An urban ecosystem is a complex system that includes social, economic and ecosystems. Therefore, it is important to consider its environmental capacity while developing a city plan. Most of the plans, however, consider only the social aspects, which fragments the green spaces and disturbs the movement of species. Sungnam has approximately 100 parks with unexecuted development plans and with great potential to contribute towards urban ecosystem enhancement. Therefore, this study applied network analysis to prioritize the development of city parks and contribute towards improving the green network, with Parus spp. as the target species. To compensate for the drawbacks of binary and possibility-based network analysis, this study included two indices, namely $BC^{PC}_K$, $BC^{IIC}_K$, $dPCconnector_k$ and $dIICconnector_k$. These indices make it possible to find patches that could play an important role in green network enhancement. The urban park with greater value gets a higher priority to be transformed into a park. Thus, our methodology could prove to be very useful in prioritizing the undeveloped parks, thereby supporting decision-making.

An important factor in assessing the beneficial qualities of a city's intersection spaces can be measured by examining a pedestrian's approach to the space and calculating the openness observed in the overall design of adjacent buildings. These spaces are influential, since they offer opportunities for pedestrians to spend time and take in views of the surrounding environment. The intersection of horizontal components in cities such as Bundang-si and Suwon-si can provide a sense of openness or greenness. We believe that there is a need for careful analysis and study of such components, as defined by designations in Bucheon-si research, and that this study can give important insights for future urban planning and design. When assessing the openness of an intersection, a key variable is the reported rate of perforation, which factors into the greenness of a space. Because of the large and varied scope of this research, this rate is highly variable, as there were many differences between each site. In descending order of average ratios: Seongnam-si, 41.79% > Bucheon-si, 35.40% > Suwon-si, 30.42%. The data compared for each city was divided into study sites selected at downtown locations as well as in urban outskirts. Openness and greenness were analyzed at each downtown and outskirt site. A summary of the results shows a decreased openness average of -2.63% in downtown locations versus outskirt. The greenness ratios in urban outskirt areas were 4.86% greater than downtown locations on average. As it relates to the results of this analysis of openness, the comprehensive property zoning for each city was determined as a ratio of residential to commercial designations. This study analyzes view points within urban cross intersections in the downtown landscape. It presents basic data and research directions to promote a better environment with regard to openness, and consists of an analysis of the relationship between a variety of physical components.

Roadside greenery in the city is not only a means of reducing fine dust, but also an indispensable element of the city in various aspects such as improvement of urban thermal environment, noise reduction, ecosystem connectivity, and aesthetics. However, in studies dealing with the effect of reducing fine dust through trees in existing urban spaces, microscopic aspects such as the adsorption effect of plants were dealt with, structural changes such as the width of urban buildings and streets, and the presence or absence of trees, Impact studies that reflect the actual form of In this study, the effect of greenery composition applicable to urban space on PM2.5 was simulated through the microclimate epidemiologic model ENVI-met, and field measurements were performed in parallel to verify the results. In addition, by analyzing the results of fine dust background concentration, wind speed, and leaf area index, the sensitivity to major influencing variables was tested. As a result of the study, it was confirmed that the fine dust reduction effect was the highest in the case with a high planting amount, and the reduction effect was the greatest at a low background concentration. Based on this, the cost of planting street green areas and the effect of reducing PM2.5 were compared. The results of this study can contribute as a basis for considering the effect of pedestrian space on air quality when planning and designing street green spaces.

Recently, many people can experience the virtual space by smartphone, and they use many games. In particular, this change has great implications in the collaborative and communicative planning paradigm, which is residents' participation and agreement becoming important in community making and urban design. This study analyze the case of the five virtual space games about community making and urban design, and examine the related regal system. Game users can construct roads, houses, buildings and facilities in the virtual city. Then, they create profit, and promote the growth of virtual city. In these games, construction elements are classified residential, commercial, industrial, parks, green spaces, public building, and roads. But these elements does not identified clearly, and they mixed. By analyzing of related regal system, these games focus on the individual buildings, spaces, and facilities rather than considering the terms of urban planning. To complement the virtual space game with the aspects of urban planning, these games can encourage the participation capability and enhance the communication skills of citizens.

