This study aimed to select evergreen broad-leaved trees (EBT) that can be produced and planted in Korea by analyzing the current use of the trees for landscaping in the Kyushu area of Japan, a warm temperate region. The results revealed the total production of EBT was higher than that of conifers and due to the suitable growth environment of the area and the subsequent high demand for them. The landscape tree production methods in Japan were divided into container nursery and outdoor nursery, and the uses and species of the trees varied depending on the method; a variety of native species were produced in container nursery rather than in outdoor nursery, whereas trees used as ornamental, gardening, and shade plants were produced in outdoor nursery rather than in container nursery. The results also showed that in Fukuoka, a major city in Kyushu that is adjacent to Korea, the planting rate of EBT, used as ornamental, gardening, and shade plants, was higher than that of deciduous broad-leaved trees and conifers. In the city, the planting rate of Cinnamomum camphora was the highest, Elaeocarpus sylvestris var. ellipticus, Ternstroemia gymnanthera, Ilex rotunda, Quercus glauca, Camellia sasanqua, Eurya emarginata, Pittosporum tobira, Raphiolepis indica var. umbellata, Hedera rhombea, Kadsura japonica, Trachelospermum asiaticum var. asiaticum. These species were verified in Kyushu area for their application as landscape trees and are expected to serve as landscape trees in Korea if the planting areas of them are expanded by global warming, urban heat island and regional microclimate.

This study is focused on the groping for the alternative ways in order to prevent the various bad factors caused by the Inferior environment on the planted trees. In the reclaimed paddy field which is planned to make a housing site, for example, we are trying to catch the problem about the special feature of the unharmonized drainage. And the survey gives the suitable way of planting trees. This survey was carried out in the three different area and could notice some phenomena : There are a few different conditions for water supply int\ulcorner the soil according to the height of the land-filling from the original ground and the slope of the planting area. And the imporant factor of the drainage effect is not the soil texture itself but the depth of the filling land. As a result of this survey, the study shows the economic alternative for reducing the demage of the planting trees which is due to drainage system.

This study, as a purpose of base study for landscape redevelopement of Seowon, pointed out problems of planting patterns in each sector and suggested an alternative through analyzing old literature, complete enumeration survey in each sector and taking aerial images. the conclusions drawn from this study are as follows. A Pilam Seowon(historic site no 242) is located in a Pyungya-Sanrok(plain and mountain) district in Jangsung-gun and has Junhak-Humyo(Study room in the front and Shirne in the back) type. 23 taxonomic group of arbor, 6 taxonomic group of shrub and 5 taxonomic group of flowers are planted high-densitily in limited flat surface. It can be classified into being planted by family and being planted through landscape redevelopement in 1980s. Korean traditional trees are planted in this area like Pinus densiflora, Juniperus chinensis L., Thuja orientalis L., Zelkova serrato Makino, Sophora japonica L., Lagerstroemia indica, Prunus mume include Ginkgo biloba which is old big tree and is registered in Jangsung-gun as protected trees. The tea tree in this area was introduced from wild tea plantation in Yonhwa moutain and was planted. From now on, we have to pay consideration a form management of planted trees in the historical area, rearrangement of plant density due to over planting, removal of alien trees like Pinus bungeana and Canna generalisa, prevention a dwarfishness of main area due to over planting in outside facilities, recovery a alienation among each planting area, and planting concept from plants drawings on wall of buildings can be suggested. The implications of this case study is that introduction of over planting can make more problems like losing sense of place. Therefore, we must do a actual state survey on traditional landscape area like Seowon from preservation point of view.

The uniformity of lighting distribution on the roadway is essential factor for drivers and pedestrians's safety during nighttime in urban streets. Also, the importance of roadside trees is one of the growing concern for better citizens' health and mitigating environmental impact on the urban street. But roadway lightings and roadside trees have different design or planting standards and they are not integrated in the systemic viewpoint for better safety of users during nighttime. The purpose of this study is to propose a simulation approach which assesses lighting quality in the view of illumination uniformity distribution of roadway lighting from design step and consider the layout of roadside trees. For improving lighting quality of roadway, simulation approach is needed for assessing the impact of diverse planting situation of trees and encouraged from beginning of design step for roadway construction.

