This study was carried out to propose improvement planting method by the research and analysis of planting concept, planting density, planting style and pattern in apartment complex, Seoul. Survey sites were selected by reflecting the change of green area ratio : Hawgok Jugong apartment complex, Gangseo-gu(1974), Samik-green apartment complex, Gangdong-gu(1980), Dongsindaea apartment complex, Gangseo-gu(1992). Green area in apartment complex was classified with front green area, side green area, and back-side green area. Planting concept that composed of landscape planting concept but anyother concept was not, was similar to all sites not differ from creation time. And planted species was not differ from planting style. Planting density was of both conopyㆍunder story layer was 0.0∼0.2 tree/$m^2$, and that of shrub layer was 0.0∼0.5 tree/$m^2$ Shrub layer planting density was insufficient and the density was not changed according to the creation time. Canopyㆍunderstory and shrub was planted to another green space, not concern with multi-layer structure. Planting pattern was utilized to single planting, linear planting, and random triangle planting, but it was not to the change that in each green space planting concept. Green area in apartment complex should be variety according to planting density, planting structure and planting pattern. And we should get the function of covering and beauty in case of front green space, that of ecological environment and increasing green volume in case of back-side green area, that of increasing green volume in case of side green area, apartment complex.

This is an empirical study to investigate the types of plants used in Gertrude Jekyll's wild gardens, identify relationships between plants, and analyze the planting patterns. Four sites were chosen for the study: the Cotswold Cottage, the Dryton Wood, the Little Aston, and the Frant Court. To find direct relationships between plants from the planting patterns shown in these gardens, the social network analysis program R was used to analyze degree centrality, which resulted in the identification of top three plants, followed by looking into their characteristics and meanings. The summary of the results is: Azaleas(Rhododendron spp.) showed the highest degree centrality, followed by wild roses (Rosa spp.). Cold-resistant crossbreed azaleas were used as underplanting connected to many different plants, creating the feeling of an atypical woodland garden. As an indigene, wild roses showed high degree centrality in terms of ecology and aesthetics, forming multiple layer planting. Also, plants with small white flowers, for example rowans(Sorbus commixta), shadbush(Amelanchier asiatica), sealwort(Polygonatum odoratum), and American columbines(Aquilegia vulgaris) were planted in these wild gardens as plant colonies to make natural connections with other plants through drifts.

수목이 존재하지 않는 하천과 비교하여 하천 내에 수목이 존재하는 경우, 수목에 의한 항력에 의하여 수위는 상승하지만 차이는 크지 않으며, 수목이 식재된 구간의 유속이 현저하게 저하되는 것으로 알려져 있다. 식재구간과 비식재구간의 현저한 유속차이는 활발한 에너지 교환에 기인한다. 이러한 특성은 하천에 여러 가지 시설물 설치 및 수목 식재 계획 수립 등에 있어 고려되어야 할 사항이다. 또한 수치해석을 통한 정확한 흐름예측을 위해서는 두 구간 사이의 합리적인 에너지 교환계수를 결정하여야 한다. 수목 식재구간과 비식재구간의 에너지교환 특성에 대한 연구는 대부분 모형식생(단순한 봉 형태 위주)을 이용한 소규모 개수로 실험장치를 이용하거나, 이론적으로 접근하고 있다. 이러한 연구는 흐름 상사 등을 고려할 때, 정성적인 분석에 그치고 있으며, 정량적인 분석을 위해서는 원형에 가까운 실험시설을 이용하는 것이 타당할 것으로 생각된다. 본 연구에서는 단면의 높이, 상단폭, 저면폭이 각각 2 m, 11 m, 3 m인 소하천에 가까운 실험수로에 관목류(왕버들)를 식재하여 실험을 수행하였다. 수로의 중앙부와 사면에 식재된 경우, 식재 패턴이 다른 경우(parallel space, staggered space) 등 다양한 조건에 대하여 흐름특성을 분석하였다. 각 경우에 대하여 배수곡선을 측정하여 흐름저항 특성을 분석하였으며, 50Hz의 자료 획득이 가능한 micro-ADV를 이용하여 횡단면의 난류량을 측정하였다. 측정된 난류량을 이용하여 전단속도의 변화, 난류에너지 변화 등을 분석하였다. 이 연구는 하천내 수목식재 계획 수립, 수치모형의 중요한 매개변수인 에너지교환계수의 합리적 결정에 기여할 수 있을 것으로 보인다.