21세기 들어 공원 및 오픈스페이스 계획은 기존의 양적인 성장, 생태적 측면 그리고 여가적 측면 등 단편적 기능에 집중해오던 것에서 다양한 혜택을 가져오는 다기능과 함께 오픈스페이스와 녹지 등의 연결성을 강조하는 그린 인프라스트럭처로 확대되고 있는 실정이다. 런던의 경우, 그린 인프라스트럭처는 기존의 물리적 그리고 사회 기반시설과 함께 핵심 기반시설 중의 하나로 인식되고 있으며 이론적 접근을 통해 그린 인프라스트럭처 계획을 지속적으로 개발하고, 법적 도시계획 속에 반영되어 지방 차원에서 실질적인 공간계획으로 구현되고 있다. 이에 본 연구는 영국의 법정도시계획인 런던플랜 속에서 그린 인프라스트럭처 정책의 변화 발전과 세분화된 전략적 실행 계획인 그린그리드 계획 그리고 지역계획에 반영된 정책의 동향과 특징과 시사점을 다루었다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 중앙 정부, 광역지방정부 그리고 지방정부가 명확한 역할 분담을 하고 있다. 국가계획정책체계인 NPPF, 그리고 광역런던기구의 런던플랜에 준하여 로컬플랜을 수립하고 있어 중앙정부의 정책목표가 지방정부의 개발계획에 일관성 있게 반영되는 시행 체계를 구축하고 있다. 그린 인프라스트럭처가 정책적으로 높은 비율로 지방정부의 로컬플랜에 반영되고 있어 이를 뒷받침하고 있다. 둘째, 광역계획인 런던플랜을 통하여 그린 인프라스트럭처와 관련된 정책 그리고 실천전략으로서 그린그리드 계획을 일관되게 확대 발전시키고 있다. 또한 정권과 관계없이 지속적이고 일관되게 추진되고 있으며 시대의 흐름에 맞게 보다 발전되고 강화되면서 장기적 실행계획으로 실현되고 있다. 셋째, 광역런던기구는 선언적 정책에 머무르지 않고 런던 시장이 직접 운영하는 지원 프로그램을 통하여 지방정부에서의 실행을 지원하고 있으며 파트너쉽으로 유도하고 지원하는 방식을 통해 정책을 실현하고 있다. 근래 서울시도 공원과 녹지정책에 있어 발전을 가져왔지만 선언적 정책에 머무르지 않고 영국 런던과 같이 정권과 관계없이 지속적이고 일관되게 추진되는 정책과 장기적으로 실천되고 있는 계획 사례의 검토는 우리에게 주는 시사점이 크다.

In order to prepare a basis for ecological restoration of the Seoul Metropolitan area, ecological diagnoses on soil physico-chemical properties and vegetation structure were carried out. Land use patterns, actual vegetation, and biotope patterns were also investigated based on aerial photograph interpretation and field checks. I formulated landscape elements overlaying those data and evaluated the ecological value of each element. Soil pollution was evaluated by analyzing soil samples collected in each grid on the mesh map, divided by 2km $\times$ 2km intervals. Soil samples were collected in forests or grasslands escaped from direct human interference. Soil pollution evaluated from pH, and SO$_4$, Ca, Mg, and Al contents of soil was more severe in the urban outskirts than in the urban center. Those soil environmental factors showed significant correlation with each other. Vegetation in the urban area was different in species composition from that in suburban areas and showed lower diversity compared with that in the suburban areas. Successional process investigated by population structure of major species also showed a difference. That is, successional trend was normal in suburban areas, but that in urban areas showed a retrogressive pattern. The landscape ecological map of Seoul indicates that the urban center lacks vegetation and greenery space is restricted in urban outskirts. Such an uneven distribution of vegetation has caused a specific urban climate and thereby contributed to aggravation of air and soil pollution, furthermore causing vegetation decline. From this result, it was estimated that such uneven distribution of vegetation functioned as a trigger factor to deteriorate the urban environment. I suggested, therefore, a restoration plan based on landscape ecological principles, which emphasizes connectivity and even distribution of green areas throughout the whole area of the Seoul to solve this complex environmental problem. In this restoration plan, first of all, I decided the priority order for connection of the fragmented greenery spaces based on the distances from the core reserves comprised of green belt and rivers, which play roles as habitats of wildlife as well as for improvement of urban environment. Next, I prepared methods to restore each landscape element included in the paths of green network to be constructed in the future on the bases of such preferential order. Rivers and roads, which hold good connectivity, were chosen as elements to play important roles in constructing green network by linking the fragmented greenery spaces.
