경남 진주시 귀곡섬의 식물상에 관한 연구

초록

This study was conducted to analyze the flora of Guigokseom where forest welfare facilities such as riverside parks and botanical gardens are planned to be built in the future, and to provide basic data for establishing a vegetation management plan to enhance biodiversity and landscape functions. The field survey was conducted 9 times from April to November 2025. The vascular plants were identified as a total 290 taxa of 92 family, 213 genera, 262 species, 3 hybrida, 5 subspecies, 17 varieties, and 3 forms. The flora was counted as 13 taxa of pteridophytes, 11 taxa of gymnosperms, 205 taxa of dicotyledons, and 61 taxa of monocotyledons. The rare plants designated by the Korea Forest Service were 5 taxa including Iris setosa, Ilex cornuta, Ilex x wadoensis, Forsythia koreana, and Melothria japonica, and 3 taxa including the endemic plants, Ilex x wadoensis, and F. koreana were identified. A total of 21 floristic target species were identified, including Iris setosa as Grade Ⅳ, M. japonica as Grade Ⅲ and Pteris multifida as Grade Ⅰ. Naturalized plants were classified into 23 taxa, including the ecosystem disturbance species, Korean yam, and the naturalization rate was 9.5%. The research site is not accessible to the general public, so the naturalization rate is not high. 6 taxa including Viola grypoceras were identified as biological indicator species designated by the Ministry of Environment. 7 southern plant taxa including P. multifida were identified as climate change adaption species designated by Korea Forest Service. The current vegetation of this study area was divided into a total of 14 types with the largest area as 55.2% of the deciduous broadleaf tree community dominated by Japanese maple and cherry trees.
