Abstract

This study was to analyze vegetation and soil characteristic, and ordination of Bupleurum euphorbioides community located in Mt. Seorak area, Mt. Sobaek area, and Mt. South Deogyu area. Bupleurum euphorbioides community was classified into Carex lanceolata subcommunity and Chrysanthemum zawadskii var. alpinum subcommunity, and Chrysanthemum zawadskii var. alpinum subcommunity was classified into Calamagrostis arundinacea and Carex breviculmis group. In the study sites, soil organic matter, nitrogen, available phosphorous, changeable potassium, changeable calcium, changeable magnesium concentration, cation exchange capacity, and soil pH were ranged from 9.0~15.2%, 0.32~0.47%, 3.0~8.6ppm, 0.3~0.9me/100g, 0.5~1.5me/100g, 0.2~0.6me/100g, 11.4~16.1me/100g, and 4.3~4.6, respectively. And, soil texture was sandy loam or loam. The Carex breviculmis group of Chrysanthemum zawadskii var. alpinum subcommunity was found in area of high elevation and had high exchangeable K, Ca, and Mg concentration. The Calamagrostis arundinacea group of Chrysanthemum zawadskii var.alpinum subcommunity was found in area of low elevation and had lower exchangeable K, Ca, and Mg concentration than in the other subcommunity. The Carex lanceolata subcommunity was found in area of medium elevation and had medium exchangeable K, Ca, and Mg concentration. The Carex lanceolata subcommunity was located in a path of top the mountain peak, and has been destroyed. We need any action to protect the subcommunity.
