  • This study was conducted to classify community and verify vegetation structure of Picea jezoensis community in subalpine zone of Mt. Kyebang, Mt. Jiri, Mt. Deogyu, 39 releves set up and was carried out to analyze ordination. P. jezoensis Community was classified into Acer ukurunduense subcommunity, Quercus mongolica subcommunity, Syringa reticulata var. mandshurica subcommunity and P. jezoensis typical subcommunity. The order of important value of the forest community with DBH 2cm above plants was P. jezoensis (89.22), Acer komarovii (30.50), Abies koreana (18.81), Rhododendron schlippenbachii (18.10), Sorbus commixta (17.19), Betula ermanii (16.89), Pinus koraiensis (16.80), Taxus cuspidata (12.45), Acer ukurunduense (11.73). The DBH analysis suggests that P. jezoensis will maintain dominant position.

  • To investigate the vegetation structure of mountain ridge from Jeongryongchi to Bokseongiiae in Baetdudaegan, thirty few sites(size 500$m^2$) were set up and surveyed. By using TWINSPAN and DCA technique, the Plants community was divided into four groups, those are Pinus densiflora - P. rigida community, P. denisiflora community, P. densiflora -Larix leptolepis community, Quercus mongolica cummunity. P densiflora is turned out as a dominant woody species in the ridge area. Diversity index of the species in ridge area which is semi mountainous one, is lower than one of mountainous ridge area.

  • To investigate vegetation structure and succession of forest in the Deokyusan National Park, field survey was performed from July to September, 1992 and the results were as follows; The forest vegetation of Deokyusan National Park was classified into four communities by the factor of altitude. The successional trends of tree species by DCA ordination seem to be from Pinus densiflora to Carpinus laxiflora and Betula schmiatii and also, Quercus spp. through Cornus walter and Platycarya strobilacea to Q. mongolica, Abies holophylla and Taxus cuspidata. The diversity indices seemed to be affected by the factors of altitude. Especially, evenness showed several difference according to altitude. Comparing vegetation structure of lower layer for the recess system and one others, more number of species and species diversity were observed.

  • The purpose of this study was to identify remained real state of groves of enclosed village in human settlement circle. That was practiced in case of Chinan-Gun region which traditional elements had well been conservated. 48 village groves were found by site survey, reference and interview in Chinan-Gun region. 27 groves of 48 village groves were clarified as complementing village grove by classification of grove character. It was identified through survey that many were partially destructed by development and human use. The results of this study showed general, socio-behavioral characteristics, characteristics of forest state and vegetation structure of complementing village groves. Length, area, form, type, motive, location, relationship of those were analyzed to identify general characteristics. Facilities, human behavior and ownership of those were analyzed to identify socio-behavoral characteristics. Dominent species, appearing rate, height, width, density and biodiversity of upper trees were analyzed to identify forest state and vegetation structure. Interrelation of each factor were analiged and comparative review with previous studies was achieved.

  • In order to study the characteristics of vegetation structure in Gundal mountain, we investigated forest community using belt transect method at 30 sites in Gundal mountain. As the result of important value' calculation on over DBH 2cm, Pinus densiflora (56.8), Quercus mongolica (48.5), Pinus rigida(41.4), Castanea crenata (22.3), Quercus variabilis (22.3), Carpinus laxiflora (16.9), Quercus aliena (11.3), Sorbus alnifolia (8.6), and Quercus acutissima (8.5) were in the order of important value. According to the ordination analysis of Gundal mountain forest, Quercus mongolica was found in north face and high of mountain. Carpinus laxiflora was found in north face steep slope and middle of mountain. As DBH analysis, the study community will be dominated by Quercus species. The correlation between the forest community and environment factor could be thought as distinction by soil nutrition etc., but we need more study about environment factors.

  • The purpose of this study was to identify remained real state of the village groves in human settlement circle. That was practiced in case of Chinan-Gun region which traditional elements had well been conserved. 33 village groves were found by site survey, reference and interview in Chinan-Gun region. 31 of 51 village groves were clarified as complementing village grove by classification of grove character. It was identified through survey that many were partially destructed by development and human overuse. The results of this study showed general, socio-behavioral characteristics, characteristics of forest state and vegetation structure of village groves in Chinan-Gun region. Length, area, form, type, motive, location, relationship of those were analyzed to identify general characteristics. Facilities, human behavior and ownership of those were analyzed to identify socio-behavioral characteristics. Principal dominant species and appearing rate, height, width, density of those, species diversity of groves were analyzed to identify forest state and vegetation structure. Interrelation between each factor were analyzed and comparative review with previous studies was achieved.

  • When the data from the artificial satellite is analyzed, recent years it is perceived to vegetation index using BRF(Bi-directional Reflectance Factor) of the observation target. To make the BRF models, it is important to measure the 3D structure of the observation target actually. In this study, it is proposed to the observation technique by using multi-angle stereo pair image, and shown the observation result in grassland area. Also, our team has been operating the radio controlled helicopter which can fly over the tall forest canopy and it can be equipped the measurement system.
