Due to the increase of carbon dioxide in the atmosphere and global warming, the importance of forest ecosystems, as a place of carbon accumulation and emission, has received a great amount of recognition lately. This study was performed to help understand and provide the current status of carbon cycle in the pinus densiflora stand, Korea. The samples were collected from average 35-years-old Pinus densifiora rands in Gongju, Youngdong, Chungsan, Muju, Mupung, and Jangsu regions. Total thirty aboveground sample trees were cut, and ten roots were sampled, and soil samples were collected. Average carbon concentrations in foliage, branch, stem bark, stem wood, and root were 55.7%, 56.0%, 56.0%, 57.3%, and 56.5%, respectively. Carbon content was estimated by the model
where Wt is oven-dry weight in kg and D is DBH in cm. Total carbon content (aboveground and root) was 42.39tonC/ha in the Pinus densiflora stand. The proportion of each tree component to total carbon content was high in order of stemwood, root, branch, stem bark, and foliage. Total net primary production (aboveground and root) was estimated at 6.51tonC/ha/yr in Pinus densiflora stand. The proportion of each tree component to total net primary carbon content was high in order of sternwood, root, branch, foliage and stembark. Soil carbon contents in the study sites was 43.51tonC/ha at 0-50cm soil depth.

Journal of the Korea Society of Environmental Restoration Technology, volume 12, issue 2, 2009, Pages 10~18
In order to determine the violation of right of light impact at adjacent residential area by high-rise building, analysis on the right of light for high-rise residential commercial complex building block at Gahngnam-ku, Seoul, Korea was carried out using Google Sketchup Pro. After the analysis th sunshine duration of B apartment decreased from 5 hours 16 minutes 3 hours 48 minutes by I hour 42 minutes after construction. It shows that the total sunshine duration is less than the Seoul City Government Standard which is more than 4 hours a day, or more than 2 consecutive hours. Lowering the heights of apartments by 54m would increase the total sunshine duration which would meet the Seoul City Government Standard by four hours seven minutes. Problems that rna lead to the violation on the right of light in the adjacent area should be discussed in advance and minimized by analyzing the right of light among buildings and structures which are scheduled to be constructed on the site during construction penni! process when high-rise building is proposed.

Echinosophora koreensis (Nakai) Nakai (Leguminosae) is one of the threatened plant growing in secondary forest with sparse pine forest. The aim of this research is to investigate current status in a habitat of E. koreensis population, and obtain knowledge for conservation of the population. The flora of vascular plants and vegetation were investigated in the habitat E. koreensis in Mt. Bibong, Gangweon Province. Investigation were carried out in August 2003 and May 2008 at the three different habitats. As a result, a total 40 species 7 varieties of 28 family were recorded in whole area. The vegetation of investigated area was typical northern-temperate Pinus forest, humidity of soil was low and located at a slope area. These investigated area is very important for conservation of rare plant, E. koreensis. Therefore, sustainable conservation strategy such as designation of conservation area should be prepared urgently by the results of long-term monitoring studies.

Research was initiated to investigate a vegetation characteristics of the winter season by seeding periods. 3 seeding periods (Mid-December seeding plot, Late January seeding plot and Early March seeding plot) and 3 zones (the top zone, the middle zone and the bottom zone) in each plot were treated with 3 replications on the experimented slope. Data such as vegetation coverage (%), soil hardness (MPa), temperature (
) and moisture (%) content were analyzed. The vegetation coverage was high in Early March seeding plot, medium in Mid-December, and low in Late January seeding plot. Early March seeding plot was effective in moisture content, soil hardness, and temperature for the growth of vegetation when compared to Late January seeding plot and Mid-December seeding plot. From the standpoint of coverage ratio of plant species, the coverage of Dianthus sinensis and Albizzia julibrissin were high in the Late January seeding plot whereas the coverage of Lotus corniculatus and Cool-season turfgrass were high in Early March seeding plot. These results indicated that the high vegetation coverage of Dianthus sinensis and Albizzia julibrissin in Early March seeding plot was caused by scarification during winter season. There was no difference observed in plant height regardless of seeding periods except in early surveying time of May and June after seeding. As far as each zone of the plot was concerned, the vegetation coverage was high. in the bottom zone, medium in the middle zone and low in the top zone. The bottom area of the experimented slope was high in moisture content when compared to the middle zone and the top zone.

