To investigate edge vegetation structure and edge species in Kaya Mountain National Park, field survey was executed from July to August, 1989 and the result are as follows. Cantilevered and advancing types of edge vegetation were observed on site, The relative importance values of major species were changed along distance from edge to forest interior and were seemed to be affected by aspect, soil moisture and present tree layer vegetation. Especially, light-oriented species were observed as a codominant species under pine tree canopy due to selective allelopathy effect and thin canopy. Ecological indices according to the distance from edge to forest interior did not show regular pattern, but edge depth was estimated as 15-20m, approximately, Dominant species of edge seemed to be affected by soil moisture rather than altitude and aspect, but floristic similarities seemed to be affected by altitude. Frequency classes of edge species were different by aspect, altitude and physiogra-phical location. Lespedeza maximowiczii, Weigela subsessilis and Fraxinus rhynchophylla showed high frequency class in all environment conditions.

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.

It is very difficult to conduct a tracing survey of a forest fire because the affected area is huge and the topology of the mountain defies access of investigators. As a result, remote sensing technique is used to get consecutive information about the range and ecological change of the affected area. Therefore, this study investigates the change of activity condition of vegetation by getting vegetation index, hinted by the fact that activities of plants decline after the fire.

The vegetation types and distributional characteristics of the forest vegetation on Mt. Ilwol were investigated by the Z-M school method. Geographical distribution of the vegetation was a central/montane(CEMO) type of the Korean Peninsula subtype. The forest was classified into five vegetation units: Artemisio-Quercetum mongolicae (Artemisio-Quercetum typicum subass. nov., Artemsio-Quercetum pinetosum dens~florae subass. nov. ). Lychno-Quercetum mongolicae (Lychno-Quercetum Calamagrostetosum arundinaceae subass. nov.. Lychno-Quercetum ligularetosum f~scherii subass. nov.), Fraxinus rhynchophylla community, Quercus variabilis community and Larix leptolepis afforestation. Species with percentage constance degree more than 61% are Quercus mongolica (89.5%, V), Lespedeza maximowiczii (73.7%, IV), Isodon japonicus(73.7%, IV), Fraxinus rhynchophylla (68.%, IV), Arlemisia stolonifera (65, 8%, IV), etc. Artemisio-Quercetum mongolicae was chiefly distributed on the ridge lines of low altitudes (570~700m) and on the ground with exposed rocks in sloping surface (800~1, 000m). Both Fraxinus sievoldiana and Rhododendrou schlippenbachii of the Artemisio-Quercetum mongolicae showed a predominant condition all over the subtree and shrub layers. Of Artemisio-Quercetum pinetosum densifloraes, Pinus densiflora becomes powerful over the tree layer and, on the other hand, Quercus mongolica over the subtree layer. Lychno-Quercetum mongolicae was distributed somewhat on the humid region of the high altitude area (840~1.200m). Fraxinus rhynchophylla community was chiefly distributed in the vicinity of the ravines. Quereus rariabilis community was distributed at subxeric slope on southeast side of the mountain. Larix leptolepis has been reforested at the ecotone between Artemisio-Quercetum mongolicae and Lychno-Quercetum mongolicae. Percentage cover degrees of the subtree layer In Lychno-Quercetum mongolicae, Quereus rariabilis community and Larix leptolepis afforestation were relatively low, 15.3%, 5% and 2.5%, respectively.The contents of moisutre and organic matter in the soil were much higher in Luchno-Quercetum monogolicae and Larix leptolepis afforestaion than in the other communities. Contents o Ca, Mg, K and the available phosphorus were relaively high compared with forests of the other area. This result seems to be influenced by a forest fire. As the altitude increases, the moisure content in the forest soil also increases.