This study investigated the status of planting status of school's flower of 11 elementary schools located in Chung-ju and its results were as follows. Totally 3,502 trees were planted in the 11 schools and the number of species of the trees was 103. For tall tree Thuja orientalis was planted most frequently and for shrub Buxus microphylla was done in the largest number of the schools. In addition, the number of trees planted in a school was averagely two times more in the model schools than in the other ones, and the average number of species of trees was also over three times more in the model schools. When the number of species of trees was examined according to their types, decidous broad leaved tree was found most frequently overall and the model schools had more various species of decidous tree compared to the other ones. Investigation on designation of school's flower and tree with the 11 elementary school, revealed similar results with those of previous studies performed with the schools in other areas and the tendency meant that the designation was uniform to some degree. Moreover, as only a few school's flower and tree were planted or no one was done in some schools, the species of school's flower and tree needed to be determined by considering characteristics and school percepts of a school as well as local features and circumstances of a region. In addition, more efforts should be made to infuse love for school and to improve quality of education by increasing the planting rate of school's flower and tree and by focusing them.

The study was designed to learn about features of landscape trees and shrubs on an exclusive area-specific outer space planting plan in Noeun Apartment Complex in Daejeon Metropolitan City. the exclusive areas were no more than $60m^2$ and $85m^2$ and the landscape areas ranged from 15% and 30%, respectively according to exclusive area-to-plottage ratios. The study showed that trees were likely to be more densely planted in exclusive areas not exceeding $60m^2$ than in exclusive areas over $85m^2$. It also found that the greater the exclusive areas were, the larger the number of species became. Regardless of the size of an exclusive use, however, the species number of evergreen trees and shrubs remained small, while there was no remarkable difference in vegetation due largely to a massive influx of special trees or shrubs such as Eastern white pines (Pinus strobus) and Korean azaleas (Rhododendron yedoensis var. poukhanense). The introduction of trees with the height over four meters and the diameter of breast height (DBH) exceeding 15 meters was strictly limited to Japanese red pins (Pinus densiflora) and Japanese zelkovas (Zelkova serrata). In conclusion, it is necessary for us to introduce fresh species of trees and especially develop evergreen trees and shrubs to make the environment of the apartment complex more comfortable and make a vegetation experience feasible.

It is the purpose of this study to arrange in ornamental trees and shrubs the planting that leads to an appropriate type of templescape. The study was designed primarily as an examples for each Buddhist temple which desires further decoration with several ornamental plants, doubles the effectiveness of the Sen-Buddhist meditation, and boosts tourists' attraction. To investigate the planting status and type of trees and shrubs in the precincts of Buddhism temples, We close three temples : They are Nagsansa, Boolgoogsa and Booseugsa, which are intermonatane area temples all together. The results investigated were summarized as follows :1. Planting status and pattern in temples Open spaces of the Daewoogjeon in all temples, a main Sanctuaries in temple buildings, where Buddha is enshrined in, we could not find any kind of trees of shrubs to be planted.Muryangsujeon, a symbol of "Future", which can be also found at Boosugsa temple, is living in Western Elysium world and takes mercy on mankind of this life. Taxus cuspidata was planted at this Muryangsujeon, known as an immeasurable bliss building, where an Amitabha is enshrined in.Total 25 species of trees and shrubs were planted around Birozani building of Buddhist temples, Birozani is enshrined at the Birojion of Boollgoogsa temple.The buddhist Goddess of Mercy which is a buddhist saint for pursuit of fortune and blessing to relieve the mankind is enshrined at Wonchonjeon, Daebijeon and Kwaneumjeon which are able to observe at both Boolgoogsa and Nagsnsa temples, where Euonymus japonicus trees including other 26 species could be found in common at both temples.2. Correlation between trees/shrubs and temple buildingsTrees and flowers symbolizing Buddha are often planted as material sources of gardening to decorate : They are Logerstroemia indica as Buddha's flower, Viburmum opulus var. calvescens resembling Buddha's head, Tilia mandshurica producing the beads of rosary, Gardenia jaminoides Ellis with white flower blade and flower of bliss, not flower to this day and Lotus flowering clearly in the pond filling with dirty water which is able to clarifies the world full of crime, infidelity and injustification. Among these Buddhist' plants, however, Logerstroemia indica could be found in all three temples, and Viburmum opulus var. calvescens at both Nagsansa and Boosugsa. Also, Lager stroemia indica was planted at all three temples and Viburmum opulus var. calvescens at both temples of Nagsansa and Boosugsa. Tilia mandshurica and Gardenia jasminoides Ellis were not found in any temples which might become the subject of investigation.In relation of the buildings of each temples as a sanctified space, the planting of trees and shrubs was not considered for the arrangement, templescape architecture or species. And, also, we could not find in the study any special relationship of trees/ shrubs with the characteristics of temples.With the results obtained through precise studies we presented here in this paper newly designed model of templescape in intermane buddhist temple which can be applied for planting and arrangement of trees or/and shrubs. Basic principles of model in mind are:To consider the correlation of the dominant between plants and temple buildings.To plant trees/shrubs for special functions as well as conditions of temple location.To make tree arrangement correlating to Buddhism spirit.To induce environment friendly plants to be planted, suitable to regional conditions.This redecorated model of templescape might be used as a canon of the tree planting and arrangement in the precincts of Buddhism temples.

