Abstract

The vascular plants in the Eco-Arboretum site, Mt. Gumwon appeared to be 369 taxa; 84 families, 217 genera, 319 species, 43 varieties and 7 forms. Based on the list of the rare plants, 2 taxa existed in the studied areas; Abies koreana (Preservation priority order; No. 73), Paeonia obovata (No. 97) and based on the list of Korean endemic plants, 12 families, 14 genera, 11 species, 3 varieties, 1 hybrid, 15 taxa existed; Cephalotaxus koreana, Abies koreana (Planted species), Carex okamotoi, Salix hallaisanensis, Salix purpurea var. japonica, Clematis trichotoma, Thalictrum actaefolium, Lespedeza ${\times}$ tomentella, Vicia nipponica, Stewartia koreana, Hypericum attenuatum var. confertissimum, Paulownia coreana (Planted species), Weigela subsessilis, Aster koraiensis (Planted species). Specific plant species by floral region were total 38 taxa; Paeonia obovata in class V , 13 taxa (Lilium leichtlinii var. tigrinum, Betula costata, Betula davurica, Ulmus davidiana, Spiraea frutschiana, Prunus maackii, Syringa reticulata var. mandshurica, Cynanchum inamoenum, Lonicera subhispida, Cacalia firma, etc.) in class III , 5 taxa (Heloniopsis orientalis, Chrysosplenium pilosum, Acer triflorm, Viola tokubuchiana var. takedana, Teucrium veronicoides, etc.) in Class II . 19 taxa (Dryopteris erythrosora, Arisaema ringens, Veratrum versicolor, Polygonatum inflatum, Salix glandulosa, Betula schmidtii, Alnus hirsuta, Quercus variabilis, Aconitum japuense, Dicentra spectabilis, Chrysosplenium flagelliferum, Impatiens noli-tangere, Ilex macropoda, Tilia amurensis, Fraxinus mandshurica, Trigonotis icumae, etc.)in class I . The naturalized plants in this site were 5 families, 13 genera, 15 taxa (Rumex acetocella, Rumex obtusifolius, Trifolium repens, Oenothera odorata, Erigeron annuus, Erigeron philadelphicus, Bidens frondosa, Taraxacum officinale, etc.) and naturalization rate was 4.1% of all 369 taxa vascular plants.

본 연구는 금원산 생태수목원 조성 부지의 관속식물상을 조사한 후 희귀 및 특산식물, 식물구계학적 특정식물종, 귀화식물 등을 분류함으로써, 생태수목원 조성을 위한 기초자료를 제공하고자 수행한 바 다음과 같은 결론을 도출하였다. 금원산 생태수목원 조성 부지의 관속식물상은 84과 217속 319종 43변종 7품종으로 총 369분류군이 확인되었다. 희귀식물은 구상나무(보존우선순위; 73번)와 산작약(97번)이 확인되었다. 특산식물은 개비자나무, 구상나무(식재), 지리대사초, 떡버들, 키버들, 할미밀망, 은꿩의다리, 털조록싸리, 네잎갈퀴나물, 노각나무, 큰고추나물, 오동(식재), 병꽃나무, 벌개미취(식재) 등 12과 14속 11종 3변종 1교잡종으로 총 15종류가 확인되었다. 식물구계학적 특정식물종은 V등급에 산작약, IV등급에는 확인되지 않았으며, III등급에 구상나무(식재), 중나리, 거제수나무, 물박달나무, 당느릅나무, 참조팝나무, 개벚지나무, 꽝꽝나무(식재), 노각나무, 개회나무, 선백미꽃, 털괴불나무, 병풍쌈 등 13종류, II등급에 처녀치마, 털괭이눈, 복자기, 민둥뫼제비꽃, 곽향등 5종류, I등급에 홍지네고사리, 개비자나무, 전나무(식재), 잣나무(식재), 큰천남성, 흰여로, 퉁둥굴레, 왕버들, 박달나무, 물오리나무, 굴참나무, 투구꽃, 금낭화, 애기괭이눈, 노랑물봉선, 대팻집나무, 피나무, 들메나무, 덩굴꽃마리 등 19종류로 정리되어 총 38종류가 확인되었다. 귀화식물에는 큰조아재비, 큰김의털, 오리새, 호밀풀, 애기수영, 돌소리쟁이, 아까시나무, 족제비싸리, 토끼풀, 달맞이꽃, 개망초, 봄망초, 미국가막사리, 원추천인국, 서양민들레 등 5과 13속 15종류가 확인되었으며, 귀화율은 전체 369종류의 관속식물 중 4.1%로 분석되었다.
