광덕산(천안·아산시) 관속식물상의다양성: 생태학적, 보존학적중요성 = Vascular plant diversity of Gwangdeoksan Mountain (Cheonan-Asan, Korea): insights into ecological and conservation importance

국문 초록 (Abstract)

광덕산은 충청남도 천안시와 아산시의 경계에 위치한, 이 일대에서는 가장 높은 산이다. 본 연구에서는 2015년 4월부터 2017년 10월까지 총 20회에 걸쳐 광덕산의 관속식물상을 조사하여, 97과 287속 428종 9아종 30변종 1품종의 총 468분류군을 확인하였다. 이 중 특산식물, 식물구계학적특정식물, 국외반출승인대상종, 희귀식물 및 멸종위기야생식물, 그리고 외래식물 및 생태계교란식물에 해당하는 58과 112속 129분류군이 주요식물로 조사되었다. 광덕산의 식물상은 크게 남동방면, 남서방면, 북방면, 정상부의 4개 구역으로 구분되었으며, 각 구역별로 분포하는 식물상이 뚜렷이 구분되었다. 광덕산의 식물상에 대한 본 조사 결과와 이전의 조사 결과를 종합하여 볼 때, 광덕산은 식물구계학적으로 중요한 의미가 있다고 생각되어 보전 및 연 구가치가 큰 것으로 판단된다.

Gwangdeoksan Mountain (699.3 m) is the highest border mountain between the two cities of Chungcheongnamdo Province, Cheonan and Asan, Korea. In this study, we investigated the flora of Gwangdeoksan Mt. from April of 2015 to October of 2017. Through 20 independent field investigations, we identified and tallied a total of 428 species, 9 subspecies, 30 varieties, and a forma in 287 genera and 97 families. Of a total of 468 taxa, 128 taxa in 112 genera and 58 families were found to be Korean endemic species (7 taxa), floristic regional indicator species (45 taxa), rare or endangered species (3 taxa), species subject to the approval of outbound transfer (73 taxa), and alien or ecosystem disturbing species (32 taxa). The flora of Gwangdeoksan Mt. can be divided into four distinct floristic subregions, with higher diversity in the north-facing subregion. The complex flora of Gwangdeoksan Mt., emerging at the edge of two floristic regions of the Korean peninsula, may represent a significant conservation priority and a topic for future ecological and geographical studies.
