This study was conducted to grasp the present condition of the name and the related text of the domestic laws (97 statutes, 1 examination, 1 guide, 3 ordinances, 1 leading case) in force which were connected with landscape plant and planting. Examining the general tree-planting system of America, the related foreign laws(1 constitution, 44 statutes, 31 ordinances, 6 leading cases) were arranged in the name and the text and classified by nations of regional groups and it was considered to the mutual relation with lots of laws which are scattered with the various laws. To examine the points at issue of the related domestic laws and to study the related foreign laws, the remedies for the domestic laws being at issue were proposed. That is : A change of the landscape planting concept, the introduction of the landscape planting cost compared with the total construction cost, the unification of the landscape planting ordinances as the unit of city, the clarification of the completion period for the depect of the replaced trees. putting the conservation and production of the top soil under an obligation the adoption of a licence system for the tree planting within the river area, the introduction of the allotment system for landscape architectural expenses, the encouragement of making a hedge, the settlement for the problems of the trees loss compensation, the necessity for the quality test to the landscape planting works, the intensification of the punitive rules to the illegal felling and planting of the trees in the greenzone area, the application of the Labor Standard Act to the landscape planting laborers. The laws relating to landscape plant and planting are prescribed dispersedly in the many other related laws and it is concluded to be impossible for the legislation of the singular law which is applied uniformly to the department of the tree-planting. Hereafter it should be required to analyze concretely in detail the each text of the related laws by means of the joint studies between the professional landscape architects and the lawyers.

This study analyzes the recognition of commercial business men and employers who operate the commercial zone along the streets in the downtown area on the planting for the roadside green space forming the important frame of greening in the downtown among the open spaces. Through the analysis, this study attempts to get the basic data to suggest the recommendable directions in planting and managing the street trees in the downtown. The results of this study are summarized as described below. The street green spaces are very important in improving the environment of the downtown and their necessities are also very critical. It was found that the street trees were recognized as the critical factor to enhance the aesthetical values of the city, provide the green shades and purify the air. This study also identified that the street trees have the positive impacts on the business environment rather than negative impacts. In maintaining the street green spaces, the most necessity is the service facility such as resting areas, toilets and garbage bins with the street trees. The commercial business men and employers who operate the businesses along the streets preferred the double layer type that the tall trees and green walls are planted together along the streets for the street planting. For securing the green shades in the city, the planting of linear green spaces such as streets and waterways is critical. Moreover, the street trees accounts for the important position in the urban open spaces. The majority of commercial business men and employers consider the participation of citizens for greening as the very essential factor.

Kalopanax septemlobus (Thunb. ex Murray) Koidz. is natively distributed in Korea. The importance of this species has been increased not only for high quality timber but for medicinal and edible uses. However, increasing market demand of K. septemlobus with illegal cutting and overexploitation has resulted in its rapid depletion and destruction of natural habitat. This study was conducted to understand the survival rate and growth characteristics of planted K. septemlobus seedlings with treatment of root pruning, stem cutting and planting density. The survival rate and growth of height and root-collar diameter for one- and two-year old seedlings with different planting densities were investigated in the clear-cut area of a Pinus densiflora stand for five years. One-year-old seedlings were treated with or without root pruning and planted with three density levels (5,000 trees $ha^{-1}$, 10,000 trees $ha^{-1}$, and 40,000 trees $ha^{-1}$). Two-year-old seedlings were treated with and without stem cutting and planted with the density of 5,000 trees $ha^{-1}$. The survival rate of one-year-old seedlings with root pruning treatment in the density of 10,000 trees $ha^{-1}$ was 92%, while that without root pruning in the density of 40,000 trees $ha^{-1}$ was 67% after five years. The height of one-year-old seedlings has been significantly affected only by planting density in the $5^{th}$ year. The survival rate of the two-year-old seedlings with stem cutting was 75.5% and greater than control (67.3%) in the $5^{th}$ year but no difference in height was shown between the two treatments from three years after plantation.

