본 연구는 덕유산 국립공원 설천지구내에 건설되고 있는 무주리조트 골프장예정지의 식물군집구조를 밝히고 환경영향평가서의 식물생태계부분 재평가를 위해 실시하였다. 현존식생은 소나무-신갈나무-졸참나무군집이 33.2%, 참나무류군집이 27.3%, 소나무군집이 20.7%, 고산습지가 4.9%이었으며 본 조사지 삼림은 독특한 환경조건을 이루고 있었다. 녹지 자연도는 등급 8, 9가 전체의 93%를 차지하는 안정된 생태계를 구성하고 있었으며 환경영향평가서상의 녹지자연도등급 산정과 본 조사결과와는 많은 차이를 보였다. 54개 조사구에 대한 DCA 분석에서 분리된 군집은 6개로써 소나무군집, 소나무-신갈나무군집, 소나무-졸참나무-들메나무-물박달나무군집, 신갈나무-졸참나무-소나무군집, 신갈나무-굴참나무군집, 버드나무-물박달나무군집이었고 소나무군집을 제외한 기타의 군집은 소나무→참나무류로의 생태적 천이단계에 있는 것으로 예측되었다.

This study was conducted to investigated the plant community structure and to revaluate the part of plant ecosystem on statement of environmental impact assessment in Muju resort golf course, Solch'on area, Tokyusan National Park. The actual vegetation was comprised of Pinus densiflora-Quercus mongolica-Q. serrata community(33.21%), Q. spp. community(27.30%), P. densiflora community(20.68%) and high mountain marsh(4.93%) etc., which communities were the major vegetation and the forest vegetation was came to being a peculiar to environmental condition. The degree of green naturality 8, 9 was covered 93% in survey area, and so this result reflect the stability of ecosystem. There was all the difference between the statement of environmental impact assessment of development concerned and this study result in the estimation of degree of green naturality. The plant community were divided into six groups in fifty-four plots by DCA and the dividing groups were P. densiflora, P. densiflora-Q. mongolica, P. densiflora-Q. serrata-F. mandschurica-B. davurica, Q. mongolica-Q. serrata-P. densiflora, Q. mongolica-Q. variabilis, Salix koreansis- B. davurica community. Except P. densiflora forest in survey site, the ecological succession trend of the other communities was seemed to be from P. densiflora to Q. spp.
