대규모 개발사업을 시행함에 있어 우리는 종종 무의식적으로 토양층을 교란시키게 된다. 식물 성장에 있어 토양은 영양분을 공급하는 중요한 역할을 하고 특히 토양 중 표토층은 식물 생장에 필요한 많은 영양성분을 갖고 있으므로 토양층의 파괴는 식재된 수목의 하자와 직접 연결된다. 살아있는 식물을 다루는 조경공사에서는 공사 후 높은 하자율을 걱정하기에 앞서 수목의 원활한 활착을 위해 토양을 건강하게 유지하도록 노력해야 한다. 본 연구에서는 수목과 토양의 생리학적 관계 및 토양의 기본적인 성질과 표토의 중요성, 표토의 특성을 유지하는 방안 등에 대해 고찰하고 사례연구로 한국토지공사에서 시행한 용인 동백지구의 표토 활용사례를 검토하여 문제점을 파악하고 보다 효과적인 표토층 보존을 위한 방향을 제시하고자 한다. 수목의 성장률, 건강도, 수형 등은 직접적으로 토양의 질과 연결되고 양질의 토양은 수목의 원활한 생장을 가져와 결국 수준 높은 경관을 형성할 수 있게 된다. 본 연구를 통해 수목과 토양의 생리학적 관계를 파악하고 수목의 성장에 적정한 환경을 제공함으로써 불량한 토양으로 인한 수목의 하자율을 사전에 방지하고 수목의 건강성을 유지하는 방안 설정에 도움이 되고자 한다.

The purpose of this study was to analyze judicial precedents related on landscape construction defects(JPLCD) and suggested the improvement plan for dealing with it. The results are as the following: 1. Landscape construction defects litigations have been increased so far since 2000 and the duration of original trial was approximately 603 days, while appeal trials took up to 550 days. Therefore, the analysis revealed that settlement of disputes were lengthy and wasteful to consumers and constructors. 2. Judgement's cost accepted by the judge was only 53.6% of appraisal's cost appraised by appraiser, therefore it revealed appraiser overestimated the repair cost of landscape construction defects. 3. According to work classification categorized by Landscape Construction Standard Specification(2008) of the Korean Institute of Landscape Architecture, landscape planting amounted to 75% of JPLCD and plaintiff(consumers)'s prevailing rate of it reached 77% to be a serious burden to constructors. 4. According to JPLCD categorized by the type of dispute, defects caused by consumer's negligence for maintenance amounted to 29% and defendant(constructors)'s prevailing rate of it reached 64% to be the main responsibility of consumers. Further study will be required to make the judge standard of landscape construction defects through legal and technical research.

The government is promoting the reorganization of the construction indusrty under the theme of reorganizing the production system. However, it has been pointed out that this is contrary to the increasingly specialized and technical skills of the landscaping field. Therefore, it is urgent to respond to the construction industry integration policy and improve an appropriate work system and the content of the landscape field. Therefore, this study investigated the intention of the industry to reorganize the production system and the production structure of the landscape field, so that it can be used as a reference for future changes. As a result of the survey, 1) the perception of the reorganization policy is a highly requesting step-by-step promotion that reflects the industry's will, 2) the system is divided into generalization and specialization and is highly opposed to integration, 3) appropriate design and construction costs are the most important directions for improving landscape construction projects, and 4) reestablishing the relationship with related civil engineering works is important for improving detailed construction types. Overall, it was pointed out that the current specialized landscape construction does not sufficiently reflect the changing landscape business and is only appropriate for subcontractors in other industries. Therefore, it is necessary to promote policies that reflect this. In the long run, it is urgent to establish the status of landscape construction as an independent object, and it is necessary to supplement the legal system and change the industry accordingly.

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.

