초록

본 연구는 무등산국립공원 담양권역의 전체 식물상 및 특기 할만한 식물의 분포를 파악하고 생태계교란 야생식물의 유입요인 및 관리방안을 모색해보기 위해 수행되었다. 조사는 2019년 5월부터 2020년 10월까지 총 8차례에 걸쳐 실시되었다. 무등산국립공원 담양권역의 식물상은 107과 349속 531종 57변종 5아종 10품종 총 603 분류군이 분포하는 것으로 확인하였다. 이는 우리나라 관속식물 총 4,881 분류군의 약 12.33%로 나타났다. 무등산국립공원 담양권역에서 출현한 희귀식물은 총 15 분류군이 관찰되었다. 멸종위기종(CR)은 목련, 위기종(EN)은 댕강나무 등이 출현하였다. 취약종(VU)은 개박하, 나도옥잠화, 땅나리 그리고 주목이 관찰되었다. 무등산국립공원 담양권역의 식물구계학적 특정식물은 50과 73속 81종 3변종 1아종으로 총 85 분류군이 출현하였다. V등급은 승마 등 3분류군, IV등급은 선주름잎, 고로쇠나무, 털조장나무 등 5분류군, III등급은 청시닥나무, 산황나무 등이 관찰되었고, 특산식물은 노각나무, 닥나무, 각시서덜취, 백운산원추리, 병꽃나무, 검팽나무, 진범 등 총 13 분류군으로 파악되었다. 무등산국립공원 담양권역에서 출현한 귀화식물은 미국자리공, 방가지똥 등 16과 36속 45종 총 45 분류군으로 관찰되었고, 귀화율은 7.46%로 나타났으며, 도시화지수는 14.01%로 계산되었다. 생태계교란 야생식물은 돼지풀, 애기수영, 도깨비가지, 및 양미역취 총 4 분류군이 관찰되었다. 신선대억새평전에 생육하는 생태계교란 야생식물인 애기수영에 대한 장기적인 모니터링이 요구되고, 특히 물리적이고 생물학적인 방제가 지속되어야 할 것이다.

This study was investigated to find out the distribution of flora and remarkable plants and factors and management measures for influx of wild disturbed plants in the Damyang area of Mudeungsan National Park. The field survey was carried out 8 times from May 2019 to October 2020. First of all, in the Damyang area of Mudeungsan National Park, a total of 603 taxa in 107 families, 349 genera, 531 species, 57 varieties, 5 subspecies and 10 forms. This result was found to be about 12.33% of the total 4,881 taxa of vascular plants in Korea. In addition, Rare plants were classified as 15 taxa. Floristic special and Korean endemic plants were identified as 85 taxa and 13 taxa, respectively. Lastly, the naturalized plants that appeared in the Damyang area of Mudeungsan National Park were observed in 45 taxa with 45 species of 16 families and 36 genera. Moreover the naturalization rate was 7.46% and the urbanization index was calculated to be 14.01%. The wild disturbed plants were found in a total of 4 taxa. Especially, a sheep sorrel(Rumex acetosella) was focused on managing for physica and biological control at Sinseondae Eoksaepyungjeon.
