국립 용현자연휴양림일대 산림유전자원보호구역의 관속식물상

The Flora of Protected Area for Forest Genetic Resource Conservation in the National Yonghyeon Natural Recreation Forest, South Korea

본 연구는 국립용현자연휴양림일대 관속식물상을 밝히고 주요 식물의 분포를 파악하고자 2014년 2월부터 2014년 9월까지총 7회에 걸쳐 조사를 실시하였다. 관속식물은 95과 280속 398 종 3아종 50변종 9품종의 총 460분류군이며, 이 중 한국 특산식물은 총 6분류군, 산림청 지정 희귀식물은 8분류군이 조사되었다. 식물구계학적 특정식물종은 Ⅳ등급 7분류군, Ⅲ등급 7분류군, Ⅱ등급 12분류군, Ⅰ등급에는 17분류군 등 총 43분류군이분포하고 있었다. 귀화식물은 39분류군으로 확인되었으며, 귀화율은 8.5%로 나타났다. 조사된 470분류군의 유용도는 식용189분류군(41.1%), 약용 155분류군(33.7%), 목초용 177분류군(38.5%), 관상용 52분류군(11.3%), 목재용 17분류군(3.7%), 섬유용 12분류군(2.6%), 공업용 3분류군(0.7%)로 나타났다. 본연구지역은 식생은 양호하나 인위적인 간섭에 의한 훼손이 일어나고 있으며, 장기모니터링을 통해 관속식물상과 식생 동태파악이 이루어져야 할 것으로 판단된다.

This study was carried out to investigate the vascular plants of the protected area for forest genetic resource conservation in the National Yonghyeon natural recreation forest. The vascular plants collected 7 times (from February to September 2014) were consist of total 460 taxa; 95 families, 280 genera, 398 species, 3 subspecies, 50 varieties and 9 forms respectively. The 6 taxa of Korean endemic plants and 8 taxa of Korean rare plants were investigated. The floristic regional indicator plants found in this area were 43 taxa comprising 7 taxa of grade Ⅳ, 7 taxa of grade Ⅲ, 12 taxa of grade Ⅱ, 17 taxa of grade Ⅰ. The naturalized plants were 39 taxa, therefore naturalized ratio was 8.5%. 460 taxa listed consist of 189 taxa (41.1%) of edible plants, 155 taxa (33.7%)of medicinal plants, 177 taxa (38.5%) of pasture plants, 52 taxa (11.3%) of ornamental plants, 17 taxa (3.7%)of timber plants, 12 taxa (2.6%) of fiber plants and 3 taxa (0.7%) of industrial plants. The vegetation status of investigated area was comparatively well conserved, but human-induced damage is increasingly greater. Therefore, a long-term monitoring of vascular plants and vegetation movement must become accomplished.
