The purpose of this study is to create a database of the use of landscape greenery that surrounds commercial buildings in Seoul. The method of this study was: to review preceding studies and related laws, survey areas, measure trees, and analyze the results. The 20 representative sites were specifically investigated to measure the width, direction, and environment of planting conditions. To analyze the greens adjacent to the building, the greens were divided into three types: front greenery, side greenery, and rear greenery. The study surveyed the distance from trees to adjacent buildings, and their planting conditions. The results of this study are as follows. First, 45% of the front greenery and 30% of the rear greenery were not established, but 19 of the 20 side greens were. Second, 13 of the 44 green areas adjacent to commercial buildings were under 1m in width. Most side greenery was belt -shape and unrelated to the features of the site or building. Third, the average distance from trees to buildings was 0.76m, indicating that most trees were planted too close to the buildings. Fourth, of the 30 trees utilized, the species breakdown was: 8 evergreen trees, 15 deciduous trees, and 7 shrubs. For the most part, planting patterns were similar for all species. Fifth, most sites were ill-suited to tree growth, because crown shape, planting conditions, and light conditions, etc., had not been considered. Based on these results, it is suggested that more specific, subdivided standards for planting conditions should be established. For example, building plans should include a green area that is at least one meter in width. In addition, according to the location and type(closing/opening) of the greenery adjacent to the buildings, suitable management programs and supervision protocol should be adopted.

In this study, the analysis carried out on characteristic of planting species and planting density of parks and green spaces in downtown city of Haengjeong-dong in Wonju, Gangwon Province. We found that 8,050 coniferous trees (19 species), 6,037 deciduous trees (61 species) and 77,609 shrubs 103 species were planted in the parks and green space in Haengjeong-dong. However, a conifer Pinus strobus is highly concentrated in all four kinds of places which are neighborhood park, children's park, green buffer zone and landscape green space regardless of their period of construction and usage of surrounding land and other trees were planted in order of Pinus koraiensis, Prunus yedoensis, Acer palmatum, Zelkova serrata, Pinus densiflora. Average planting density of parks and green spaces is $0.03tree/m^2$ for a tall tree and $0.18tree/m^2$ for a shrub, which shows low planting density in most parks and green spaces of Wonju. Also, understory vegetation was not planted enough. Since area of lawn is wide in green spaces, planting density is needed to be increased and tall trees should be planted more. Therefore, we suggest planting more trees in an area where trees are not planted, multi-layered vegetation and increasing in planting density through shrub planting etc., by identifying spaces for trees to be planted within parks and green spaces.

This study was conducted to obtain information relevant to resolving problems related to artificially introduced plants in ecological restoration projects. We investigated artificially introduced plants and plants growing naturally from its surroundings in the active restoration sites of the Ecosystem Conservation Fund Return Project (ECFRP) of the Ministry of Environment and the Civilian Control Zone Forest Restoration Project (CCZFRP) of the Korea Forest Service. We also analyzed the characteristics of native, exotic, and cultivated plants in addition to their Raunkiaer's life forms. Furthermore, we compared the planted areas and inhabited areas, as well as the characteristics of the habitats of native plants among the planted plants. We found that among the plants planted in the ECFRP, 50.4% were native, 6.8% were exotic, and 42.9% were cultivated. Meanwhile, in the CCZFRP, 78.6% were native, 21.4% were exotic. We also noted that many native plants were found in the planted areas that were far from their habitats. In addition, we identified many native plants that were planted in areas judged to have characteristics different from that of their natural habitat. In the case of Raunkiaer's life forms, the planted plants showed high ratios of megaphanerophytes (MM) and microphanerophytes (N), while the invasive plants showed high ratios of therophytes (Th) and hemicryptophytes (H). When restoring the ecosystem, the ratio of planting native plants should be higher than that of exotic or cultivated plants. Moreover, the habitats and ecological characteristics should be considered when selecting native plants to enhance the effect of ecological restoration.

To seek for restoration method of Abies koreana forest with planting seedlings, Abies koreana seedlings(2, 3 and 5 year old) were planted by date(spring and summer) and surface treatment (coir-mat, coir-net and control) at Janggumok area in Hallasan. Survival rate and shoot growth of the seedlings were measured and compared by planting date, seedling age and surface treatments. For summer planting, survival rates of the seedlings are increased with increasing seedling ages, and those are not differed between surface treatments. For spring planting, survival rates of the seedlings are increased with decreasing seedling ages, and those are not differed between surface treatments. For summer planting, shoot growth of the seedlings are significantly differed between surface treatments. Shoot growth of the seedlings was the highest value 2.11mm at coir-matted plot, and the lowest value 1.49mm at control B)lot. Shoot growth of the seedlings are not differed between the seedling ages, but the highest shoot growth was 2.26mm at coir-matted and 3-year old plot. For spring planting, survival rates and shoot growth of the seedlings are not differed between seedling ages and surface treatments.

