  • This research was initiated to investigate the revegetation characteristics under seedling types of native woody plants on a disturbed slope. 4 different seedling types of woody plants (control, unit seedling plot, nature seedling plot, pot seedling plot) with the same woody plants (Rhus chinensis Mill, Albizzia julibrissin Duraz., Quercus acutissima Carr., Pinus densiflora S. et Z.) were treated with 3 replications on the experimental disturbed slope. Data such as the died number of native woody plants, growth height and visual quality were analyzed. The died number of plants were high in unit seedling plot when compared to the rest plots of seedling types. From the standpoint of died plant species, the died number were high in Rhus chinensis and Albizzia julibrissin whereas the died number were low in Quercus acutissima and Pinus densiflora. That's because we used 1-year old seedlings of Rhus chinensis and Albizzia julibrissin and 3-year old seedling Quercus acutissima and Pinus densiflora. This result indicated that the died reason of native woody seedling was not species but seedling age. Both growth height and visual quality were ranked first in the pot seedling plot, second in the nature seedling plot, third in the unit seedling plot, and last in the control plot, respectively. However, the difference of both growth height and visual quality in each seedling plot was not observed on the 11 months after planting. Especially, the main reason of low rooting and growth value in the unit seedling plot was due to wooven fabric outer crust of pot that obstruct seedling rooting into the soil. We concluded that pot seedling of native woody plants was effective in the viewpoint of the ecological disturbed slope revegetation.

  • This study showed the current plantation of woody landscape plants of 42 school gardens in Daejeon metropolitan city. The ratio between evergreen tree and deciduous tree was 67% to 33%. The ratio between evergreen shrub and deciduous shrub was 48% to 52%. Also, 161 kinds of woody species were found; evergreen tree was 21 species, deciduous tree was 67 species, evergreen shrub was 16 species, deciduous shrub was 44 species, and vine and the others were 13 species. The proportion of native woody species was 61% (98 out of 161 species). 110 species were planted at the front garden area. In the mid-garden, 77 kinds of woody species were found. In the side garden, 95 kinds of woody species were found. In the rear garden, 92 kinds of woody species were found. The surrounding of play ground and outer area were planted 82 species. The first ranked evergreen tree was Juniperus chinensis‘Kaizuka’. And Deciduous tree, evergreen shrub, deciduous shrub, and vine showed Gingko biloba, Buxus microphylla var. koreana, Hibiscus syriacus, Wisteria floribunda, respectively. The school symbol of tree and flower was planted in 41 schools. The first rank plants of school symbol tree and flower were Pinus densiflora, Forsythia koreana and Rosa spp. Plant nameplate was found at 22 schools. The plant nameplate was used for 1∼10 species at 17 schools. In conclusion, plantation of landscape trees should be considered characteristic of each school area. In addition, school landscape should be planned distinction of a elementary school, a middle school, a high school, and a school for handicapped. School landscape should be considered carefully from functional, natural, educational environment and maintenance viewpoints as well as urban forest networking.

