To investigate the vegetation structure of mountain ridge from Bubong to Poamsan, 16plots$(400m^2)$ set up with random sampling method were surveyed. Two groups of Quercus mongolica-Pinus densiflora community, Quercus variabilis-Pinus densiflora-Quercus mongolica community were classified by cluster analysis. Quercus mongolica was a major woody plant species in the ridge area from Bubong to Poamsan, and Quercus variabilis and Pinus densiflora were partly occupied in lower elevations. High positive correlations were proved between Lespedeza maximowixcii and Pinus koraiensis, Fraxinus sieboldiana and Rhododendron mucronulatum, Acer mono and Weigela subsessilis, and relatively high negative correlations were proved between Symplocos chinensis for. pilosa and Fraxinus sieboldiana, Rhododendron mucronulatum. Species diversity(H') of investigated groups were ranged from $0.9066\~1.0821$, and it was relatively low value compared to that of mountain ridge area of other national parks.

The purpose of this study was to analyze the community structure of forest vegetation in Mt. Geumsusan belong to Woraksan National Park for providing basic information of ecological management. Data were collected by 41 plots from June to November in 2016 using Z-M phytosociology method, which was analyzed with vegetation types, mean importance value and coincidence method. As the results, the forest vegetation was classified into Quercus mongolica community group including Cornus controversa community, Castanea crenata community(Vegetation unit 3), Quercus variabilis community(Vegetation unit 4) and Q. mongolica community(Vegetation unit 5). C. controversa community was divided into two groups such as Ulmus davidiana var. japonica group(Vegetation unit 1) and Parthenocissus tricuspidata group(Vegetation unit 2). Mean importance percentage of vegetation unit 1 was showing Fraxinus rhynchophylla 14.9%, Morus bombycis 8.7% and Acer pictum subsp. mono 8.3%, that of unit 2 was Larix kaempferi 23.2%, C. controversa 20.1% and P. tricuspidata 6.5%, that of unit 3 was Q. mongolica 15.8%, C. crenata 13.4% and F. rhynchophylla 9.8%, that of unit 4 was Q. mongolica 26.6%, Q. variabilis 20.8% and Pinus densiflora 16.7%, that of unit 5 was Q. mongolica 48.3%, Styrax obassia 7.5%, F. rhynchophylla 5.3% in the order, respectively. Each vegetation unit was classified with dependance on environmental factors as 700m of altitude, $20^{\circ}$ of slope degree, middle slope of topography, 20% of bare rock, 30 taxa of present species, 80% of tree layer coverage rate and 20m of tree layer height. In conclusion, it was preferentially considered that development of peculiar and specific management methods with vegetation unit classified above should be needed for ecological and sustainable forest vegetation management.

This study was conducted to suggest vegetation management plan for Gugok landscape maintenance and improvement by deducing the vegetation landscape factors inherent in Yongha Gugok and understanding vegetation structure through the investigate of existing vegetation and plant community structure of Yongha valley in Woraksan National Park. There were broad and flat rocks, natural layered stones, clear water, light stones, stream, valleys, waterfalls, Pinus densiflora and Acer pseudosieboldianum as a result of deducing natural factors on poetry. There were P. densiflora and A. pseudosieboldianum appeared as one of main vegetation landscape elements. The actual vegetation analysis results were as followed. The natural vegetation occupied 67.5% and it was classified as P. densiflora community, Quercus variabilis community, Q. variabilis-P. densiflora community, Q. variabilis-Q. serrata community, Q. serrata community, Q. mongolica community, Q. mongolica-P. densiflora community, Deciduous broad-leaved tree community. The artificial vegetation(18.7%) was classified as Q. serrata community-Larix kaempferi community, Q. mongolica- Castanea crenata community, L. kaempferi community, L. kaempferi-C. crenata community, fruticeta, L. kaempferi-Q. mongolica community. The grassland area(2.0%) was classified as Miscanthus sinensis community, Phragmites communis community, and other areas were classified as landscape tree planting area, farm, orchard, residential area. The representative vegetation were P. densiflora community, Q. variabilis-Q. serrata community, L. kaempferi community, Deciduous broad-leaved tree community in Yongha Gugok. The species diversity index of Shannon was 0.6274~0.9908 on the whole. Yongha Gugok, as a symbol of succession on confucianism and reverence for nature, should be preserved natural valley landscape being clean and wijungchuksa at the end of Joseon Dynasty and Japanese Colonial era. In this historical and cultural Gugok, vegetation landscape management plan is needed to landscape maintenance with P. densiflora community, density control with L. kaempferi community. And it is considered when natural disasters and artificial damages happened, P. densiflora-oriented vegetation restoration plan should be applied in order to restore.

The objective of the study is to analyze the impact of zone adjustment by comparing the changes from 2011 to 2018 of social and environmental factors such as the special-purpose area, actual construction activities including building development, land use environment, and officially assessed individual land price in the areas released from the National Park Zone during the second National Park Zone adjustment during 2010 to 2011 with the social and environmental factors in the areas that remained in the National Park Zone during the same period. We intended to investigate the problems of the second National Park Zone adjustment and explore alternative implications for the third National Park Zone adjustment. As for the special-purpose area, 80.4% of the released areas were converted to planned, production, and conservation area while 15.6% changed to the agricultural area, and 4.0% remained as the natural environmental conservation area. Regarding the change in building development scale, the average size of construction in the released area since 2011 was $106m^2$ while that in the retained areas was $91m^2$. For the land use environment, the rate of change from the natural area to developed area was 1.9% in the released area and 0.7% in the retained area. The officially assessed individual land price increased by 11,911 won in the released area and 4,413 won in the retained area. Although both areas showed an increase in the land price, the difference of officially assessed individual land prices was about 2.5 times. The problem concerning the private property rights of local residents in the national parks is still a challenge, but the second National Park Zone adjustment has resolved the problem significantly. Accordingly, it is necessary to offer the benefits for the residents in the national park area by analyzing the park zoning and park facility planning to present the rational alternative. It is also necessary to establish a support system that encourages the collaborative cooperation between the park authority and residents and assures that the residents to have pride in the national park.
