가시오갈피(Acanthopanax senticosus)의 자생지 환경특성

This study intended to investigate environmental factors including soil and vegetation in order to understand the environmental and ecological characteristics of 4 different habitats of Acanthopanax senticosus. These habitats, according to investigations, are mostly located at elevation of 674 m to 1,242 m with angles of inclination ranging from 3 degree to 36 degrees. A total of 81 vascular plants are identified in 5 quadrates of 4 habitats. The importance value of Acanthopanax senticosus is 22.9%, and 5 highly ranked species such as Deutzia uniflora (18.1%), Deutzia glabrata (10.3%), Syringa patula var. kamibaysii (6.7%), Weigela subsessilis (5.6%) and Euonymus macropterus (5.1%) are considered to be an affinity with Acanthopanax senticosus in their habitats. The dominance species of the four habitats are represented as Comus controversa (33.8%) in the tree layer (T1), and Actinidia arguta (17.1%), Acer tegmentosum (13.8%) in the subtree layer (T2), and Astilboides tabularis (21.4%), Dryopteris crassirhizoma (11.0%) and Polystichum tripteron (6.7%) in the herbaceous layer (H). The degree of their average species diversity is 1.25, and that of dominance and evenness are 0.08 and 0.89, respectively. The average field capacity of soil is 32.1 %, soil pH is 5.98, and organic matter is 18.21%. Correlation coefficients analysis based on environmental factors shows that the negative correlated in coverage of Acanthopanax senticoslls-coverage of tree and subtree layer.
