초록
본 연구는 강원도 양구군 DMZ 접경지역에 위치한 봉화산(874.9m)의 관속식물을 밝히고 보전이 필요한 주요 식물과 자원 식물들의 분포를 파악하고자 수행되었다. 2015년 5월부터2017년 4월까지 총 10차례에 걸쳐 조사된 관속식물은 93과 309 속 358종 4아종 58변종 5품종으로 총 525종이 파악되었다. 그중산림청에서 지정한 희귀식물은 개느삼, 삼지구엽초, 쇠채 등 총12분류군, 한국 특산식물은 진범, 요강나물, 고려엉겅퀴 등 총17분류군이 확인되었고, 식물구계학적 특정식물은 Ⅴ등급에 해당하는 삼지구엽초, 개느삼 등을 포함하여 총 80분류군이 분석되었다. 외래식물은 31분류군으로 파악되었으며 귀화율과 도시화지수는 각각 5.8%, 7.25%로 나타났다. 조사된 525분류군의 유용도는 식용자원으로 분류되는 식물 213분류군(40.9%), 목축 및 사료 자원으로 이용되는 식물 196분류군(37.2%), 약용식물 172분류군(32.6%), 관상용 50분류군(9.5%), 목재용, 염료용, 섬유용으로 이용되는 식물이 각각 23분류군(4.3%), 10분류군(1.9%), 6분류군(1.1%)으로 분석되었다.
Abstract
Mt. Bonghwa reaches a height of 800 m (2,870 ft) and stands on the flank of Mt. Daeam-san, which has an elevation of 1,304 m (4,278 ft). It is important to survey the flora of Bonghwa-san in that it is a way to make out what kind of plant species exist in DMZ due to the geographical characteristics of Bonghwa-san adjacent to Korean DMZ. Therefore this study was conducted to elucidate the distribution of vascular plants and their value of Bonghwa-san. The vascular plants that were collected 10 times from May 2015 to April 2017 consisted of a total of 525 taxa; 93 families, 309genera, 458 species, 4 subspecies, 58 varieties and 5 forms. The observed rare plant species as designated by Korea Forest Service were 12 taxa including Echinosophora koreensis, Epimedium koreanum, Anemone koraiensis etc. Endemic species were 16 taxa containing Cirsium setidens, Heloniopsis koreana, Salvia chanryoenica etc. 31 taxa were recorded as naturalized plants and their naturalized rate and urban index were noted as 5.8% and 7.25%. Among the surveyed 525 taxa, edible, medicinal, pasturing, ornamental, timber, dye, fiber and industrial plants included 213 taxa, 172 taxa, 196 taxa, 50 taxa, 23 taxa, 10 taxa, 6 taxa and 3 taxa, respectively.
