초록

This study was investigated the vascular plants of Hangjeukbong to Jungbong in Mt. Deoguysan National Park, from March to September, 2014. Vascular plants in this area were summarized as 187 taxa, including 52 families, 126 genera, 168 species, 2 subspecies and 17 varieties. Among the recorded taxa, Korean endemic plants were 11 species and the rare and endangered plants designated by Korea Forest Service were 14 taxa comprising 1 endangered species(EN), 5 taxa of vulnerable(VU), 7 taxa of least concern and 1 data deficient(DD). The floristic regional indicator plants were 60 taxa including 1 species in grade Ⅴ, 3 taxa in grade Ⅳ, 12 taxa in grade Ⅲ. The life form spectra was G-R5-D4-e type. It is considered what the ratio of chamaephytes(1.6%) and phanerophytes(35.8%) is lower than that of geophytes(27.3%) and hemicryptophytes(26.7%) is needed to adopt low ambient temperature condition in subalpine. Threatened plants for climate change were 8 taxa including 7 taxa of northern plants such as Taxus cuspidata, Abies koreana, Picea jezoensis, Aruncus dioicus var. kamtschaticus, Sorbus commixta, Acer ukurunduense and Smilacina bicolor. It was considered that vulnerable to microclimate subalpine plants require long-term conservation of management and measure according to monitoring.
