Natural disturbances and human development can cause habitat fragmentation. Plant and wildlife can become isolated, and habitat fragmentation and shrinkage have been recognized as a key issue facing the conservation of biological diversity. However, eco-corridors can alleviate the problem by providing linkages between isolated patches. The purpose of this study is to plan the eco-corridor for connecting urban forest via the urban stream with low cost and to restore the ecosystem. The results were as follows (1) Falco subbuteo, and Dryocopus martius inhabit in the study site. They are protected species designated by Korean Ministry of Environment. Thus the study site should be preserved as urban wildlife habitat species biodiversity (2) If the biodiversity of the study site is maintained properly, the eco-corridor can be constructed with low cost.

In this study, soundscape was analyzed through physical measurement and social surveys. The results showed that, soundscape components were related to functional partitions and tourist activities, at the same time influenced by ambient noise. The sound pressure levels showed daily regular changes. Semantic differential analysis showed that the evaluation of the soundscape in urban park was rather complicated. It was still possible to identify major factors including relaxation, spatiality and environment. The results provided theoretical basis for improving urban park soundscape, and called attention to this problem.

Recently, summer high temperature events caused by climate change and urban heat island phenomenon have become a serious social problem around the world. Urban areas have low albedo and huge heat storage, resulting in higher temperatures and longer lasting characteristics. To effectively consider the urban heat island measures, it is important to quantitatively grasp the impact of urban high temperatures on the society. Until now, the study of urban heat island phenomenon had been carried out focusing only on the effects of urban high temperature on human health (such as heat stroke and sleep disturbance). In this study, we focus on the effect of urban heat island phenomenon on air pollution. In particular, the relationship between high temperature phenomena in urban areas during summer and the concentration of photochemical oxidant is investigated. High concentrations of ozone during summer are confirmed to coincide with a day when the causative substances (NO2,VOCs) are high in urban areas during the early morning hours. Further, it is noted that the night urban heat island intensity is large.. Finally, although the concentration of other air pollutants has been decreasing in the long term, the concentration of photochemical oxidant gradually increases in Daegu.

If environmental aesthetics contains the whole area of grand beauty of nature and the meaning of the urban landscape, the urban landscape is defined 'fine view of urban, or beautiful sight' therefore, we must look for the wary to introduce and solve the aesthetic problem with a new paradym of the urban landscape. Such environmental aesthetics as to seek a new planning for the urban landscape can provide a new meaning for urban environment design by extracting design elements of street furniture resulted form aesthetic evaluation in context of formation aesthetics to review the aesthetic value and substance, and explain aesthetic experience, and explain aesthetic experience of urban the landscape.

Rapid urbanization poses three major problems in urban streams. The first problem is the reduction of soil wetting from rainfall as the impervious area increases. Decrease in soil wetting causes serious distortion in the water cycle of urban streams. The second problem is the increase of non-point sources pollutants by urban land use, and the third problem is the combined sewer overflows in the old city center. Increased non-point sources pollutants and combined sewer overflows are associated with water cycle distortion, which increases water pollution in urban streams. In this study, EPA SWMM was constructed for the Busan Oncheon-stream watershed in order to suggest solutions for these three problems, and the bio-retention cells installation project was planned by benchmarking the actual projects in New York City. Water cycle improvement and reduction of non-point sources pollutants and combined sewer overflows for each project scenario were analyzed together with required budgets.

As air pollution has emerged as one of the most pressing urban environmental concerns, many studies have investigated the influence of air pollutants(ex: $O^3$, $NO^2$, $SO^2$, Acid rain, etc.) on roadside trees and urban grove. In Korea, population density started to increase since the industrialization. Since dense population aggravates our living conditions, it's very important for us to preserve and keep a lively and refreshing nature in order to live with green nature in harmony under the current artificial environment-dominating world. In metropolitan cities, the production of pollutants increases in proportion to population growth. The vehicle exhaust gas and air pollutants from cooling and heating systems have been the major causes of acid rain. Furthermore, tire particles which are naturally produced by tire wearing on roads and other toxic substances in exhaust gas have caused a problem in human health directly and indirectly. In fact, a lot of studies have analyzed air pollution, roadside trees and plants in Korea. However, they are mostly limited to covering the influence of air pollution on the growth of plants. No paper has clearly explained why air pollution-resistant or-vulnerable species has shown different reactions yet. Even though a lot of urban roadside trees have died or stopped to grow from time to time, this kind of problem has not been properly examined. This paper is aimed to comparatively analyze physio-ecological characteristic such as photosynthesis, chlorophyll contents, soil volume water figure out their relationship with environmental factors against the expanding roadside trees in Cheong-ju, and provide basic data for management of roadside trees and elaboration of urban environment preservation policies.