Journal of the Korea Society of Environmental Restoration Technology, volume 12, issue 2, 2009, Pages 40~49
Urban park facilities and services offer a number of opportunities to fulfill individual, social, economic, and environmental benefits. Urban parks, provided through political measures as public goods, require balanced distribution in order to ensure social equity. The primary objectives of this study are to analyze the accessibility of urban parks and to examine whether urban parks are distributed equitably. GIS and statistical methods were used to investigate correlations between accessibility to neighborhood parks and socioeconomic status. As results, percentage of low-income population within the city was negatively related to park accessibility. Low-income dominated residential area, such as Sujeong-gu and Jungwon-gu have large low-income communities and less park accessibility compared with Bundang-gu, which are dominated by high-income residents. So, results from this study indicate that urban parks are not distributed equitably within Seongnam city. Therefore, creative strategies to provide urban parks for areas in need through the utilization of vacant lots, abandoned sites, and schools sites are necessary. Furthermore, budgetary priorities should be set to create new parks and revitalizing parks within the city's older neighborhoods are also needed.

Journal of the Korea Society of Environmental Restoration Technology, volume 12, issue 2, 2009, Pages 50~60
A spatial decision making process is needed when a local government tries to make polices and plans for eco-tourism in urban and regional site scale. This study aimed to suggest an assessment model to support spatial decision making on planning and making polices for eco-tourism. The model composes 6 stages of 'setting up ecogeographic territories'. 'value analysis method as ecotourism resources' 'synthetic assessing', 'grading values', 'selecting main resources for ecotourism' and 'spatial decision making support'. Applying the model to Shiheung city in Kyounggi province, validity was secured. By using the model, it was possible to make some decisions effectively such as selection of ecotourism resources, decision of the priorities of polices for ecotourism, and setting up the type of ecotourism to be introduced. In addition, by visualizing high valued resources and areas for ecotourism it w possible to support to make plans and policies effectively.

This study aims to analyze the current situation of and issues in the structure of urban neighborhood parks and park facility installation in cities in Gyeonggi-do. Then, based on its findings, plans to improve the space structure of the parks were examined and suggested to raise the city environment improvement function and green area base function of urban parks and fully satisfy users' needs for pleasant rest, recreation and cultural activities. The findings showed that, within parks, the area of grass where access was restricted reached about 24.4% in average. In other words, only 75.6% of total park area could be freely used by park visitors. As for an improvement plan, the grass area where access is limited may be converted into a gras area that can be freely used to raise the park use area, which currently stands only at 75.6%, to 100%. The result of cross analysis through Chi-Square Test regarding lawn use as well as regarding (dis)agreement with reduction of lawn, based on the investigation of cognition, showed a significant agreement of park users with reduction of green areas. Therefore it is considered that lawn space must be reduced according the result of the analysis, to set up plans for facility space that would meet the desires of users. The analysis of user behaviors revealed that many of them used square spaces and walks; therefore it is considered that re-structuring of space is necessary according to local characteristics. This study also made some policy suggestion. urban parks must be a base of city green areas to counter climate changes. When developing a park creation plan, a user demand survey must be conducted in advance. In addition. grass construction methods should be improved to tolerate foot pressure.

The traffic volume of Seoul is extremely high in comparison to other major cities in Korea, and the result has been harmful physical and mental exposure to pollution by Seoulites on a regular basis. The street air pollution is more important than the others, because the air pollution generated by street traffic directly impacts the health of nearby pedestrians. This problem requires urgent attention and resolution. Among the factors creating the air pollution originating from the street, is the configuration of streets, which have emerged as the most significant because it is related to air and pollutant dispersion. Therefore, this study was conducted under the assumption that street form affects the air quality. Study sites were classified by street characteristics, and air quality was analyzed in each class. Then the OSPM (Operational Street Pollution Model) was employed to simulate the relationship between street configuration and air quality of streets within the old city center and new city center in Seoul. After that this study analyzed the correlation between air pollution and the spatial configuration of urban streets (ex. street width, building height, building density, etc.) to determine their contributions to air pollution. The outcome of this study is as follows : First, the result that was derived from the correlation analysis between street configuration and air quality hewed that the air pollution of the street is influenced by the average height of building, width of the roads as well as traffic volume. On the roadside, the concentration level of
is mainly affected by the average height of building and the deviation of building height along the street and CO is affected by street width. The outcome of this study can be used as a basis for more sound urban design policies, and the promotion of desirable street environments for pedestrians.

