승마산(경기도)의 관속식물상 The Vascular Plants in Mt. Seungma (Gyeonggi-do)
pp.297-312
본 연구는 승마산의 관속식물상을 밝히고 주요 식물을 조사하였다. 2011년 3월부터 10월까지 총 13회에 걸쳐 수행되었다. 그 결과 관속식물은 94과 260속 340종 5아종 37변종 2품종으로 총 384분류군이 확인되었다. 한국 고유종은 외대으아리, 진달래, 개나리, 오동나무 등 9분류군이 확인되었다. IUCN 평가기준에 따른 희귀식물은 멸종위기종(CR)인 왕벚나무, 취약종(VU)인 삼지구엽초, 약관심종(LC)인 모새달이 조사되었다. 식물구계학적 특정식물종은 V등급 2분류군, III등급 2분류군, II등급 1분류군, I등급 10분류군 등 15분류군이 발견되었다. 생활형조성은 일년생식물(28.3%), 반지중식물(23.0%), 수생식물(14.3%)등이 높게 나타났다. 귀화식물은 43분류군으로 확인되었으며, 귀화율은 11.2%로 나타났다. 조사지역의 식생은 양호하나 최근 들어 인위적인 간섭에 의한 훼손이 증가되고 있다. 따라서 장기적인 모니터링을 통한 식생변화와 동태파악이 이루어져야 할 것으로 판단된다.
This study was carried out to investigate the flora of Mt. Seoungma (Gyeonggi-do). The vascular plant were collected 13 times (from March to October 2011), and 384 taxa in total were identified, including 94 families, 260 genera, 340 species, 5 subspecies, 37 varieties and 2 forms. Korean endemic plants of this area were nine taxa; Clematis brachyura, Rhododendron mucronulatum, Forsythia koreana, Paulownia coreana, etc. Rare plants (IUCN) by the Korean Forest Service and Korean National Arboretum three taxa were recorded; one Critically Endangered species (CR), Prunus yedoensis, one Vulnerable species (VU), Epimedium koreanum, one Least Concemed species (LC), Phacelurus latifolius. The floristic regional indicator plants found in this area were 15 taxa comprising two taxa of grade V and III, one taxa of grade II, 10 taxa of grade I. Furthermore, therophytes (28.3%), hemicryptophytes (23.0%), hydrophytes (14.3%) showed high proportional ratio in life form spectrum. The naturalized plants were identified as 43 taxa and the percent of naturalized index (NI) was 11.2% of total 384 taxa vascular plants. The vegetation status of investigated area was comparatively well conserved, but the degree of damage was increasing rapidly by the disturbances of human beings. Therefore, a long-term monitoring of vegetation changes and movement grasp must become accomplished.
