나무-신갈나무군집), 군집 Ⅱ(신갈나무-소나무군집), 군집Ⅲ(신갈나무군집), 군집 Ⅳ(신갈나무-낙엽활엽수군집), 군집 Ⅴ(낙엽활엽수군집), 군집 Ⅵ(팥배나무군집) 등 6개의 식물군집으로 분류되었다. 표본목 수령은 군집 Ⅰ은 57~62년생, 군집 Ⅱ는 41~77년생, 군집 Ⅲ은 47~108년생, 군집Ⅳ는 47~82년생, 군집 Ⅴ는 47년생, 군집 Ⅵ은 55년생으로 전체적으로 41~108년생이었다. 대관령 목장의 생태적 천이는 소나무군집에서 신갈나무군집으로 발달하고 있는 것으로 예측되었으며, 계곡부를 중심으로 낙엽활엽수군집도 분포하고 있었다. 단위면적 400㎡당 샤논의 종다양도지수를 분석한 결과, 군집 Ⅳ(0.8203~1.1439) → 군집 Ⅲ(0.8019~1.1375) → 군집 Ⅴ(1.0993) → 군집 Ⅰ(0.9475~1.0797) → 군집 Ⅱ(0.6896~1.0324) → 군집 Ⅵ(0.9909) 순으로 높았다.
This study was carried out to investigate the actual vegetation, the structure of plant community, and ecological succession sere of forest ecosystem in temperate northern climate zone, Daegwallyeong Ranch, Gangwon-do (Province) and to offer the basic data for planning of the forest managemant. As a result of analysis of actual vegetation, vegetation types divided into 56types and the area of survey site was 19,397,361㎡. The ratio of vegetation type dominated by Quercus mongolica forest was 39.1%, primary grassland was 24.7%, Quercus mongolica-Deciduous broad-leaved forest was 11.3%. Twenty eight plots (size is 20m×20m) were set up and the results analyzed by DCA which in one of the ordination technique showed that the plant communities were divided into six groups which area community Ⅰ (Pinus densiflora-Quercus mongolica community), community Ⅱ (Quercus mongolica-Pinus densiflora community), community Ⅲ (Quercus mongolica community), community Ⅳ (Quercus mongolica-Deciduous broad-leaved community), community Ⅴ (Deciduous broad-leaved community), community Ⅵ(Sorbus alnifolia community). The age of community Ⅰwas ranged from 57 to 62 years old, that of community Ⅱwas ranged from 41 to 77 years old, community Ⅲwas ranged from 47 to 108 years old, community Ⅳwas ranged from 47 to 82 years old, community Ⅴwas 47 years old, community Ⅵwas 55 years old, thus we supposed that the age of the study site is about from 41 to 108 years old. The Ecological succession is predicted from Pinus densiflora community to Quercus mongolica community and Deciduous broad-leaved were distributed in the center of the valley in Daegwallyeong Ranch. According to the index of Shannon's diversity (unit: 400㎡), community Ⅳwas ranged from 0.8203 to 1.1439, community Ⅲ was ranged from 0.8019 to 1.1375, community Ⅴ was 1.0993, community Ⅰwas ranged from 0.9475 to 1.0797, community Ⅱwas ranged from 0.6896 to 1.0324, community Ⅵ was 0.9909.
