The vegetation of Mt. Geum in Namhae-gun Gyeongsangnam-do was investigated by the methodology of the ZM school, from February, 2000 to May, 2002. An actural vegetation map and vegetation table were constructed to understand the distribution of plant community in this area. The vegetation in this study area was classified into 10 communities (Pinus. densiflora, P. thunbergii, Quercus acutissima, Q. serrata, Q. variablis, Q. mongolica, Styrax ja-ponica, Corylopsis coreana, Zelkova serrata and Carpinus tschonoskii) and 1 afforestation (Chamaecyparis obtusa). According to the actual vegetation map, P. thunbergii forest, Q. serrata forest and Q. mongolica forest were found at the southern slope, northern slope and the center region of Mt. Geum, respectively. The forest of P. thunbergii was widely distributed in this area.

This study was intended to suggest the appropriate vegetation management methodology by analyzing phytosociology for ecotourism resources. We carried out the classification and interpretation of the vegetation structure and the analysis of the relationship between communities and environmental conditions in Pocheon valley, Mt. Gaya. The vegetation in Pocheon valley was composed of 5 communities: Pinus densiflora-Quercus mongolica community, Quercus serrata-Quercus variabilis community, Larix kaempferi-Quercus serrata community, Pinus densiflora-Castanea crenata community, and Salix gracilistyla-Phragmites japonica community. The Quercus serrata-Quercus variabilis community was further segmented into two types according to the differences of composition species and location of habitats. The methodologies that satisfy both the use of nature for ecotourism resources and the sustentation of natural vegetation are as follows: - maintenance the present vegetation (dominance species) by strictly avoiding artificial management in the tree layer; - maintenance of the existing vegetation structure through the artificial management of the usual vigorous tree species when the species in the shrub layer grow up to the subtree layer; and - continued artificial management to maintain high balanced diversity and evenness of various species in shrub and herb layers.

We classified the forest type and figured out the ecological characteristics for each of the types in order to provide the basic informations for being induced ecologically efficient forest practice plan by vegetation units in the natural forest of Songnisan. We established the 250 sample points and collected the vegetation data of vertical distribution for each sample. A variety of multivariate statistical methods were applied to classify the forest types. The species diversity index were analyzed to estimate the stability and maturity for forest vegetation in each the type. The types were divided from two to ten clusters by cluster analysis. The appropriate number of clusters was estimated five clusters by indicator species analysis. It was verified through the multiple discriminant analysis that the estimated number of clusters had been suitable. Based on the species composition for each the type, this study site was classified into five forest types: 1) Quercus serrata and 2) mixed mesophytic forest in the valley area, 3) Q. mongolica forest in the main ridge, 4) Pinus densiflora forest in the sub-ridge extending from the main, and 5) Q. variabilis-P. densiflora forest between the sub-ridge and valley. The species diversity index of the pine forest that had been a simple species composition was the lowest while that of the mixed mesophytic forest of which the composition had been diverse was the highest. As the forest vegetation was more varied, the index showed a tendency to increase.

The forest vegetation of Namhae-gun was investigated using the methodology of the Z.-M. school of phytosociology from March, 1998 to September, 2003. The forest vegetation was classified into 12 communities, 11 subcommunities, 5 afforestations as follows : Quercus mongolica community(typical subcommunity, Rhododendron schlippenbachii subcommunity), Ouercus serrata community(typical subcommunity, Acer pseudo-sieboldianum subcommunity), Ouercus variablis community(typical subcommunity, Platycarya strobilacea subcommunity), Quercus acutissima community, Carpinus laxiflora community, Carpinus coreans community, Styrax japonica community, Zelkova serrata community, Corylopsis coreana community, Pinus densiflora community(typical subcommunity, Rhododendron mucronulatum subcommunity, Carpinus laxiflora subcommunity), Pinus thunbergii community(typical subcommunity, Eurya Japonica subcommunity), Rhododendron yedoense var. poukhanense community, Chamaecyparis obtusa afforestation, Alnus firma afforestation, Pinus rigida afforestation, Robinia pseudo-acacia afforestation, Cryptomeria japonica afforestation. The soil pH of the study area was ranged from 4.2 to 5.4, and soil moisture content was strongly related to organic matter content. The Corylopsis coreana community contained the highest soil moisture content, whereas Pinus densiflora community contained the lowest one. The content of organic matter were $15.8\sim19.1%$ in the Quercus mongolica, Carpinus coreans and Ouercus serrata communities, $3.3\sim5.4%$ in the Quercus acutissima, Corylopsis coreana and Pinus thunbergii communities, and $2.8\sim5.6%$ in the Pinus rigida and Cryptomeria japonica afforestation. There is significant correlation among the contents of cations($K^+$, $Ca^{2+}$ and $Mg^{2+}$).

The evergreen broad-leaved forest in Mt. Turyunsan was classified into four plant communities : Carpinus tschonoskii community, Carpinus tschonoskii - Quercus acute community, Quercus acuta community, Neolitisea sericea community. Quercus acuta, which had been appeared as a dominant species in most evergreen broad-leaved forest, was assumed to be succeed from Quercus serrata and Quercus variabilis through Carpinus tschonoskii, and would be succeed to Neolitsea serisea. Carpinus thschonoskii and Quercu serrata were assumed to be competitive with Quercus acuta, Camellia japonica, Neolitsea serisea and, Machilus thunbergii. It was assumed that Quercus acuta had a similiar ecological niche with Camellia japonica. Also it was assumed Neolitsea serisea had a similiar ecological niche with Lozoste lansifolia.

This study was aimed to reduce the period of bed log through the protection of harmful fungi and to investigate the effects of physiologically activating substance on the yield increase of Lentinus edodes. Extracts of Allium fistulosm, Hordeum vulagare var. hexastichon, Lentinus edodes. Daucus carota var. sativa, and Citrus junos were used as a physiologically activating substances. The degree of mycelial growth tested by color change after Benzene - azo - ${\alpha}$ - naphthylamine. One percent extract of Album fistulosm was most highly effective as a physiologically activating substance on mycelial biomass growth of Lentinus edodes. Best effects of application of physiologically activating substance was observed in Quercus variabilis bed logs. These results suggested that supplement with physiologically activating substance to the bed log would be beneficial for the production of Lentinus edodes.

A comparative study on the structure of wood and charcoals was examined by scanning electron microscopy. Four species as Quercus variabilis $B_LUME$, Quercus mongozica $F_ISCH$ , Fraxinus rhynchcphylla $H_ANCE$ and Prunus sargentii $R_EHDER$ were used for this experiment. Cell dimensions of charcoals showed more higher shrinkage than those of wood. Shape of vessels was slightly changed due to become smaller in tangential diameter. Therefore, it was considered that the decrease of charcoal yield was caused by decrease of cell dimensions as well as loss of wood components.
