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.

This study was designed to analyze vegetation units using a phytosociological method and to identify the ecological characteristics of each vegetation unit, for forest vegetation from Misiryeong to Danmokryeong of Baekdudaegan, in which, in total, 150 plots were surveyed during May to October 2016. Using community classification according to phytosociology, the Quercus mongolica community group was classified at the top level of a vegetation hierarchy that was classified into an Abies koreana community and a Carpinus cordata community. The A. koreana community was divided into Thuja koraiensis and A. koreana typical groups. The T. koraiensis group was subdivided into Pinus pumila and Betula chinensis subgroups. The C. cordata community was divided into Sasa borealis and C. cordata typical groups. Thus, this forest vegetation comprised one community group, two communities, four groups, and two subgroups and indicated five vegetation units. After analyzing the correlations among the five vegetation units classified by this plant sociological method and the environmental factors like altitude, bare rock, number of present species, and coverage of tree layer with a coincidence method, the A. koreana community and C. cordata typical group were found to be distributed above 1,000 m in altitude, and the S. borealis group was distributed below 1,000 m in altitude. Except for vegetation unit 1, vegetation units tended to be mainly distributed where there was less than 20% bare rock. There was no typical tendency in the number of species present; vegetation unit 5 showed the most abundance among the vegetation units. Coverage by the tree layer mostly exceeded 60%, except for vegetation unit 1.

This research was to establish the fundamental materials for the preservation and multiple-purpose management of forest vegetation of Dong Hwa Sa area located in the south facing slope of Mt. Pal-Gong. Analysis of forest vegetation of this area was studied by the method of Gentaro Toyohara, based on ZM School method and Pfister. The results obtained were summarized as follows. (1). Forest vegetation in this area divided into mountain forest and valley forest. (2). Mountain forest divided into A. Pinus densiflora community, B. Carpirtus laxiflora community, C. Quercus mongolica community. (3). Valley forest was formed mostly of Zelkova serrata community. (4). Piraus densiflora community divided into 1. Pines densiflora typical group, 2. Pines densiflora-Alnus hirsuta group, 3. Pines densiflora-Ilex macropoda group. (5). Quercus mongolica community divided into 1. Pinus densiflora-Carpinus cordata group, 2. Prunus sargentii-Hydrangea serrata for. acuminata group, (6). Zelkova serrata community divided into 1. Acer mono group, 2. Vine plant group. A vegetation analysis based on concepts and methods developed by Robert, D. Pfister and Gentaro Toyohara was considered to be effective on providing a guiding principle for a multiple-purpose management of forestry and a three-dimensional utilization of forest, but it is not easy for us to utilize such a analysis method because we are not rich in the materials of analysis of vegetation to our forest. Thus, It is necessary that we should collect much materials to various parts of forest in order that may utilize this method of analysis of vegetation.

This study was conducted to investigate forest ecosystem assessment which were widely used in Germany and Austria. The study area, Mt. Teawha, is located at Kwangju, Kyunggi-Do province. The methodology of this study considered the following factors. First forest types were classified accoding to species composition and age of tree layer. Naturalness, diversity and rerenees of each forest type were classified into 5 level. Finally, the forest types were assessed by synthesizing those 3 factors. Qurecus mongolica- and valley forest type over 300m was classified as naturalness 4 and Qurecus accustima, Quercus accusitima and Q. variabilis were as naturalness 3. The plantation types on the lower slope showed the level of naturlness 1 or 2. Diversity was similer to naturalness. But indices were different from each other. In the case of Larix leptolepsis plantations, naturalness indicated 1, while diversity showed 3. The valley forest type, wet forest and forest edge were classified into rare forest type. It was concluded that this method could be more efficient method comparing with existing method for assessment of naturality and thereby could contribute for biodiversity conservation in Korea.

This study was carried out to classify forest vegetation structure of Mt. Munsu and Mt. Okseok from May to September in 2008 using phytosociological analysis methodology of Z-M school under the purpose of furnishing basic materials for rational and scientific forest management. Total of one hundred five study sites (quadrats) was investigated in the area. Quercus mongolica community group was divided into 5 communities such as Pinus densiflora for. erecta community, Hydrangea serrata for. acuminata community, Salix gracilistyla community, Pinus koraiensis community and Larix kaempferi community. Pinus densiflora for. erecta community was subdivided into Rhododendron micranthum group, Quercus variabilis group and Pinus densiflora for. erecta typical group. Hydrangea serrata for. acuminata community also into Ligularia fischeri group, Deutzia glabrata group (into Juglans mandshurica subgroup, Prunus maackii subgroup and Callicarpa japonica subgroup). Accordingly, the vegetation of the study areas could be described as 1 community group, 5 communities, 5 groups, and 3 subgroups and as 10 units in total. Classified vegetation units were highly correlated with altitude and topography. According the analysis of interspecific association, it was shown as three types which were coincident with differential species and character species on the constancy table.

This study was carried out to understand the spatial distribution and conservation, restoration plan for vegetation in the Hwaeom wetland protected area. Total 29 phytosociological releves consisted of 117 plant species (unidentified species contained) was made during field studies conducted at 2008 and 2013 applying Braun-Branquet method. The collected vegetations were arranged 8 plant communities and thus divided hydric types (Drosera rotundifolia-Eleocharis congesta community, Carex forficula-Molinia japonica community) and xeric types (Miscanthus sinensis community, Rhododendron yedoense var. poukhanense community, Tripterygium regelii community, Carex gifuensis-Quercus mongolica community) under moisture conditions. The hydric types growing in hydric conditions distributed along hollowed out ground or the water channel that have a key qualification to protect. In the wetland protected area, the hydric vegetation types were mostly covered about 3.8% and the xeric types dominating by Miscanthus sinensis were most wildly distributed about 51.5%. Various woody plant species invaded the place. In 2008, invasion plants observed with total 14 species - 8 tree species (227 individual), 6 shrub species (51 individual) and alders (Aluns japonica) found in 2013. We suggested finding out that the sustainable conservation and management in Hwaeom wetland should be setting up plan focused on activity and variability such as continuous monitoring (changing vegetation types, spatial distribution, invasion plants) and zonation management (core zone, buffer zone, transition zone).