  • The fruit color characteristics and persisting period of deciduous woody landscape plants were investigated through the field survey in Suwon region from January 1, 1992 to March 20, 1993. The summary of the study results was as follows; The total fruit color persisting period was about 320 days from May 1, 1992 when Prunus mume was beginning of fruit coloring, to March 20, 1993 when the fruits of Platanus occidentalis and platanus X acerifolia were persisting. And the plants of fruit persisting period over 60 days after leaf falling were Vibumum erosum, Ilex serrata, Ilex verticillata 'Christmas Cheer', Platanus X acerifolia, Platanus occidentalis, Berberis thunbergii 'Atropupurea', Ligustrum obtusifolium. According to the KBS standard color number, 52.6% of of the fruit color were red, 18.9% yellow, 11.6% black, green 9.5%, white 2.1%, violet 1.1%, and red is followed black 4.2%. Evodia daniellii, Ilex verticillata 'Christmas Cheer', Ilex serrata, Ginkgo biloba, Lindera obtusiloba, and Lindera erythrocarpa should be planted male and female species together for fruits. We got the new information on the fruit color characteritics and persisting period of Malus 'Hopa', Malus 'Almey', Malus 'Pioneer X', Acer rubrum, Malus prunifolia, Pyrus serotina, Berberis thunbergii 'Atropurpurea', Vibumum rhytidophyllum, Rosa spp. Vitis vinifera, Vaccinium angustifolium, Ilex verticillata 'Christmas Cheer', Magnolia stellata, Aronia arbutifolia, Sorbus alnifolia, Lonicera japonica var. aueroreticulta, and Ligustrum X vicaryi. And we need to introduce new cultivars of woody landscape plants including Malus spp, Berberis spp, Sorbus alnifolia yellow autumn leaf clone etc. for the better planting design. The fruit persisting period of woody landscape plants studied by fruit name was that sorosis 276 days, samara 155 days, legume 153 days, hip 133 days, pome was 124 days, drupe 92 days, berry 73 days, capsule 67 days, follicle 55 days and nut 52 days respectively.

  • The purpose of this study is to explore the effects of difference in urban tree plantings on microclimate amelioration, and to suggest essential information for quantifying urban energy budgets and energy savings. This study was focused on measuring and analyzing air temperature and relative humidity in summer. Daytime air temperatures at places with 8%, 24%, 44%, 79%, and 100% cover of woody plants were, respectively, $0.6^{\circ}C,\;1.3^{\circ}C,\;2.4^{\circ}C,\;3.5^{\circ}C,\;and\;4.8^{\circ}C$ cooler, compared to a place with 0% cover. A 10% increase of woody plant cover was estimated to reduce the temperature by approximately $0.55^{\circ}C$. The temperature reduction effects were relatively greater between places with lower cover of woody plants than between those with higher cover. Woody plant cover and crown volume were the appropriate indicators which quantified the effects of tree plantings on air temperatures, based on the correlation analysis. Regression equations to estimate temperature change ($Y:^{\circ}C$) using woody plant cover ($X_1:%$) or crown volume ($X_2:m^3$) as independent variables are as follows: $$1nY=3.3233-0.0018X_1\;(r^2=0.99,\;p<0.0001)\;Y=27.5297-0.0019X_2\;(r^2=0.96,\;p=0.0007)$$

  • This study was conducted to find out the fundamentals for proper use of Planting system in the elementary school landscape. For this study, 70 text books were applied to quote the plants, planting situation of 15 elementary schools was surveyed, and 1,464 questionnaires were collected. The resultes and some proposals obtained are summarised as follows ; 1. Total of 177 plant species were quoted over all text books of the elementary school course. Among them, the woody species showed the highest in number with 58 and herbaceous were the next with 30, the other were vegetable of 29, food crops, weeds, industrial ornamentals crops and water plants in order. They were common species in this country and were easy to cultivate except few. 2. 210 species were planted at the 15 elementary schools in Mokpo. It was constituted of 77 of herbaceous species and 133 of woody species but localized Plants were little. The herbaceous plant frequently used were Chrysanthemum morifolium, Targests erecta, Salvia splendens, Petunia hybrida, Cosmos bipinnatus, Celosia cristata, Canna generalis, et. On the other hand in the woody species Juniperus chinensis var. kaizuka, Cerdus deodora, Camellia japonica, and in the shrub Serissa japonica, Thuja orientalis, Euonymus japonica, Buxus mrcrophylla var. koreana etc in order. Almost the same species of woody plants described above were planted in zone of I -IV. Therefore, many problems were found in aspect of aesthetics, and their function and growth. There was much differences in number of species and quantity of plants in each elementary school. However they were not associated with school size, location, and age of schools. Most of elementary schools did not have same the plants as they were represented in text brooks. Therefore, in view of educational purpose it needs to plant more species which quoted in text books.
