ABSTRACT
Forest vegetation classification and species composition of Mt. Ilwol, Yeongyang-Gun, Korea, were studied combining the Braun-Blanquet approach with numerical syntaxonomical analyses (TWINSPAN). Vegetation types and various ecological characteristics such as flora, constancy classes, species ratio of life-form, species diversity and importance value were analyzed. Sixty-eight samples were taken from a 100m2 square plot each. Forest communities were identified as two great types: arid landform of mountainside (AM) and humid fertility of piedmont and valley (HP). The former was divided into 3 communities (Rhododendron mucronulatum, Quercus variabilis, Hosta capitat community) and 2groups, and the latter into 3 communities (Tilia amurensis, Vitis coignetiae, Philadelphus schrenckii community) and 2 groups. Vegetation was classified into 8 units. Floristically, the most represented family was Compositae with 26 species. Species with percentage constance degree of more than 61% was Quercus mongolica (72.1%, IV); Carex siderosticat (III) and Fraxinus rhynchophylla (III) were 50.0 and 41.1%, respectively. Life-forms species ratios for trees, subtrees, shrub, vines, grominoids, forbs and ferns were 18.5, 5.7, 14.9, 6.6, 8.8, 42.4 and 3.1%, respectively, PH type showed from 1.70±0.50 to 1.97±0.57 and AM type was from 1.40±0.18 to 1.62±0.20 in species diversity; therefore, the former type showed higher species diversity than the latter, According to importance value analysis, Pinus densiflora, Quercus mongolica and Q. variabilis were higher in the tree layer, Q. mongolica in the subtree layer, Fraxinus sieboldiana, R. schlippenbachii, etc. in the shrub layer and Carex siderosticta, Carex humilis, etc. in the herb layer.

일월산 산림식생의 종구성적 특성을 파악하기 위하여 조사구 68개소(10m×10m)를 설정하여 식생유형과 그에 대한 특성(현존식물상, 상재도급과 생활형분포율, 종다양도, 층위별 중요치)을 분석하였다. 식생유형은 산악건조지식생형과 비옥적윤한 산록과 계곡부식생형으로 대별되었으며, 전자는 3개 군락(진달래군락, 굴참나무군락, 일월비비추군락), 2개 군(잣나무군, 진달래전형군), 후자는 3개군락(피나무군락, 머루군락, 고광나무군락), 2개 군(당단풍군, 참반디군)으로 구분되어 총 8개 식생단위로 나타났다. 관찰된 총 252종에서 국화과가 26종, 백합과 19종, 미나리아재비과 15종, 장미과 14종 등의 순으로 높게 나타났고, 상재도급별 분포경향에서 신갈나무(IV), 대사초(III), 물푸레나무(III)가 고중상재도종으로 나타났다. 생활형 분포율은 교목성이 18.5%, 소교목성 5.7%, 관목성 14.9%, 만목성 6.6%, 화본과류 8.8%, 광역초본 42.4%, 양치식물 3.1%로 나타났으며, 종다양도는 PH유형이 1.70±0.50~1.97± 0.57로 1.40±0.18~1.62±0.20인 AM유형 보다 높은 값을 나타내었다. 교목층에서는 소나무, 신갈나무, 굴참나무 등의 중요치 값이 높게 나타났으며, 아교목층은 신갈나무, 관목층은 쇠물푸레, 조록싸리, 철쭉꽃, 생강나무, 진달래, 초본층은 대사초, 산거울, 큰기름새의 영향력이 높게 나타났다.