We present a planting plan of the buffer-forest belts created at the boundary area of the waste landfill site which is located in the coastal area of Kyubg-Gi province. In order to form a proper section of ground soil excavated from the sea and a forest which shows a distinction of the vegetation stratification, the planting plan with trees, sub-trees, shrubs, and seedlings (produced at a sprout cultivation place) is devised with an adjustment of planting density. 1. The preparation of mounding is required for planting at a waste landfill site. We first estimate an economical and efficient banking height together with the quantity of soil, and prepare a planting ground with excavated ground soil for the consideration of soil recycling. On the planting ground a banking with a height of 1.5-2m is produced by self-supported soil, playing a role in a salt blocking and an irritation layer of planting. Finally, an additional banking with a height of 2m is produced by qualified vegetation soil, forming a vegetation section with a total height of 6m. 2. Since the planning site is located in the border, the planting area is composed of two regions : one is an inclined face (slope 1 : 3) toward the inside of the landfill site and the other is an inclined face (slope 1 : 4) toward the inland. The buffer planting in the former (latter) region consists of wind break forest (mixed-landscape forest) within a width of less than 35m. 3. Based on the data obtained from the literatures and the investigation of local plants, we choose the 21 plant species (such as Pinus thunbergii, Pinus densiflora, Sorbus alnifolia, Albizzia julibrissin and etc.) and the additinal 7 species which are grown at a sprout cultivation palce of the SUDOKWON landfill site (Rosa rugosa, Quercus acutissima, Prunus armeniaca var. ansu., and etc.). Sub-trees with a height of above 2.5m and seedlings are planted with an interval of $1.5{\times}1.5m$ ($0.45roots/m^2$) and $0.5{\times}0.5m$ ($4roots/m^2$), respectively. Here, both trees exhibit communities planting with more than three rows. Shrubs are planted with $9-16roots/m^2$, depending on their size. Since this case study provides a reference of the planting beds as well as a planting plan at the SUDOKWON landfill site, it is not sufficient for the present plan to be utilized for the formation of buffer-forest belts which are used for the analysis of environmental factor and the reduction of environmental pollutants in the sea waste landfill site. Thus, further studies with the ecological basis are demanded for the environment planting restoration in the sea waste landfill site.

This study surveyed planting areas along streets in Gangwon-do to find out how to improve the planting and use of street trees and herbaceous plants. There were 301,491 trees of 41 species on the streets of Gangwon-do in 2004. The predominant species of street trees were Ginkgo biloba ($40\%$), Prunus spp. (Prunus yedoensis and Prunus sargentii) ($25\%$), Platanus occidentalis ($5\%$), followed by Betula platyphylla var. japonica, Zelkova serrata, Prunus armeniaca var. ansu, Acer palmatum, and Pinus thunbergii. Eighty-four herbaceous plant species were found in the Youngseo district (the southern area of Gangwon-do); the ratio of native species to exotic was 51:33. The predominant species were Cosmos bipinnatus, Petunia hybrida, Tagetes spp., Aster koraiensis, and Fagopyrum esculentum. Eighty-nine herbaceous plant species were found in the Youngdong district (the eastern area of Gangwon-do); the ratio of native species to exotic was 55:33. The predominant herbaceous plants were Aster koraiensis, Tagetes spp., Petunia hybrida, Rudbeckia bicolor, Cosmos bipinnatus, Salvia splendens, Brassica oleraceae var. acephala, Aquilegia buergeriana var. oxysepala, Coreopsis drummondii, Viola tricolor, and Dianthus superbus var. longicalycinus. Appropriate pruning adds to the aesthetic value of trees and prolongs their useful life; it also maintains good health and thereby reduces the need to control insects and diseases. Street trees had not been properly pruned due to the presence of power lines and a shortage of pruning information. The pruning was controlled by Korea Electric Power Company, which has no pruning information. Pruning must be maintained by a professional landscape company in order to maintain good shape, such as that which is done for bonsai. In order to improve the planting, use and maintenance of landscape plants in Gangwon-do, the following recommendations are made: street tree species should be diversified, suitable street trees should be selected for each space, native species should generally be used, trees should be appropriately pruned and properly fertilized, pests and diseases should be controlled, plantings should be done in multiple layers, spatial arrangements should be improved, larger trees should be planted, and drainage and underground electric wires should be considered when planting.