Environmental pollution becomes a serious problem in urban areas. Moreover, densely constructed strictures can be problematic to cities due to the rising temperature they cause as well as the increasing accumulation of air pollutants they generate by interrupting airflow. In order to improve residential amenity, it is necessary to improve the thermal environment by preserving wind corridors. To do so requires consideration to important aspects such as building arrangement, scale, vegetation, and land cover, which all have an effect on wind corridors. In this study, a typical arrangement-complex, which is the primary form of housing in Korea, was selected as a case ENVI-met. As a result of empirical analysis, the optimal apartment-complex arrangement that is most suitable for mitigating urban heat-islands phenomenon was determined, The outcome of this study can be utilized as a planning technique for apartment-complex construction in consideration to type of buildings, scale of buildings, and land cover.

Journal of the Korea Society of Environmental Restoration Technology, volume 12, issue 2, 2009, Pages 95~105
Land Use Changes (LUCs) have effects on greenhouse gas emissions and carbon stocks in soil and vegetation. Therefore, predictions for LUC are very important for achieving quantitative targets of
reduction rates. Some research exists on carbon fluxes and carbon cycles to estimate carbon stocks in terrestrial ecosystems in Korea. However, these researches have limitations in terms of helping us understand future potential reductions of
that reflect the influence of LUC. The aim of this study is to analyze the reduction levels of
emissions while considering LUC scenarios that effect carbon fluxes for LCS basic study in the year 2030. In this study, a common approach to model the effects of LUC on carbon stocks is the use of CA-Markov technical process with LUC patterns in the past. Potential reduction of
is calculated by change of land use that contains different soil organic carbon, each land use type, and biomass in vegetation. An IPCC analytical method of natural carbon sink and coefficient results from previous study in Korea is used as a calculation method for potential reduction of
. As a result, 12,419 KtC will be reduced annually, which is 8.3% percent of 2005
emissions in Korea. This will result in 3,226 hundred million won of economic efficiency. In conclusion, conservation of natural carbon sinks is necessary even if the amount of potential reduction change is little.

Journal of the Korea Society of Environmental Restoration Technology, volume 12, issue 2, 2009, Pages 106~113
In this study, stability of the new gabion system with vegetation base materials was analysed. New gabion system with vegetation base materials is a new approach which has been developed to achieve lope stabilization and revegetation of forest road cut-slope by making the best use of advantages of gabion systems with vegetation base materials. Results from stability analysis are as follows. For the soil density, the angle of internal friction and unit weight of the rock fill was assumed to be
, respectively, the slope stability analysis showed that the new gabion system couldn't require any poles to fix it up, and could keep stable during both rainy and dry seasons. As the results of checks against overturning and sliding, the retaining wall with. the new gabion system could produce suitable factors of safety for overturning and sliding. Vegetation established on the surface of the new gabion systems indirectly can help to increase slope stability by prevention of surface erosion. Consequently, the new gabion system with vegetation base materials could achieve the desired effect on slope stabilization as much as existing gab ion system could do, and could promote rapid establishment of vegetation on cut-slopes.

Journal of the Korea Society of Environmental Restoration Technology, volume 12, issue 2, 2009, Pages 114~123
The objective of the study is to discuss the public value which inevitably required in the relation between city and transportation infrastructure and to suggest a public space at a transfer center which is a new type of transportation infrastructure. There has been little discourse on the public value of existing transportation infrastructure in the field of landscape architecture. Through this study. re-think of urban infrastructure from landscape architectural point of view will be examined. Through this study, three main considerations will be reflected in designing a transfer center, First, in a broad context, possibility of landscape architectural access toward transportation infrastructure should be considered. Secondly, unique characteristics of the transfer center system will be reflected on design process. Lastly, by analysing the site context of Dobongsan station P&R, design issues will be emerged. Transportation infrastructure is a field of urban life where people gather, exchange and do diverse activities. Design of transfer center through landscape architectural approach will be a meaningful reaction to the needs of public space in the urban infrastructures.