The purpose of this study is to develop a model for the density management of planting sites and an additional model for new planting sites. In the Dongtan New Town of Hwaseong, there are buffer green spaces, with widths between 8m and 15m, between roads and apartment complexes. A total 38 survey plots were set to examine the planting patterns and the density of landscape trees. The Crown Overlapping Index (COI) was developed to assess the level of overcrowding as far as tree growth and development effectively. Pinus strobus recorded the most serious level of overcrowding growth and development. Its average density and average COI were very high at $0.3trees/m^2$ and 35.6%, respectively. There were many areas in which its COI was above 45%. The criteria for density management were set by standardizing the COI into three levels, which were above 45% (Type A), 30~45% (Type B), and under 30% (Type C). A model was proposed to manage poorly growing trees and to develop a model to select and manage trees of similar specification based on the planting patterns. The trees of density management areas were reviewed in terms of tree types and the ease of transplanting to establish an application system for the management plans according to the possibility of transplanting, thinning, and pruning. In new buffer green spaces, the planting density of Pinus strobus was lowered to $0.20{\sim}0.25trees/m^2$, with that of shrubs being reduced to $1.5{\sim}2.0trees/m^2$, leading to a planting design model to cover the lower parts in at least 30~40%.

The purpose of this study is to establish the strategic direction of school forest based on the analysis of planting species and status and environmental consciousness of students on 9 elementary schools in Gyeongsangbuk-Do. According to the results of analysis of planting status, the green space area of Ahwa elementary school was increased as $2,300m^2$ and the green space area of most schools was increased more than $500m^2$ by the construction of school forest. The planting species were surveyed as 109 species in total and the deciduous broad-leaf trees and herbaceous plants were identified by each 29 species. As a result of analysis of elementary school students' awareness on school forest using surveys, the ratio of students that know school forests is 58.9% and the ratio of participation is 20.7%, that is very low. Finally, in the direction for the desirable construction of school forest, the students evaluated by preferring the evergreen broad-leaved trees, flowering trees and fruit trees and they required the development of teaching materials and program and the quantitative increase of forest.

The purpose of this study is to analyze historical records of what the trees had been planted like by establishment and management of the Royal Tombs of the Joseon Dynasty so that it could be utilized for historical records to manage the trees in the Royal Tombs. The research method was to analyze the related keywords for 40 trees out of 42 trees in the Royal Tombs of the Joseon Dynasty reffering to "The Annals of the Joseon Dynasty(朝鮮王朝實錄)," and "Neungji(陵誌)". There are two types of planting called Jeongsik(定植) Bosik(補植) in the Royal Tombs. Jeongsik(定植) is a planting method by Salleungdogam(山陵都監), the office in charge of construction of the royal tomb when they were building the royal tomb. Every tree additionally planted after building up the royal tomb was called Bosik(補植). The types of tree planting the composition and management of the royal tombs of Joseon are as follows. First, the first planting for landscaping was carried out during the process of building the province. Second, after the formation of Shanung, all the plants were planted by Wangmyung as additional plants. Third, due to the deforestation in the late Joseon period, additional plants were planted in the fertile plains. Fourth, trees were damaged due to natural disasters, and trees were planted together with the construction of the botanical gardens. Fifth, in the 22nd year of King Jeongjo, all the royal families' graves were regularly planted. This study aims to investigate the history of forest landscape management for the restoration of the royal tombs of Joseon.
