초록

본 연구는 사무산의 관속식물상을 밝히고 주요 식물을 조사하였다. 2014년 6월부터 2015년 10월까지 총 9회에 걸쳐 현지조사를 실시한 결과 관속식물은 108과 306속 424종 8아종 48변종4품종 1교잡종으로 총 502분류군이 확인되었다. 식물종다양성이 높은 과는 국화과(70분류군), 화본과(52분류군), 장미과(30 분류군), 콩과(28분류군), 사초과(20분류군)이었다. 한반도 고유종은 10분류군이며, IUCN 평가기준에 따른 적색목록식물은14분류군으로 확인되었다. 식물구계학적 특정식물은 Ⅴ등급 5 분류군, Ⅳ등급 11분류군, Ⅲ등급 14분류군, Ⅱ등급 10분류군,Ⅰ등급 21분류군으로 총 61분류군이 관찰되었다. 외래식물은43분류군으로 귀화율 8.6%, 도시화지수 13.4%로 나타났다. 삼림식생은 소나무림과 굴참나무림, 상수리나무림, 신갈나무림, 느티나무림, 아까시나무림으로 대별된다. 삼림의 수직구조는안정적이며, DBH-Class 분석 결과는 교목층의 우점종이 한동안 유지될 것으로 나타났다. 사무산은 식물종다양성이 높고 고유종, 희귀식물, 호석회성식물 등 주요 식물들이 다수 분포하며, 식물지리학적 가치가 높은 것으로 생각된다. 이러함에도, 인위적인 교란과 훼손에 대한 어떠한 보호조치도 없기 때문에생물자원이 지속적으로 소실되고 있다. 따라서 산림식생 보전을 위한 대책이 마련될 필요가 있다.

This study was carried out to investigate the flora and the vegetation of Samusan mountain on Jecheon-si, located in the middle part of the Korean peninsula. The vascular plants which were collected in 9 times from June 2014 to October 2015 were identified as 502 taxa in total, including 102 families, 314 genera, 445 species, 6 subspecies, 49 varieties, 1 form and 1 hybrid. The largest families were as follows; Asteraceae (70 taxa), Poaceae (52 taxa), Rosaceae (30 taxa), Fabaceae (28 taxa), and Cyperaceae (20 taxa). Of them, Korean endemic plants numbered 10 taxa, and vascular plants listed in the red data according to the International Union for Conservation of Nature (IUCN) numbered 14 taxa. The floristic regional indicator plants found in this area were 61 taxa in total. Among them, 5 taxa revealed the floristic grade Ⅴ, 11 for floristic grade Ⅳ, 14 for floristic grade Ⅲ, 10 for floristic grade Ⅱ, and 21 for floristic grade Ⅰ. The alien plants were identified as 43 taxa and the percentage of naturalized index (NI) was 8.6%, and urbanization index (UI) was 13.4%, respectively.
Samples of the forest vegetation on the Samusan Mt. were mainly classified as Pinus densiflora, Quercus variabilis, Q.
acutissima, Q. mongolica, Zelkova serrata and Robinia pseudoacacia forest. The vertical structures of the forest were stable and the DBH-Class analyses showed that the dominant tree species would be maintained. In the surveyed areas, high plant diversity was shown, and a number of endemic, rare, calcicole plants and phytogeographically important plants were found.
Nonetheless, numerous and diverse biological resources native have been consistently disturbed or damaged by human activities without some form of protection. Therefore, it is needed to set up strategies for conservation forest vegetation in this study area.
