Abstract
This is a study intended to investigate the environmental factors including vegetation and soil in order to better understand the environmental and ecological characteristics of four different habitats of Pulsatilla tongkangensis(Mt. Baekun, Maha-ri, Kyulam-ri and Mt. Deokhang). These habitats, according to investigations, are mostly located on the slopes of mountains facing northwest at an altitude of 220m to 772m above sea level with angles of inclination ranging from 41 degree to 85 degree. A total of 27 vascular plant taxa are identified in ten quadrates of the four habitats. The importance value of these plants is as follows: Pulsatilla tongkangensis is 9.65%; Carex humilis var. nana 28.93%; Potentilla dickinsii 16.55%; Mukdenia rossii 7.09%; Peucedanum terebinthaceum and Eragrostis ferruginea 4.55%; and Vicia venosa var. albiflora 3.90%. The importance value of these six species is high, so they are at affinity with P. tongkangensis m their habitats. The degree of their average species diversity is 0.75, and that of dominance and evenness 0.24 and 0.85, respectively. Their average field capacity of soil is 19.05%, organic matter 10.51%, and soil pH is 7.43, which are similar among their habitats.
