Abstract
This study was performed to investigate the distribution of vascular plants and their usefulness in Mt. Hwaak (931m). The vascular plants were consisted of total 338 taxa; 92 families, 248 genera, 281 species, 1 subspecies, 47 varieties and 9 forms. It corresponded to 6.9% of totally 4,881 taxa distributed in Korea. The economic plants of this area were 278 taxa. It corresponded to 82.2% of collected plants in this area. Among the economic plants, there were 154 taxa of edible source, 163 taxa of medicinal source, 58 taxa of ornamental source, 91 taxa of pastural source, 22 taxa of industrial source and 9 taxa of timber source. Korean endemic plants of this area were 9 taxa. The rare and endangered plants was 1 taxon, and the specific species floristically of $I\;{\sim}\;V$ grades were 21 taxa. The naturalized plants were 19 taxa and naturalized ratio was 5.6% and Urban index was 6.8%.
본 연구는 화악산(931m)의 관속식물 분포를 파악하기 위하여 수행되었다. 2006년 5월부터 2007년 10월까지 6회에 걸쳐 채집된 관속식물은 총 92과 248속 281종 1아종 47변종 9품종의 총 338종류로 정리되었으며, 이는 한반도의 관속식물 4,881종류의 6.9%에 해당되었다. 조사 지역에서 분포하고 있는 338종류의 식물자원 유용도를 분석한 결과 총 278종류의 자원식물로 분류되었으며, 식용자원(E)은 154종류(55.3%), 약용자원(M)은 163종류(58.6%), 관상자원(O)은 58종류(20.8%), 초지자원(P)은 91종류(32.7%), 공업원료자원(I)은 22종류(7.9%), 목재자원(T)은 9종류(3.2%)로 나타났다. 특기할만한 식물로는 한국특산식물이 9종류, 산림청 지정희귀 및 멸종위기식물이 1종류, 식물구계학적 특정식물이 21종류, 귀화식물이 19종류로서 귀화율은 5.6%, 도시화지수는 6.8%로 나타났다.