The purpose of this paper is to provide information on planting construction for healthy plant growth. To achieve this purpose, this study analyzed the planting type, planting density, withering rate, soil characteristics, and cambium electrical resistance (CER) of withered trees in an apartment complex with a high withering rate. The major plant groups examined consisted of native broad-leaved tree species (39.3%), native narrow-leaved tree species (24.2%), and native broad-leaved - exotic narrow-leaved tree species (16.4%). The planting density of the green area, where trees were planted from 0.0 to 0.3 trees per unit area, was measured as 98.4%. Withered trees were found in 19 of the 20 planted species, and the withering rate was 41.8% (610 withered/1,461 planted). Withering rates for tree species were measured as follows: Sophora japonica and Salix babylonica (100.0%), Magmolia denudata (84.3%), Lindera obtusiloba (74.7%), cornus kousa (69.3%), acer triflorum (69.2%), diospyros kaki (66.7%), Prunus yedoensis (62.8%), Acer palmatum (52.6%), Prunus armeniaca (51.1%), Chaenomeles sinensis (43.7%), Ginkgo biloba (40.9%), Zelkova serrata (31.0%), Cornus officinalis (28.6%), Taxus cuspidata (25.6%), Pinus densiflora (21.4%), Pinus parviflora (15.2%), Pinus strobus (14.6%), and Abies holophylla (10.3%). Soil chemical analyses for 18 samples revealed that as the withering rate increased, the following occurred: (a) the ratio of silt and clay in soil increased; (b) the soil pH, organic matter rate, nitrogen, available phosphorus, and cation exchange capacity (CEC) in samples were graded as "inadequate," based on the plant grading evaluation; and (c) the NaCl and cation exchange capacity were evaluated as "somewhat satisfactory." The measurement of CER for withering rate shows electrical resistance for higher withering rate are higher, which could predict that a tree will not grow well.

본 연구는 국내 4대강 유역에 조성된 수변녹지를 대상으로 탄소의 저장 및 연간 흡수를 계량화하고, 수변녹지의 탄소저감 효과를 증진하기 위한 조성방안을 모색하였다. 표본 선정한 40개소 연구 대상지의 녹지구조 및 식재기법은 흉고직경이 평균 $6.9{\pm}0.2cm$이고 식재밀도가 $10.4{\pm}0.8$주/$100m^2$로서, 소형 수목의 저밀 단층식재로 대표된다. 식재수목에 의한 단위면적당 탄소의 저장량과 연간 흡수량은 각각 평균 $8.2{\pm}0.5t/ha$, $1.7{\pm}0.1t/ha$/년이고, 식재밀도가 높을수록 증가하는 경향을 보였다. 토양의 유기물함량과 단위면적당 탄소저장량은 각각 $1.4{\pm}0.1%$, $26.4{\pm}1.5t/ha$이었다. 대상지의 수목과 토양은 1ha당 약 61kL의 휘발유 소비에 상당하는 탄소량을 저장하고, 수목은 해마다 1ha당 3kL의 휘발유 소비에 기인한 탄소배출량을 상쇄하는 효과를 나타냈다. 이 탄소저감은 식재 후 5년 이상~10년 미만 생장한 효과로서 식재수목의 생장과 더불어 훨씬 더 증가할 것으로 예측된다. 연구 대상지와 상이한 식재기법의 조성모델들을 선정하여 향후 30년 동안 수목생장에 따른 연간 탄소흡수량의 변화를 비교 시뮬레이션하였다. 그 결과, 경과년도별 누적 탄소흡수량은 식재규격이 더 크고 식재밀도가 더 높은 다층 군식의 생태식재모델에서 저밀 단층식재인 대상지보다 10년 및 30년 경과시 각각 약 1.9배, 1.5배 더 많았다. 수변녹지의 탄소저감 효과를 증진하기 위해서는 규격이 상대적으로 큰 수목을 혼식하는 다층 군식, 속성수를 포함하여 연간 생장률이 양호한 자생수종의 중 고밀 식재, 식재수종의 정상적 생장에 적합한 토양조건 구비 등이 요구된다. 본 연구결과는 조성 초기단계인 수변녹지 사업에서 수질보전 및 생물서식에 부가하여 탄소흡수원의 역할을 제고하기 위한 실용적 지침이 될 것으로 기대한다.

