Abstract

This study was conducted to investigate the flora of Mt. Seongdeok (Ganghwa-gun) in Korea. From the results of nine field surveys from March 2020 to July 2022, a total of 445 total taxa, representing 397 species, nine subspecies, 35 varieties, two forms and two hybrids were identified, which were placed in 273 genera and 93 families. The plant formation of Mt. Seongdeok is a deciduous broad-leaved and conifer mixed forest, which is common in the middle part of the Korean Peninsula. Most of the mountain is covered by a young secondary forest, which is mainly composed of Quercus ssp. and Pinus ssp. Among them, five taxa were endemic to Korea, one taxon were endangered plant and two taxa were red list plants. The floristic target plants amounted to 27 taxa, specifically one taxon of grade V, four taxa of grade III, seven taxa of grade II, and 15 taxa of grade I. And 43 taxa were northern lineage plants. A total of 46 species of alien plants were identified, with a Naturalized Index of 10.3%, an Urbanization Index of 11.7%, and six plants that disturbed the ecosystem. Our results provide basic data on vascular plants flora, and plant diversity and distributional changes.

본 연구는 성덕산의 관속식물을 밝히고 주요 식물을 조사하였다. 2020년 3월부터 2022년 7월까지 총 9회에 걸쳐 조사한 결과, 관속식물은 93과 273속 397종 9아종 35변종 2품종 2교잡종의 총 445분류군이 확인되었다. 성덕산은 온대 중부지역에 속하고 침엽수와 낙엽활엽수 혼합림으로 산지의 대부분은 소나무류-참나무류가 우점하며, 2차림으로 구성된다. 멸종위기식물은 1분류군, 지역적색목록은 2분류군이었다. 한반도 고유종은 5분류군, 식물구계학적 특정식물은 총 27분류군으로 V등급에 1분류군, III등급에 4분류군, II등급에 7분류군, I등급에 15분류군이 확인되었다. 북방계 식물은 43분류군, 외래식물은 46분류군이며, 귀화율 10.3%, 도시화지수 11.7%로 나타났다. 생태계교란식물은 6분류군이 확인되었다. 본 연구는 관속식물의 분포 자료로써 식물다양성 및 분포변화의 정보로 활용될 것으로 판단된다.
