This study focused on the changes of residential area around the linear park. The goal of this study is to determine the value of linear park at the view of residents and discover the interaction between the linear park and the residential area around it. To investigate this goal, the researcher chose case sites, the regenerated linear park and the uncovered stream park. This study analyzed the site around the linear parks with four points of view, the organization of urban Fabric, architecture, the economic value of the site and the behavior of residents. This research adopted several research methodologies like aerial photograph analysis, road-view analysis, paper research, and field study, observation, and expert interview to approach as both quantitative and qualitative analysis. With that variation characteristic, the researcher determines the influence of linear park through the residential area around them. As the result, linear park gives positive effects of running sustainable residential area around them and acting as the pivot for the residential area. Also for the future, designers must consider this interactive relation between the linear park and residential area with the wide point of view.

The retaining wall is a structure which was made for changing land form in many construction. The first role of the retaining wall is to maintain the slope stability. But recently, the amount of retaining wall have been increasing because of the expansion of construction works and the amenity of urban environment have been decreasing because of environmental destruction and the scenic heterogeneity. So we should consider the slope stability and ecological stability at the same time. The purpose of this study is to develop the retaining wall revegetation technology using the Eco-Stone, the structure of co-satisfying which included the slope stability and the revegetation effect. Eco-Stone is a structure which has high stability for earth pressure, settlement and drainage. And cost and term of construction works also have been decreased. Eco-Stone structure is one of factors composing the ecological network which is harmonize with surrounding environment. In this way, it is expected that the ecological habitats of various species would be restored.

Since 1960s urban streams in Seoul have been dried and polluted because of urbanization. So, these devastated urban stream environment need to be restored for the better life of residents. Since 1995 stream restoration project which is called Natural-Style Stream Project have begun. However, some projects focused on the restoration of park-style open space rather than restoration of stream environment. As a result there are some stream landscapes to be improved. Therefore, this study aims to investigate the current status of urban stream landscape after Natural Style Stream Project and to propose the alternatives for the urban stream landscape improvement. The study site is Yangjae stream, Seoul.

The objectives of this study is to find problems in the legal and institutional background on our information system for soil contaminated sites. To achieve this abjective, we compared our system with those of federal and New Jersey state governments of the United States. We found that we have no comprehensive guideline on how various information from the contaminated sites should be manipulated. In our system, some regulations on information management were found only in a few prescriptions on detection, detailed investigation, and remediation phases. However, we found that provisions, detailed procedures, and related guidelines for the information management are provided in tile case of the federal and New Jersey state governments. Also, public involvement and disclosure of tile information for the remediation procedure are designated in their legal systems.

하천 수위 유지나 용수 취수 목적으로 사용되는 보는 현재 국내에 약 18,000여개 정도가 설치되어 있으며, 대부분 용수 공급 시설로 이용되고 있다. 하천에 보가 축조되면 하천생태통로의 차단, 보 상류부 수질 악화, 수변 생물서식처의 변화, 경관 훼손 등의 문제가 발생하게 되지만, 이를 해결하기 위한 방법은 극히 일부 보에 생태 통로로서 설치되는 어도 외에는 거의 혀는 실정이다. 최근 농경지 도시화, 경작 방식의 변화, 취수시설물 통폐합, 시설 노후화 등으로 매년 수십 개 이상의 보가 폐기되고 있으나, 폐기된 보는 천거되지 않고 하천에 존치되어 여전히 문제를 발생시키고 있다. 외국의 경우에도 기능을 상실한 보/소형 댐을 보 철거 의사 결정 과정을 통해서 철거를 결정한 후 철거를 시행하고 있으며, 기 철거 사례를 분석한 결과를 바탕으로 과학적이고 공학적인 보 철거 우선 순위 결정 방법을 제시하기 위해서 노력하고 있다. 국내의 경우 아직 보 철거를 통한 환경 복원이 일반화 되어 있지는 않지만, 그 필요성이 점차 증가하고 있으며, 이를 위해 국내 환경에 적합한 보 철거 의사 결정 과정 마련을 위한 연구 필요성이 같이 증가하고 있다. 본 연구는 보 철거를 통한 하천생태통로 복원 기술 개발을 위한 기초 연구의 일환으로 보 기능 저하 요인 파악을 위해 각 주요 수계에 설치된 보를 현장 조사하였다. 조사 결과 기능이 저하 중인 보로 판단되는 보는 분석하여 유형화하고, 요인별로 대표적인 예를 제시하여 이후 판단 자료로 활용할 수 있도록 하였다.