This study was conducted to investigate the planting status of the woody landscape plant species and to obtain some fundamental informations for improvement of production and sales circulation of the woody landscape plants. The details of 328 landscape projects which were carried out for 2 years from 1983 to 1984 were surveyed to investigate the utilization status of the woody landscpe plants. The results obtained are summarized as fellows ; 1) The utilization rate of the trees to the shrubs as woody landscape plants was 1 : 6 and that of the evergreens to deciduous plants was 1 : 4. The plant species which were most frequently used in landscaping were Buxus microphylla koreana, Juniperus chinensis, Zelkova serrata and Acer saccharinum, howevr, plants which were used in largest quantitites were Ligustrum obtusifolium, Forsythia koreana, Buxus microphylla koreans and Rhododendron yedoense var. poukhanense. 2) The number of plants planted among 3 shrub species(Ligustrum obtusifolium, Forsythia koreana and Buxus microphylla korana) exceeded half of the total number of shrubs planted for landscping, however, the number of plants planted among 8 tree species including Pinus koreainensis were about half of the total tree species. 3) The number of government price specified plant species was only 20%, but the utilization frequency of the price specified plants was as much as 6 times than unspecified plants and 85% of plants used in landscaping works were the price specified plants. The utilization rate of the price specified plants was significantly high in the shrubs than the trees and in the evergreen than deciduous plants. 4) The amounts in use of the price specified standardized plants were significantly more than those of unstandardized plants. When the plant heights are same, the plants having wider canopy or stem diameter were rather frequently used in the landscaping works. The ratio of the width of the canopy or stem diameter to the stem length of the plants in the Korean standard is significantly greater than that in the Japanese standard.

In this article, I would like to analyze the conditions in applying the LCC method for each construction type by selecting 10 apartment complexes among the Turn-key projects which have been ongoing for the last 5 years. In addition, this article will identify the problems to the application of double landscape architecture and suggest improvement measures. Among the 10 case targets, a total of 151 LCC analyses were conducted, and the average application ratio placing for each construction type was shown in the following order: architecture (34.4%)> electricity (21.2%)>machine (18.5%)>civil engineering (13.2%)>landscape architecture (12.6%). As numbers show, landscape architecture was the lowest. The ratio of LCC reduction amount was shown in the following order: machine (32.1%)> architecture (23.9%)>electricity (23.4%)>civil engineering (17.5%)>landscape architecture (3.1%). The field of landscape architecture had a reduction amount that was about 5 to 6 times lower than civil engineering which had a similar number of LCC analysis cases. The total LCC analysis items of landscape architecture was 19, including 15 double packing material, 1 building covering, 1 grass planting, 1 planting infrastructure, and 1 facility. The following measures were suggested to promote LCC analysis in landscape architecture: first, set an analysis item that considers the construction expense ratio of landscape architecture; second, legal regulation of landscape architecture and expansion of its application; third, prepare VE/LCC standards which are suitable for landscape architecture.

This study started with the question, "Is the cost of landscape construction work in residential areas measured by public enterprises, 'in response to the needs of consumers?" The study analyzed whether the landscape construction expenditure is being introduced at an appropriate ratio according to the value the residents have regarding landscape elements. Following this, research was conducted for the purpose of providing basic data for improving the efficiency of formulating apartment landscape construction costs in the future. This research proceeded based on a questionnaire survey of residents of apartments, and the content of the questionnaire used frequency analysis and descriptive statistics research methods. To take a look at a comparative analysis of value recognition, in particular, a comparative analysis was performed based on the actual input cost based on the ratio of landscape elements by layer. Conclusions were found as follows: First, the degree of interest in the apartment landscape of the tenants was high, and the value of the landscape was high but realistic satisfaction appeared comparatively low. Second, the awareness of residents' values regarding landscape elements appeared to give "plantings" more value than "facilities". Thirdly, as a result of a mutual comparison between the values recognized by the resident regarding landscape elements and the construction input fee, depending on the landscape elements, it appeared that there is a difference in the ratio of up to 52 times from 1.25. Fourth, the fact that there is a difference in the relative proportion of value recognition and inputting construction cost indicates that it is not possible to respond to the needs of tenants during the construction cost development process. It also shows that the utility of inputting construction costs is low. Therefore, a macro-level examination such as reflecting the existing inflation rate is necessary to develop the efficient landscape construction cost of apartment such as the awareness of the value of the residents regarding landscape elements, out of the customary construction cost formulation method based on the microscopic dimensions of the consumer side.