본 연구는 전통공간의 수목정비방안 마련을 위해 광한루원을 사례로 진행되었다. 이를 위해 전통공간의 수종 선정과 수목정비 동향에 대한 이론적 고찰이 선행되었으며, 광한루원의 현장조사를 통한 식재현황을 분석하고, 과거 문헌 및 기록 등에 나타나는 수종 및 식재경관을 토대로 광한루원의 수목정비방안을 도출한 결과는 다음과 같다. 첫째, 전통공간의 수종 선정과 수목정비에 관한 동향을 살펴본 결과, 전통공간 내에 식재된 외래수종에 대하여 맹목적인 지양은 한계가 있으며 전통공간의 수종 선정에 대한 논의는 오늘날까지 이어져오고 있는 시점에서 수목정비에 대한 외래수종의 무분별한 제거 및 향토식물의 맹목적 식재 등의 이분법적 정비방안 및 비검증된 사료의 맹신은 배제되어야 한다. 둘째, 광한루원 내에 식재된 수종을 조사한 결과 소나무, 느티나무, 은행나무, 배롱나무 등 전통공간에서 애용되었던 수종들이 주로 식재되어 있으나 각 공간의 성격을 고려할 때, 광한루 일대를 제외한 광한루원 경내의 수목 식재는 전통공간의 성격과는 무관한 것으로 판단된다. 셋째, 문헌이나 문학작품 등에서 나타나는 광한루원의 수목식재 관련 기록을 살펴본 결과, 현재 광한루원 내에 식재된 수종 중 버드나무류, 배롱나무, 대나무(이대), 연꽃만이 나타나고 있어 고증을 통한 수목정비에는 무리가 따른다. 넷째, 광한루원의 각 권역별 수목정비방안을 모색한 결과, 광한루 권역은 역사적 시대성과 장소성을 지니고 있으며 오늘날 그 모습을 복원해나가고 있어 현재의 상태를 유지하는 방향으로 설정되어야 한다. 완월정 권역은 광한루의 건조물군과 유사한 형태로서 자칫 원형으로 오인될 수 있으므로 완충식재를 통한 전이 공간 조성 등 광한루 권역과는 다른 별도의 장소성 확보가 필요하다. 월매집 권역과 잔디광장 권역은 과거 성외 장시이자 대규모의 숲으로서 율림의 상징적 복원과 동시에 경내의 편의시설 및 관리시설의 집적을 통해 성외 장시의 모습을 재현하도록 하며, 완월정 동측 잔디광장은 완월정 권역과 연계하여 활용적 측면에서 현재와 같이 개방된 형태를 유지하는 방안을 제언하고자 한다. 광한루원 경계 권역은 고증의 측면과 현존요소의 진정성 여부를 살펴보았을 때 전통공간의 장소성과는 연관 짓기 어려운 장소로서 과거 문학작품에서 나타나는 문화경관을 반영하는 것 또한 하나의 정비방안으로 고려할 만하다 판단된다.