This study focuses on the reconstruction of buffer greens which were installed to reduce environmental effects on roadsides constructed in the 1980s, in order to supplement various urban green functions. The subjects were buffer greens installed along the Songpadaero and Nambusunwhanro in Songpa-gu. Planting was suggesting to strengthen the buffer, landscape, shading and ecological function according to the use of the buffer green surroundings. The surroundings of the green axis subjects are high-rise apartment areas, neighboring commercial areas, commercial working areas, transportation facility areas, urban support facility areas, schools, parks, etc. However, the structure of the buffer greens were uniformed with Plantanus occidentalis and Ginkgo biloba and Zelkova serrata in the canopy layer and with Forsythia koreana and Ligustrum obtusifoliumin the shrub layer in lineal or alternate order, functioning only as buffer space. Therefore, the buffer greens need to be reconstructed， supplementing various functions according to land use, in order to improve the pedestrian walk area in terms of landscape and use of greens. In line with that, the planting improvement plans according to the land use patterns, and physical and ecological structure were classified into buffer and landscape, landscape and buffer, buffer and shading, and buffer and ecological function. In addition, improving planting function, species and facilities are suggested.

하천 내 식생에 의한 유속차이는 활발한 에너지 교환에 기인하며 하천 내 흐름 변화에 큰 변화를 가져온다. 또한 식생에 의한 하천 침식과 퇴적의 반복은 하천 지형 변화의 대표적인 원인 중 하나이다. 따라서 본 연구에서는 소하천을 대상으로 관목류(버드나무류)를 식재하여 식생유무 및 밀도 차이에 대한 흐름패턴 및 유속 변화를 분석하였다. 식생은 고밀도(식생 수 : $38/m^2$)와 저밀도(식생 수 : $10/m^2$)로 구분하였으며 유속 측정은 ADCP와 micro-ADV를 이용하여 비교하였다. 실험 유량은 식생 침수 정도에 따라 부분침수($0.5m^3/s$), 완전침수($3.7m^3/s$)로 나누어 실험을 수행하였다. 실험결과 ADCP와 ADV에 의한 유속값은 유사하게 나타났으며 고밀도일수록 식생에 의한 항력으로 인해 느린 흐름을 보였다. 또한 부분침수 시 식생 내 수심 증가로 인한 흐름 변화가 발생하였으며 완전침수 시에도 식생 유무 및 밀도에 따라 흐름 패턴이 바뀌는 것으로 나타났다. 향후 이 연구는 하천 침식 등을 고려한 수목식재 계획 수립에 기초자료로 사용될 수 있으며 다양한 식생을 대상으로 조도계수 변화, 흐름특성 분석 등이 추가적으로 연구되어야 할 것으로 판단된다.

The purpose of this study was to find a basic theory about Korean traditional planting pattern by analyzing a characteristic of planting and planted species in Haein, Tongdo and Songkwang Temples. The results are as follows. The planted species in three-treasure temples were 129 taxa; 57 families, 96 genera, 110 species, 12 varieties and 7 forma. The species related in Buddhism were Viburnum sargentii for. sterile, Hydrangea macrophylla for. otaksa and Musa basjoo. They are related in plant form and Buddhist ceremony. The results of forms were 34.1% in trees, 33.3% in shrubs, 3.9% in vine and 28.7% in herbage. The results of leaf fall were 56 taxa in broad-leaved deciduous trees, 27 taxa in broad-leaved evergreen trees and 14 taxa in needle-leaved evergreen trees. The native species were 32 taxa in Haein Temple, 27 taxa in Tongdo Temple and 44 taxa in Songkwang Temple. And the exotic species were 20 taxa, 28 taxa and 44 taxain the Haein, Tongdo and Songkwang Temples, respectively. In the results of analyzing the characteristics of planting, in the case of Haein Temple, Abies holophylla was linearly planted in Yiljumun, and Magnolia denudata was single planted in plant stairs of Haetalmun. In the case of plant stairs of Jeokmukdang, Cephalotaxus koreana was planted at regular intervals. In the case of Tongdo Temple, Celtis sinensis, Zelkova serrata and so forth were planted in Yiljumun, and Phyllostachys nigra was planted in form of screen planting in Youngsanjeon. The form of Hwanghwagak was a planting of symmetry in the center of a building, and the one of Daekwangmyyeongjeon was a mixed planting. The regular planting pattern was not shown in Yiljumun of Songkwang Temple. In the case of Dosungdang, Corunus officinalis was linearly planted in the west. In the case of Gwaneumjeon, Juniperus chinensis var. globosa and Camellia japonica were planted in symmetry. The old aged trees were planted in front of specimens planted in front of Daewoongbojeon.

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.
