한국에 있어 팥배나무 자생임지의 식생조성과 구조 = Vegetation Composition and Structure of Sorbus alnifolia - Natived Forests in South Korea

다국어 초록 (Multilingual Abstract)

Sorbus alnifolia - natived forest sites were studied in South Korea. The objectives of this study were to classify vegetation types of S. alnifolia - natived forests(SANF) and to analyze its ecological characteristics. Thirteen SANF sites were sampled, and three hundred and fifty releves collected with 10m × 10m plots. Data were analyzed using in combination with Two-Way Indicator Species Analysis(TWINSPAN) and Phytosociological procedures. Two vegetation types of Quercus serrata - Q. acutissima(VT Ⅰ) and Carex ciliato-marginata - Rhododendron schlippenbachii(VT Ⅱ) were identified and six vegetation units accmpanied. SANF exhibits a pattern of weak dominance, meaning that no shingle species han an importance value greater 25%. Diversity indices indicate that VT Ⅰ were less diverse than VT Ⅱ and its scores ranged from 1.68 to 2.17. Constancy classes diagram shows that the higher species(≥Ⅱ) have only 0.9% and that most species occurred were rare and had low abundances. In correlation between tree species, it was found positive correlation between S. alnifloa and introduced tree species such as R pseudo-acacia and Castanea crenata on the level of 1% and Alnus firma, A. hirsuta, and Pinus koraiensis, 5% respectively.