The purpose of this study is to examine the design ＆ construction methods of the traditional landscape space of the past and the repair and maintenance of cultural heritages to maintain it today. To this end, the method of narrative description, process extraction and construction related to traditional landscaping were compared to each other based on the 『Imwongyeongjeji』 「Seomyongji」 and 'Standard Specification for Repairing Cultural Heritages'. The results are as follows; First, to analyze at the description methods of the 『Imwongyeongjeji』 「Seomyongji」 and 'Standard Specification for Repairing Cultural Heritages' and related processes in the field of traditional landscaping. 『Imwongyeongjeji』 「Seomyongji」 was an encyclopedia of the overall construction method of the living space, describing the location, effect, and advantages and disadvantages of each component and presenting quantitative figures to institutionalize the construction of traditional landscaping spaces. 'Standard Specification for Repairing Cultural Heritages' presented the entire process of repairing cultural heritages, and it is becoming a kind of guide for reference at the site. Among them, foundation construction, roof construction, landscape construction, and fence construction were drawn as items that could be applied to traditional landscaping areas. Second, the traditional landscape space construction method was divided into the processes of foundation construction, roof construction, landscaping construction, and fence construction. Foundation construction is a way of repeating the process of land-tramping. During the construction of the roof, the tile-roofed building was built on top of the rafters and roofed with tiles. And thatched roof was made to a number of rice straws bundles to cover the roof one after the other. Instead of tiles, the stone roof was made of thin and wide stones, and the wooden boards were used for the single roof and the bark roof were constructed with many layers of dried corrugations. Landscape construction mainly consists of the Paving technique through tramping rubble and the construction of terraced flower by planting stone, plants, and shrubs on the top. According to the building materials, the wall construction was derived from the earth-stacked earthen wall, stone walls using stone and clay, marble walls made of tile patterns, and the construction of a board wall using a wood board as a wall. Third, comparing the construction methods of the 『Imwongyeongjeji』 「Seomyongji」 and 'Standard Specification for Repairing Cultural Heritages', 『Imwongyeongjeji』 「Seomyongji」 focuses on standardizing the construction methods to create a new traditional space. There is a difference in the setting of the scope of the 『Imwongyeongjeji』 「Seomyongji」 and the construction because 'Standard Specification for Repairing Cultural Heritages' provides the overall construction procedure considering the diversity of the cultural heritages. In addition, the traditional landscape space used to be a residential space in the past, but today, the maintenance process of the already established facilities as designated cultural heritages has been carried out, and construction methods have been added to create viewing conditions. In terms of the succession of traditional knowledge, some similar methods were found in the repair of cultural assets today, and some cases were also confirmed in the reconstruction of traditional technologies such as application of some materials or mix, separation of added facilities and introduction of efficient construction methods.

Most landscape areas in apartment complex have been changing. Increasing the area of underground parking lots have an effect on apartment's circumstance. Natural ground was decreased so that the most space in apartment complex were converted into an artificial ground. To suggest the soil quality management, this study examined the actual situation about the soil quality of planting ground such as the quality standard as artificial soil, the difference of natural ground, and the difference of soil quality according to the work classification. As a result, the soil quality of the apartment complex with a large underground parking lot had low quality of soil. Soil physical properties were relatively fine but soil chemical properties needed the quality control. The soil quality of natural ground and artificial ground was not statistically significant and the soil quality by the work classification also had no statistical significance. Therefore, we established improvements about standards of the chemical properties for quality management, the soil quality in the natural ground and applying the equivalent standard according to the work classification.