This study for development of close-to nature revetment techniques is conducted to rehabilitate disturbed stream ecosystem. For this objective, the experimental reach as on-site dimonstrated research was set up in Hakyoul, the Yangjaech'on from Oct. 1995 to Nov. 1996. Special emphasis on the developing process of the design of revetments was given to geomorphic character of 3 types of low flow channel bank: point bar, attack point and shallow bay. Each revetment was developed with the consideration on revegetation of emergent plants. And designed techniques were applied to the experimental reach, and were evaluated with monitoring for 1 year. As a result of the process, the experiment suggested ecological alternatives to enhance technical feasibility and to replace the conventional river-work.

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.

Ecological restoration is regarded as a major strategy for preventing biodiversity loss and thereby enhancing ecosystem service. This study was performed to evaluate ecosystem service value that the restored ecosystem provides. Ecosystem service was evaluated for provisioning and regulating services. The former service was evaluated by comparing similarities in a viewpoint of floristic composition to the reference site between the restored and the unrestored sites. Species composition of the restored site was found to be more similar to the reference site than that of the unrestored site and thereby restoration practice contributed for enhancing the provisioning service. Regulating service was evaluated based on microclimate control, soil amelioration, and improvement of water holding capacity. The value of ecosystem services in terms of microclimate control, soil amelioration, and improvement of water holding capacity was higher in the restored site than in the unrestored site. In consequence, ecological restoration of coal mine spoils contributed for enhancing the ecosystem service value of the corresponding site and thereby is rewarding the cost invested for restoration.

도시화, 산업화로 인해 도시는 그 주변지역보다 기온이 높은 도시열섬 현상이 발생하고 있으며 이는 인간 활동에 의한 인공폐열 배출량의 증가에 기인한다. 이러한 인간 활동에 의한 도시기온의 변화는 도심과 농촌지역의 차이로 인한 공간적 변이와 아울러 주중과 주간에 기온 차이가 발생하는 시간적 변이를 포함하고 있으나 도시열섬현상의 공간적 변이에 의한 연구에 비해 시간적 변이에 의한 연구는 많이 수행되고 있지 않다. 본 연구에서는 서울 도심의 주중과 주말의 기온차이를 다년간 관측을 통하여 주중과 주말의 주간 변동의 특성을 파악하여 도시 기온의 시간적 변이를 파악하기 위하여 서울시 강남구를 사례로 2007년 10월 31일부터 2010년 12월 11일까지 약 3년간 관측한 자료를 이용하여 분석한 결과 5개 관측지점 모두 주중(weekday)이 주말보다 $1.6{\sim}1.7^{\circ}C$ 기온이 더 높았으며 이는 주중에 도시 내에서 방출하는 인공폐열의 양이 더 많음을 의미하며 고밀도지역은 냉난방수요가 많아 토지이용에 따라 기온의 차가 크므로 이를 저감시키기 위한 도시 및 조경계획이 필요하다.

The purpose of this study is to examine the ecologically suitable restoration characteristics in riparian slopes constructed by continuous fiber soil reinforced system (Geofiber system) which does not contain the concrete materials. The findings are as follows : (1) as the tested soil was not washed away by rainfalls and floods, Geofiber could replace the concrete wall and gravity stone net bag technique from the civil engineering structural point of view; (2) after one year of the construction, it was monitored that land cover ratio was 80-90%, which indirectly shows that vegetation is safely maintained; and (3) at the same time, 5-8 flora species were found in each test grid and more importantly dominant species have been moved from alien species to native herbaceous plants. From the above findings, Geofiber system is recommendable to restore the riparian slopes in terms of stability and natural landscape points. However, a long term monitering is needed considering flora succession process in a given environment as well as suitability tests should be carried out through the comparative investigations in other environments.
