초록
난대 상록활엽수림 복원 모형 연구의 사례지인 완도의 식생구조를 조사하였다. 완도의 사록활엽수림은 붉가시나무가 우점종이었으며, 수령 30여년 미만의 맹아림이 대부분이었다. 중복부와 산록부에는 조림식생과 낙엽활엽수림이, 능선부와 고지대에는 졸참나무, 개서어나무, 소사나무 등의 낙엽활엽수림이 발달하고 있었으며, 임상층에서 상록활엽수종이 활착하고 있었다. 47개 조사구에서 60% 이상의 상재도를 나타낸 상록활엽수종은 광나무, 마삭줄, 붉가시나무, 사스레피나무이었다. 본 조사지역 내에 출현한 관속식물상은 101과 321속 426종 56변종, 5품종 및 1교잡종 등 촌 488종류로 파악되었으며 이 중에서 상록성 수목은 23속 30종 2변종 등 32종류이었다. 12개 조사지역에서 100%의 상재도를 나타낸 종은 맥문동과 칡이었으며, 50% 이상인 종은 덜꿩나무, 마삭줄 등 40종류이었다. 한편 상재도가 8% 이하인 식물종은 가래나무, 말채나무, 병아리꽃나무 등 209종류이었다. 식물종 다양성은 장기간 인간간섭으로 조사지역간 특이한 사항은 보이지 않았으나, 곰솔림이 155종으로 가장 높은 값을 보인 반면에 생달나무-마삭줄군락은 23종으로 가장 낮은 값을 나타내었다.
To study restoration model of evergreen broad-leaved forests in warm temperate region, vegetation structure was studied at Wando(Island) as a case study. Quercus acuta was a dominant species at evergreen broad-leaved forests in Wando(Island). Majority of evergreen broad-leaved forests was a thirty years old coppice forest. Reforested vegetation and deciduous broad-leaved forests was developed at a mid-slope districts and a piedmont. Deciduous broad-leaved forestsconsisted of Quercus serrata, Carpinus tschonoskii, Carpinus coreana, etc., was developed at a ridge and higher districts. Evergreen broad-leaved woody plants were growing at a forest floor of deciduous broad-leaved forests. The species over sixty percent of constanty ratio in forty seven plots were Ligustrum japonicum, Trachelospermum asiaticum var. intermedium, Quercus acuta and Eury japonica. The vascular plants in the Wando(Island) was summarized as 488 taxa which composed as 101 families, 321 genus, 426 species, 56 varieties, 5 forms and 1 hyvrid. Evergreen broad-leaved woody stecies was 32 taxa which composed as 23 genus, 30 species and 2 varieties. The species such as Liliope platyphylla of Liliaceae and Pueraria thunbergii of Leguminosae, etc. was recorded as the highest values for their widely distribution in the areas. On the contrary, and forty taxa of plants such as Viburnum erosum of Caprifoliaceae, Traceholospermum asiaticum var. intermedium was recorded as over 50% of constancy ratio. Two hundred and nine taxa of plants such as Juglans manshurica of Juglandaceae, Cornus walteri of Cornaceae and Rodotypos scandens of Rosaceae, etc. was showed the specific trends due to long-term artificial disturbance. The forest of Pinus thunbergii showde the highest species diversities(155 species per 600m$^{2}$), while the Cinnamomum japonicum-Tracheolospermum asiaticum var. intermedium community showed the lowest species diversities(23 species per 600m$^{2}$).