Road traffic noise is closely related with urban forms and urban components, such as population, building, traffic and land-use, etc. Hence, it is possible to minimize the noise exposure problem depending on how to plan new town or urban planning alteration. This paper provides ways to apply for urban planning in consideration of noise exposure through road traffic noise estimation for alteration of small-scale urban form. Spatial autoregressive model from the former study is used as statistical model for noise simulation. The simulation results by the spatial statistical model are compared with those by the engineering program-based modeling for 5 scenarios of small-scale urban form alteration. The error from the limitation of containing informations inside the grid cell and the difficulties of reflecting acoustic phenomena exists. Nevertheless, in the stage of preliminary design, the use of the statistical models that have been estimated well could be useful in time and economically.

Waste disposal problem is one of the most important social welfare indicators in urban area, because the volume of waste generated from urban area is remarkable. So far most waste of Seoul has been disposed at landfills. However, this landifill disposal method is confronted with several difficulties in recent. As public concern on environmental problem increases and autonomy system is settled down, local community people of the landfills refuse to receive the waste produced other places any more. It brought reginal confliction problem between waste sending and receiving by refusing to accept waste from certain region. Furthermore, it is difficult to find another place to fill up the waste, while the existing landfiis is reached at the limit in the near future. In terms of environmental aspects landfill method is not the best way to dispose waste. It contaminates the soil and ground/underground water by leaking water containing many serious pollutants as well as offensive oder. In terms of equity, this waste disposal method is not fair. Environmental pollution causes damage to residence near to the landfills, while the waste produced other places. In order to satisfy the equity aspect, the waste generated a region should be disposed within the region. Incineration of Waste has been provided as the alternative. Government plans to construct waste incinerator in every anatomy, so the waste produced by local community is disposed within their local autonomous area. However, the location decision is not easy, since waste incinerator is one of the facilities to the community people. We can not apply the existing location models for this problem, because they show strong NIMBY phenomenon for the location. The location of waste incinerator should be determined very carefully with consideration of various location factors and criteria. This study proposes a methodology for determining the location of the waste incinerators by utilizing GIS, which is a power research tool for location decision where various geographical factors related. We drive the location factors which should be considered in the determination of waste incinerators. They involve environmental, socio-economic, and institutional factors. In first, we eliminate the area which is located within the environmental location criteria such as slope, fault line, distance to river, and then eliminate ares which is conflict with the social and institutional criteria.

After UNECD(United Nations Conference of Environment and Development) in 1992, ESSD (Environmental Sound and Sustainable Development) is an important concept of urban planning in Korea. The introducing environmental assessment system of urban planning and the district unit planning system were representative cases. In this process, Landchaftplanung(ecological landscape planning) was introduced from Germany. This study was executed for applying ecological landscape planning to Eunpyung New Town in Seoul city, and analyzing the problem to apply this system. The process of ecological landscape planning was followed to (1) the site survey, (2) the analysis and assessment of survey data, (3) the establishing ecological landscape planning. Three master architects participated in all investigations. The major fields of them were landscape architecture, architecture, and urban planning. Master Architects helped many aspects. In conclusion, ecological landscape planning was feasible to be applied to develop other New Town in Korea. However the mediation system is very weak, if different situations are confronted with ecological landscape plan and land use plan in the operative legal framework of Korea. Thus, the legislation of mediation system is necessary for an establishment of ecological landscape planning.

Modern cities are weak in traditional culture with the lack of characteristics and the problem of environmental deterioration. As the important carrier of urban culture, landscape architecture should be responsible for solving these problems. The urban need is paid much attention in the design of South Bank Linear Park in Meizhou city. Following the principle of inheriting and developing urban traditional culture, the design of the whole park is integrated with Hakka culture in Meizhou, which forms the landscape with local features and modern landscape architecture culture, and promotes the urban culture construction.
