  • Due to its speciality, Johannesburg has drawn wide attention from the international academia, which the existing urban theory cannot easily explain. This paper focuses on the spatial pattern of Johannesburg, and finds that it is highly fragmented: first North-South Division due to apartheid and gold mining, secondly, the continuous sprawl due to population densification, and thirdly formation of city-region due to the fill-in spatial policy. The fragmented spatial pattern undermines the social integration and weakens the potential economic sustainability, which make the balanced multi-core spatial pattern inevitable under the influence of the international planning thought. The Johannesburg's spatial transformation comes not only from social integration, but also from the development vison of world-class status of an African city. In reality, since the collapse of apartheid, the municipal government has released series of strategic planning in different executive phase. These different plannings unanimously focus on the world class status although since 2008, the social inclusiveness is more emphasized. Thus, Johannesburg implements some spatial policies, as promoting the corridor of freedom, identifying the key nodes in the city then developing with high density, implementing the in-filling policy, managing the urban growth boundary, effectively preserving the natural system. However, the industrial structure in Johannesburg is already quite high-ended which cannot produce many jobs and also require much investment in advanced infrastructure. Thus, the strategic goals of world-class status of an African city and social inclusiveness which really need widely shared public services to some extent are in tension. After evaluation, we can see that spatial transformation is quite limited. Obviously spatial transformation largely depends on the social-economy. The population is still in flow. In this sense Johannesburg must energetically support the employment-based industry, effectively control the spatial sprawl and carry out institutional innovation which further incentive investment, gradually build an integrated regional governance. In general, how Johannesburg combines globalization and its own condition is still worth thinking in both theory and practice.

  • 본 연구는 부산시 북구 화명2동 대천마을과 대천천네트워크를 사례로 도시화로 인해 야기된 분절화, 위계화가 공간구조만이 아니라 구성원의 구성에 미치는 영향을 살펴보고 대천천네트워크를 통해 분절된 공간을 넘어서는 구성원들 간의 연대와 그 내면에 작동하는 가치를 찾아보고자 하였다. 1980~1990년대 대규모 택지개발사업으로 인해 대천마을은 농촌에서 도시로 급속하게 전환되었다. 이 과정에서 하나였던 공간은 대천마을과 아파트단지지역으로 분절되었다. 공간의 분절에 따라 주민들의 구성도 노년층 토착민과 청장년층 이주민으로 나눠지게 되었다. 그러나 두 지역의 단체들을 연대하여 만든 대천천네트워크를 통해 주민들은 지역의 당면한 문제들을 해결해 낼 수 있었고 아울러 자신들의 거주공간을 분절되고 위계된 공간이 아니라 함께 살아가야 할 삶터이자 하나의 마을로 인식하게 되었다. 대천천네트워크는 공간적 분화를 넘어 토착민과 이주민을 엮어주는 운동이자 관계망의 역할을 수행하였고 나아가 '공생'의 가치로 하나의 공동체를 만들어 나갈 수 있는 계기가 되었다.

  • 도시의 성장이 경제발전에 긍정적인 영향을 가져온다는 점에도 불구하고 아직까지 우리나라에서는 도시의 구조를 파악하기 위한 연구가 상당히 미흡한 실정이다. 본고에서는 도시 간 규모의 분포구조와 도시 내 인구밀도함수 등을 통한 내적구조를 새로이 정의한 광역도시통계권을 기준으로 살펴보았다. 먼저, 도시순위규모법칙의 계수분석을 통한 한국의 광역도시통계권 간 인구분포구조를 비교하였다. 한국은 서울광역도시통계권의 규모가 상대적으로 매우 크며 행정구역 상의 인구규모 분포보다 실질적으로 훨씬 집중되어 있다. 이는 서울광역도시통계권이 상대적으로 지나치게 거대하든가 혹은 부산이나 대구, 대전 광역도시통계권의 성장이 상대적으로 뒤떨어진 것으로 해석된다. 한편 지리정보프로그램(Arc GIS)을 이용하여 도시 내의 중심상업지역에서부터의 거리에 따른 인구밀도함수나 부동산가격 등을 통하여 도시의 내적구조를 분석하였다. 표준도시모델(Standard Urban Model)에 따르면 일반적으로 도심에서 외곽으로 갈수록 인구밀도와 부동산 가격이 하락하는 형태를 보이지만 서울광역도시통계권의 외곽에서는 상대적으로 다른 광역도시통계권과는 달리 그 하향곡선이 무척 완만하였고, 이는 결국 도심확산(Urban Sprawl)이 활발히 일어나고 있음을 의미한다. 한편, 울산, 광주권, 그리고 수원-화성-오산권에서 인구분포와 고용분포 간의 공간적 불일치 정도가 큰 편이고 대전권과 인천권에서 작은 편으로 나타났다. 이러한 도시의 구조에 대한 분석은 지역정책의 운용에 있어서 많은 시사점을 줄 수 있다.

  • Every year in Europe, soils covering an area larger than the city of Berlin are lost to urban sprawl and transport infrastructure. Soil sealing causes an irreversible loss of the biological functions of soil. As water can neither infiltrate nor evaporate, water runoff increases, sometimes leading to catastrophic floods. Landscapes are fragmented and habitats become too small or too isolated to support certain species. In addition, the food production potential of land is lost forever. There is an urgent need to use this valuable resource more wisely, in order to secure its many vital services for future generations. The EU faces new territorial challenges.

