공원법이 제정된 이후 40여년 동안 어려운 여건 속에서 공원녹지분야의 양적 발전이 이루어져 왔다면 21세기에는 질적 발전이 이루어져야 되겠다. 도시계획의 틀속에서 최소한의 공원녹지가 지정, 조성되어 관리되고 있으나 지정된 공원녹지가 사유지인 곳이 많기 때문에 공원조성 뿐만 아니라 적절한 녹지관리가 어려워 자연보호식 녹지보호나 식묵행사에 그치고 있는 실정이다. 한편 변화하는 시민 요구와 도시환경에 발 맞추어 도시환경보전과 경관보전을 위한 녹지체계 수립이나 관리목표를 세분화하지 못하고 체계적이고 선진적인 도시녹지관리가 이루어지지 못하고 있는 실정이다. 체계적이고도 질적인 도시농지관리로 전환하기 위해서는 저확한 녹지실태 조사와 수요를 토대로 녹지체계정립, 녹지종류의 조정, 녹지종류별 생태학적 관리목표설정 및 세부지침이 선행되어야 한다.

Areas around of National Park have been severed eco-corridor of wildlife due to urban expansion and development. Habitats have been fragmented into small pieces. Habitat fragmentation reduces the biodiversity of organisms because the exchange loss and inbreeding of wild fauna and flora. The main cause of the fragmentation of ecological networks in areas around of Moodeungsan National Park are are that the cemetery, cutting of mountain, roads, public parking lots, mountain encroachment by land, urban infrastructure, electric transmission towers, urban area. Area around of National Park must be equipped with ecological networks through an ecological design that can communicate with each other in the national park and urban areas.

Rapid industrialization and economic growth have led to serious problems including reduced open space, environmental degradation, traffic congestion, and urban sprawl. These problems have been exacerbated by the absence of effective conservation and governance, and have resulted in various social conflicts. In response to these challenges, many scholar and government hope to achieve sustainable development through the establishment and management of environment-friendly planning. For this purpose, we would like to analyze functional change for ecosystem by future land-use/cover changes in South Korea. Toward this goal, we predicted land-use/cover changes from 2010 to 2060 using the future population of Statistics Korea and urban growth probability map created by logistic regression analysis and analyzed ecosystem service value using costanza's coefficient. In the case of scenario 1, ecosystem service value represented 6,783~7,092 million USD. In the case of scenario 2, ecosystem represented 6,775~7,089 million USD, 2.9~7.6 million USD decreased compared by scenario 1. This was the result of area reduction for farmland and wetland which have high environmental value relatively according to urban growth by development point of view. The results of this analysis indicate that environmentally sustainable systems and urban development must be applied to achieve sustainable development and environmental protection. Quantitative analysis of environmental values in accordance with environmental policy can help inform the decisions of policy makers and urban developers. Furthermore, forecasting urban growth based on future demand will provide more precise predictive analysis.

Studies for demarcation of urban areas by ecological type have been developed, but the demarcation of urban areas by ecological perception is thus far dependent on artificial land use. Therefore, the purpose of this study is to find factors that account for the urban area ecosystems by surveying a variety of ecosystem factors. By land use type, the urban area of Gangdong District, Seoul was defined. Then ecological factors in each polygon were surveyed. Ecological factors are associated with energy use(building coverage ratio, floor area ratio and ground temperature), water circulation(biotope area factors and impermeable pave ratio) and biological diversity(bird appearance index and green area ratio). The correlation between each factor was analyzed. The results indicate that urban ground temperature is divided into three groups(high, middle and low) by the biotope area factor. The bird population is divided into two groups(abundant and scarce) by the green area ratio. Therefore, demarcating the urban areas by ecological type is applicable to the biotope area factor and green area ratio.

