  • Vegetation structure of Seokseong fortress in Buyeo-Gun was investigated to suggest a desirable management proposal. Communities by phytosociological method were classified into Pinus rigida-Pinus densiflora community and Quercus variabilis community. The importance value of Pinus rigida, Pinus densiflora, Quercus variabilis, Pinus thunbergii, and Quercus acutissima were 127.06, 70.29, 69.63, 12.39 and 8.57. According to breast diameter analysis results, it is expected that the importance value of Pinus rigida, Pinus densiflora, and Quercus variabilis will be continuously increased. It should be prepared that vegetation management plan over the castle wall should be considered before the repair or restoration of castle wall. Vegetation management around castle wall should be carried out according to the mid or long-term plan and it would be needed to consider the gradual changes from planted Pinus rigida to the historical vegetation of Pinus densiflora.

  • The present study was undertaken to classify and describe the oak (Quercus spp). forests on Mts. Kaya, Bisul, Unmun and Kaji in southern Kyongpook Province, Korea by using a reciprocal averaging method (RA ordination) and the methodology of the ZM school of phytosociology. A temporary vegetation table was prepared by the RA ordination. The diagnostic species of the Quercus forests derived from the ordination were compared with the characteristic and differential species of the existing phytosociological vegetation units of the other mountainous areas of Korea. As a result, the forest vegetation was classified into the next vegetation units: Fagetea crenatae Miyawaki et al. 1968; Acero-Quercetalia mongolicae Song 1988; Rhododendro-Qurcion mongolicae Song 1988, 1. Stephanandra incisa-Quercus mongolica community 1-1 Sasa borealis subcommunity, 1-2 Disporum smilacinum subcommunity; Lespedezo-Quercion serratae Takeda et al. 1994, 2. Spodiopogon sibiricus-Quercus serrata community. The Rhododendro-Qurcion mongolicae and the Lespedezo-Quercion serratae correspond to the cool-temperate forests of the northern type and the southen type (Honda 1922), respectively, in the Korean Peninsula. Also some phytosociological problems in Korea were discussed here in detail from the floristic viewpoint in the present study.

  • The present study was undertaken to classify and describe the Quercus mongolica forest on Mt. Sobaek (36°50'∼ 37°07'N, 128°25'∼ 128°35'E), Korea by a reciprocal averaging methol (RA ordination) and the methodology of the ZM school of phytosociology. Atemporal vegetation tabel was prepared by the RA ordination. As a result it showed that the RA ordination on the first axis is very applicable for selecting the character and differential species of vegetation units of the Quercus mongolica forest. The phytosociological investigations were carried out in 34 stands on the mountain. The field data obtained were classified by the tabel comparison method. For the establishment of new vegetation units, the floristic composition of the Quercus mongolica forest was compared with those of the other vegetation units of the Mt. Sobaek, Considering the candidates of the character and differential species derived from RA ordination. As the result, the forest vegetation was classified into the following vegetation units; Fagetea crenatae Miyawaki et al. 1968 Acero-Quercetalia mongolicas Song 1988 em. Takeda et al.1994 Lindero-Quercetalia mongolicae Kim 1990 1. Lindero-Quercetum mongolicae assoc. nov. 1-1. quercetosum serratae subassoc. nov 1-2. typicum subassoc. nov. Rhododendro-Qurcion mongolicas Song 1988 em. Takeda et al. 1994. It is inferred that the Lindero-Quercion mongolicae and the Rhododendro-Quercion mongolicae corresponded to the cool-temperate forests of central and northern areas, respectively, in Korean Peninsula. Syntaxonomical synonyms were also rearranged based on the result of the present study. On the other hand, the RA ordination of stands and species on the first and second axes revealed some environmental gradients such as altitute, human impact and species richness between the vegetation units. However, the RA ordinations is considered to be less indicative for the gradients of the lower vegetation units than association. With the present study. some phytosociological problems in Korea were discussed here in detail from the floristic viewpoint.

  • Pine (Pinus densiflora) forests of 58 sites on the ridge of the Baekdudaegan, South Korea were classified by applying the phytosociological method and TWINSPAN. The floristic composition and life-form characteristics of the vegetation types analyzed and documented. The vegetation types were classified into five groups including four groups of Carex humilis var nana type and one group of Abies koreana-Sasa borealis type. Compositae was the most diverse family (26 species), Liliaceae (21 species), Rosaceae (18 species) and Betulaceae (11 species) whereas 27 families were represented by only one species. Taxonomically, Compositae was the most diverse (17 genera), Liliaceae and Rosaceae(12 genera) whereas 41 families were represented by only one genus. The Fagaceae was the most important family in total coverage (19.0) and followed Pinaceae (16.7) and Ericaceae (15.1). Five families such as Compositae, Liliaceae, Rosaceae, Betulaceae, and Umbelliferae contributed little to total coverage, although represented by numerous species. In the correlation between species richness and life forms, the species richness was highly correlated with growth and disseminule forms. In general, the correlation coefficients between life forms represented lower values than those between species richness and life-forms.
