  • Mt. Kumjeong is located in south-eastern part of the Korean Peninsular($129^{\circ}$01' to $129^{\circ}$05' E, $35^{\circ}$03' to $35^{\circ}$17' N) and the altitude of the summit is 802 meter. In order to find out the vegetation units which made it possible to classify subtropical forest and south-temperate forest, Mt. Kumjeong (which is located in a border of between subtropical forest and south-temperate forest) was selected as a study area. The primary result of actual vegetation analysis in Mt. Kumjeong based upon the vegetation community analysis methods by the ZM-school, and the relationships between vegetation community and two parameters(altitude, topography) analyzed by using coincidence analysis method were summarized as followings. 1. Based upon analytic methods of the vegetation community by the ZM-schools, the primary analytic result of the analysis of vegetation community in Mt. Kumjeong was divided into 10 communities, 9 groups, 2 subgroups. 2. Eurya japonica group of Pinus densiflora community out of 16 vegetation units was thought as a indicator vegetation group which made it possible to border subtropical forest and south-temperate forest. 3. Natural regeneration of Stewartia koreana group was thought to be difficult because seedling and sapling was rarely showed, 4. In relationship between vegetation units and altitude, Carpinus tschonoskii community, Quercus variabilis community, Quercus serrata community, Wisteria floribunda community,. Eurya japonica group of Pinus densiflora community, Pinus thunbergii community mainly distributed below altitude 500 meter, and Quercus mongolica community, Typical group of Pinus densiflora community, Quercus dentata community, Carpinus coreana community, Quercus acutissima community mainly distributed above altitude 500 meter. 5. In relationship between vegetation units and topography, Carpinus tschonoskii community, Quercus variabilis community, Quercus serrata community, Wisteria floribunda community,. Eurya japonica group of Pinus densiflora community distributed below middle slope, Quercus mongolica community, Typical group of Pinus densifiora community, Quercus dentata community, Carpinus coreana community, Pinus thunbergii community Quercus acutissima communily clistributed above midclle slope.

  • This study was carried out to survey and analyze the transition of landscape plants on an apartment complexes in the 1990's and 2000's. The results are summarized as follows; The ratio of landscape area was increased from 30.0% to 34.7%. The number of trees per 100 square meter decreased from 22.5 to 15.7. The number of shrub per 10 square meter increased from 19.3 to 38.7. Species of Evergreen tree were increased 21 to 39. The species that a lot of use continuously were Pinus densiflora, Pinus strobus and Taxus cuspidata. The species that increase use were Abies holophylla and Pinus densiflora for. multicaulis. The species that decrease use exceedingly, were Pinus parviflora, Juniperus chinensis, Pinus koraiensis and Thuja orientalis. The species that do not use were Cedrus deodara. Species of deciduous tree were increased 42 to 68. The species that a lot of use continuously were Zelkova serrata, Acer palmatum, Diospyros kaki, Prunus armeniaca and Prunus yedoensis. The species that increase use were Lagerstroemia indica, Chionanthus retusa, Cornus officinalis, Styrax japonica, Sorbus alnifolia, Prunus mume, Cercidiphyllum japonicum, Acer triflorum, Prunus sargentii, Chaenomeles sinensis and Cornus kousa. The species that decrease use exceedingly, were Acer buergerianum, Sophora japonica, Malus spp., Ginkgo biloba, Zizyphus jujuba var. inermis, Platanus orientalis and Albizzia julibrissin. The species that do not use were Liriodendron tulipifera, Acer saccharinum, Ailanthus altissima and Paulownia coreana. Species of shrub were incresed 39 to 65. The species that a lot of use continuously were Buxus koreana, Rhododendron schlippenbachii for. albiflorum, Rhododendron schlippenbachii, Syringa dilatata and Euonymus japonica. The species that increase use were Rhododendron indicum, Ilex serrata, Spiraea prunifolia var. simpliciflora, Taxus cuspidata var. nana, Kerria japonica, Rhododendron yedoense var. poukhanense, Euonymus alatus, Sorbaria sorbifolia var. stellipila, Nandina domestica, Cornus alba, Hydrangea serrata for. acuminata, Prunus tomentosa, Deutzia parviflora and Pyracantha angustifolia. The species that decrease use exceedingly, were Hibiscus syriacus, Rosa multiflora var. platyphylla, Chaenomeles lagenaria and Rosa spp. The species that do not use were Juniperus chinensis var. sargentii, Jasminum nudiflorum and Sasa borealis.

  • This study was executed to analyze the user's impact on vegetation structure changes and user's psychology in Odongdo Island of Hallyo-Haesang National Park. Five sites were sampled for vegetation structure changes vi the study area according to the extent of impact observed. Also user's psychology was studied through questionnaire with the visitors and 366 answers were collected at random sampling in May, 1986. Evergreen broad-leaved forest, i.e. Machilus thunbergii, Cinnamomum camphora, and Camellia japonica forest, took possession of 32.5% (3.91ha) of total forest area when condisering the actual vegetation. Camellia japonica community covered 40.0% (4.72ha) and Sasa coreana community took possession of 41.8% (5.02ha). The area of environmental impact grade 3 and 4 area covered 44.3% of total forest area and it should be restored because self-repair seemed to be impossible. The evergreen broad-leaved forest was destoryed seriously with no younger trees in middle and lower layers by overuse impact and would be bared soon. So the preservation of autochthonous flora is required by the control of the number of users. It was shown that most of visitors come on holidays and Sunday and places which were favorably impressed were shown as the area of showing the sea and Camellia forest. Overall levels of satisfaction was comparatively low, consequently 55% of visitors were satisfied. This level of satisfaction was associated with number of users, landscape of forest and number of facilities.