공원녹지가 군시내에서 수행하고 있는 역할에 대해 학자들은 크게 '주민을 위한 위락공간으로서의 역할' '도시구조를 이루는 한 요소로서의 역할' 그리고 '도시 생태계의 기반으로서의 역할'등 크게 세가지로 구분하고 있다. 본 연구는 대도시 주민들이 인식하고 있는 도시공원녹지의 역할을 그들의 이용과 가치관을 중심으로 설문조사에 기초한 결과의 일부이다. 조사에 의하면, 주민들은 대개 공원녹지를 그들의 위락공간을 위한 장소로서 인식하고 그 역할에 동의하고 있는 것으로 나타났다. 최근, 도시·조경계획분야에서 크게 논의되고 있는 생태학적 개념에 근거한 도시공원녹지의 '도시내 자연'으로서의 역할에 대한 주민의 인식이 전문가들의 열의에 배해 많이 높지 않음을 보여 주었다. 그러나 이는 위락공간으로서 역할 다음으로 중요도가 인식되고 있는 만큼 도시내 자연으로서의 공원녹지 역할을 높이기 위해서 학자들 사이에 구체적인 논의와 실증적인 연구가 뒤따라야 할 뿐만 아니라 주민들의 의사와 합의가 있어야 할 것으로 생각된다. 한편 도시공원녹지의 역할에 대해서는 도시주민의 사회적인 변수 특히 성, 교육수준, 임금수준 등에 따라 차이가 있는 것으로 나타나 도시공원녹지 계획시 이들 변수에 대한 고려가 있어야 할 것이다.

In this study, among the construction-type parks in Gangdong-gu, targeting parks with high environmental and ecological value located on the urban green axis, a plan was prepared for the ecological renewal of urban parks, and a design that applied to them was proposed. The renewal target site was selected by analyzing the general condition of Gangdong-gu and urban parks, the land use and green area ratio, park green area, and the green axis of Gangdong-gu. Gangdong-gu has 54 parks, including 2 neighborhood parks and 52 children's parks. In the first stage of the current status review, 17 parks were extracted through locational value analysis, such as location and adjacency to the natural axis and green axis. In the second stage, eight parks were selected among the first-stage extraction parks based on the ratio of green spaces and open spaces within each park service area. In the third stage, two of the second stage extraction parks were selected based on whether the legal standard of the park area was met, and in the fourth stage, one of the third stage extraction parks was selected through an aging survey of the park. As for the urban ecological status of the renewal target site, the status of land use in the aspect of entropy reduction, the status of soil cover in the aspect of water circulation, and the status of planting structure in the aspect of biodiversity were investigated. As for the status of the three renewal sites, the green area was insufficient at 18.3-45.3%, and the facility area was 54.7%-81.7%, which was judged to have low urban temperature reduction effects. The impervious pavement area accounted for 34.5% to 48.9% of the park area, accounting for most of the facility area, and it was judged that the water circulation function was insufficient. The planting structure consisted of a single layer and a double layer structure, and although the tree layer was good, the lower vegetation was poor, and there was no planting site of edible plants or large hardwood trees, so the biodiversity was low. After the ecological renewal design of Seonrin Children's Park, Dangmal Children's Park, and Saemmul Children's Park, which were selected as the renewal targets in this study, the ecological area ratio of each park increased by 1.4 to 3 times than before the renewal. If the urban parks located on the urban green axis are examined from the perspective of the urban ecosystem and renewed ecologically, it is judged that the expected effect will be high in reducing entropy, improving water circulation, and laying the foundation for biodiversity in terms of the urban ecosystem.

This study examined ecological network change affected by the 2020 invalidation of decisions on urban parks with a focus on Busan. The analyses were conducted to five scenarios using FRAGSTATS. The green space in scenario 1 assuming all development for unexecuted urban park would decrease by 7,339.75 ha compared to scenario 5, which assumes the entire conservation of unexecuted urban parks, and the fragmentation of the ecological space in scenario 1 increased. In scenario 1, 8.06% of the total area of core habitats and 28.23% of connectivity would decrease. However, scenario 3, which assumes the conservation of environmentally sensitive areas of unexecuted urban parks, can achieve 94% of green space and 95.6% of the connectivity of the scenario 5. Scenario 3 has effects similar to scenario 5 in terms of defragmentation. Thus, conservation of environmentally sensitive areas in parks is critical and effective in maintaining ecological networks.

The development of civilization is in line with evolution of cities and transportation technology caused by industrialization. Up to now, a city has been developed owing to transportation cost reduction and needs for land utilization as a limited core business district. Continuous increase of urban population density has accompanied by lots of problems socioeconomically such as rise of land value, traffic congestion, gap between the rich and poor, air pollution, etc. Those issues are difficult to be solved in existing city ecosystem. However, a clue for solving the problems could be found in there. The design of Seoul mid-night bus route was from analysis of movement of people in the rural area by using ICT so that a city ecosystem should be firstly analyzed for solving rural issues. If the cause of those is found, big data platform construction is required to raise the life quality of citizen and the problems could be solved. Big data should be located in the middle of the platform connected with every element of city based on ICT for real-time collection, analysis and application. This paper addresses construction of big data platform and its application for sustainable smart city.