This study aims to present an evaluation scheme to improve the problems in tree shapes and tree growth which were identified through shape and growth assessments of landscape trees currently planted in Haedoji Park, Songdo, Incheon Metropolitan City after plant structure status and propriety review for funtion of space and concept of planting. Suitability the planting concept was evaluated according to function of space. The result indicated that the shade planting areas accounted for 29.5% of the the shade spaces area. 58.7%, respectively planting areas of visual landscape. And 11.8%, respectively planting areas of buffer. Because the planting areas was lacked according to the park established spatial configuration of central facilities and the result of plant young trees. Plant structure status required consideration with plant structure, density, size, growth status for improve planting function. The tree assessment was performed on a total of 28 species and 600 trees of which 22 species and 209 trees were planted in the buffer zone, 8 species and 71 trees in the shade zone, 16 species and 266 trees in the visual landscape zone, and 4 species and 54 trees in the ecological landscape zone. The trees were divided into grades based on their assessment score and were statistically grouped by the functional zone in where they are planted and by tree species to verify their significance. The tree shape assessment was an average of 56.6 points and the tree growth assessment was an average of 76.0 points. Using the results of the tree assessments, the tree standards for each functional space were identified and a concept of optimum planting and cultivating was applied. When applying the shape assessment results by zone to the concept of planting, since trees for buffering require high functionality they received E's, the lowest grade; as trees for ecological landscaping require diverseness and naturalness, they received D's; since trees for shading require utilization, they received C's as trees with branching at the main stems were considered; and since trees for visual landscaping required aesthetical value, they received A's and B's. When applying the growth assessment results by zone to the concept of planting, based on planting foundations of favorable and poor, for buffering, visual landscaping, and ecological landscaping, trees from grades A to E could be planted, and for shading, trees from grades A to C could be planted. For a cultivation plan that could improve the growth of the trees, we proposed that the topography of the land be selected considering the tree's characteristics and that a method of pot seeding be used. Also, to improve the shape of the trees, we proposed that poles be used to improve the growth of vertically-straight stems, an appropriate planting density be applied for reasonable branch growth, manage tree shape to maintain good crowning, and better manage fertilization to maintain a reasonable crown density.

This paper categorized the functions of and investigated the characteristics of planting in Pyeonghwa Park near the Seoul World Cup Stadium as a preliminary study for improving tree planting in the park. The functions of planting were deduced based on related theoretical studies and an analysis of the intention of design and environmental factors. The characteristics of planting were analyzed after drawing the distribution and stratification of dominant planting species and setting samples by function. The functions of planting were classified into natural landscape planting, buffer planting, and shade planting. For dominant planting species, pine trees and elm-like trees have been widely observed while various species in addition to pine trees in natural landscape planting areas have been introduced in terms of the function of planting. These trees that were randomly planted before the park was developed have been obstacles in the formation of natural landscapes. For buffer planting and topographical correction, tall trees were planted. However, it seems that comprehensive complementary measures should be taken on the under-story planting.

Bunhwangsa Temple, Baekryulsa Temple and Sambulsa Temple are not famous cultural heritage area, but they are visited by many tourists and are located in Gyeongju National Park and Gyeongju Historic Areas, so environmental and cultural preservations are required. The purpose of this study is to manage the unique environment and landscape of cultural assets by analysing the invasive alien plant of traditional temple of Gyeongju. The whole flora were summarized as 188 taxa including 73 families, 136 genera, 154 species, 3 subspecies, 11 varieties, 4 forms, 5 hybrids and 12 cultivars., and the landscape plants were 163 taxa and 38 taxa of the invasive alien plants. The 13 taxa of invasive alien plants were planted in three temples. The ecosystem disturbance species were 3 taxa including Rumex acetosella, Lactuca seriola and Symphyotrichum pilosum. Invasive alien plants have artificial causes such as landscape planting, but there are also those that are introduced naturally from outside. The parking lot of the temple is expected to be a major propagation path for invasive alien plants due to the large amount of interference and disturbance. Based on the results of this study, the management plans are suggested as follows. First, it is necessary to use native species suitable for the natural environment and traditional landscape of Korea for landscape planting of traditional temples, and development of planting guidelines centered on cultural properties is required. Second, it is necessary to refrain from planting invasive alien plants because traditional temples are located in an important environment and historically. Third, for the preservation of the temple environment, it is necessary to promptly remove the ecosystem disturbance species. Fourth, in order to express the landscape characteristics of traditional temples, a unique planting plan should be established in consideration of the location environment and historicity.
