Abstract
This study was carried out to investigate the environment factors including community structure and soil characteristics in the wild habitats of Cephalotaxus koreana, and offers the basic information for habitats conservation and restoration. Most of the wild habitats were located at altitudes between 148~835 m with inclinations ranged as 12~32°. The average soil pH was 4.7~5.9, soil organic matter was 5.72~15.99%, cation exchange capacity was 14.1~19.9 cmolc/㎏-1 and exchangeable K+, Ca2+, Mg2+ was 0.25~0.48 cmolc/㎏, 0.79~6.68 cmolc/㎏, 0.31~1.73 cmolc/㎏, respectively. The dominant species of tree layer were found to be dominated by Quercus dentata in Jekbo-san (C1), Acer pictum in Bogae-san (C2), Acer pseudosieboldianum in Geumwon-san (C3), Q. serrata in Jiri-san (C4), Zelkova serrata in Baegun-san (C5), and Q. acutissima in Duryun-san (C6). The Species diversity (H’) was 0.854~1.234, evenness (J’) was 0.654~0.993, and dominance (D) was found to be 0.067~0.346. Correlation coefficients analysis based on environmental factors, community structure and value of species diversity shows that growth of Cephalotaxus koreana is correlated with species diversity and evenness. This result show that Cephalotaxus koreana habitats located in mature stands.