  • A phenomenon in the unplanned urban sprawl of Cheong-ju city has to be rest-rained from disposing and to develop, though progress in urbanization inevitably decreases rural area. So, this thesis aims at reviewing, revising and guiding toward the more effective land use planning practice and zoning mechanism and system of Cheong-ju city. I proposed that land use planning should be had several factors and thereupon that Korean zoning mechanism and system including Building Code should be amended because of inducing human activities in buildings and facilities not to demarcate and plan every one of them. First, the factors of urban planning are a rather diversified approach to it than a unified, supplementation of the applicable difference in time between preparing and appling it, a solid controlling system, a micro and macro planning theory and giving serious consideration for the inertia from the existing land use. Second, the applicable amendments for our zoning mechanism including Eluding Code are as follows; a need of reorganization for Zoning Ordinance appricated to different regulation concerning a scale and peculiarity of a oily, a decision of the different earmarked confinement in area to different zone ana from Zoning Ordinance in City Planning Law, a demarcated facilities and the more detailed land use concerning human activies than the exsisting and entrusting decision on the ways and processes of it to every rural city planning committee, a settlement of zone ana area considering for block-unit and Planned Unit Development(P. U. D.), and a need of security jurisprudence in order to solve the zoning regulation rather in City Planning Law than in Building Code that our zoning regulation and controlling system are depended on. According to these applicable amendments to Cheong-ju city, I proposed the conceptions of Cheong-ju city land use planning are as follows; a reinforcement with one cored pattern of urban land use, a selection of gradual urban sprawl by way of city development and renewal, a strengthening accessibility to the core of the city with Plurizing the system of arterial roads, a choice of priority to conservation at the core of tile city and security of open spaces and parking area at the area of the city, a harmonization between development and conservation at the inner ring area that is situated between the core and periphery reserved area in order to develop in the future, a buffered open space situated at the congested area with heterogenous functions, and a completion of urban open space system. The proposal made here so far is for the hope of the better structure of Cheong-ju city that should be granted to the peculiarity developed with educational, cultural, conservative and self-sufficient city functions.

  • The old city centers of local metropolitans have lost their functions as CBD in korea. Those old city centers have an only role as a gate connected to the new CBD. This study aims to present regeneration stratigies of old city centers through Osaka case study. This research has been focused on the physical and environmental factors in urban regeneration. There are 4 strategies for old city centers. First, the strategy to attract people to the old city centers is high-density and mixed-use development having functions like shopping, entertainment, residence. This kind of development makes local metropolitan cities compact cities to protect urban sprawl. Second, strategy to give old city centers an identity is to conserve traditional culture and structures and to revitalize retail market. Third is to make pedestrian-friendly street system. Osaka ism't pedestrian friendly but remodelling the connect the pedestrian path to the culture facilities. Fourth is to have water and green environment. Green space is the strong factor that pull people to old city centers.

  • The uncontrolled urban expansion causes various social, economic problems and natural/environmental problems. Therefore, it is necessary to forecast urban expansion by identifying various factors related to urban expansion. This study aims to forecast it using a decision tree that is widely used in various areas. The study used geographic data such as the area of use, geographical data like elevation and slope, the environmental conservation value assessment map, and population density data for 2006 and 2018. It extracted the new urban expansion areas by comparing the residential, industrial, and commercial zones of the zoning in 2006 and 2018 and derived a decision tree using the 2006 data as independent variables. It is intended to forecast urban expansion in 2030 by applying the data for 2018 to the derived decision tree. The analysis result confirmed that the distance from the green area, the elevation, the grade of the environmental conservation value assessment map, and the distance from the industrial area were important factors in forecasting the urban area expansion. The AUC of 0.95051 showed excellent explanatory power in the ROC analysis performed to verify the accuracy. However, the forecast of the urban area expansion for 2018 using the decision tree was 15,459.98㎢, which was significantly different from the actual urban area of 4,144.93㎢ for 2018. Since many regions use decision tree to forecast urban expansion, they can be useful for identifying which factors affect urban expansion, although they are not suitable for forecasting the expansion of urban region in detail. Identifying such important factors for urban expansion is expected to provide information that can be used in future land, urban, and environmental planning.

  • 전 세계적인 저성장 기조로 인하여 주요 선진국에서는 도시축소문제가 도시정책의 주요 이슈로 대두되고 있다. 국토연구원의 연구결과(2016)에 따르면 우리나라 77개 도시 중 23개 도시가 지속적 또는 일시적 축소도시로 진단되었다. 그러나 축소도시를 진단하는 기준은 단순한 인구통계학적인 측면에 머물러 있으며, 도시의 공간적 축소패턴은 고려되지 않고 있다. 따라서, 본 연구에서는 도시공간구조 분석방법의 하나인 인구밀도경사함수를 이용하여 다핵도시인 영주시의 특성을 고려한 도시축소현상을 진단하였다. 진단결과, 영주시는 CBD의 인구밀도 및 인구밀도경사도가 증가하는 축소도시의 특성을 보이고 있다. 동지역의 경우 CBD의 인구밀도 및 인구밀도경사도가 감소하는 스프롤(sprawl) 현상이 나타났다. 또한, 풍기읍의 경우 CBD의 인구밀도만 감소하는 단순축소 현상이 나타났다. 본 연구결과는 한 도시 내에서도 중심지마다 공간변화의 패턴이 상이하게 나타날 수 있다는 것을 보여주었으며, 다핵구조를 갖는 도시의 경우에는 도시 전체뿐만 아니라 세부 지역에 대한 개별적인 진단이 필요하다는 시사점을 도출하였다.

  • Since 1990, urban areas have been expanded rapidly due to the concentration of the population and several development projects including large scale apartment complexes and residential developments. Due to these development projects, the quality and functions of ecosystems have been continuously degraded, regardless of public agencies' efforts introducing development index, guideline, and amendment of law for sustaining the quality of ecosystems. Substantial guideline and content cannot expect the sustainable maintenance of nation's natural resources. Recent improve this situation, ecological planning was introduced, but research data of environments and objective systems were not enough showing the limits. The purposes of this study were to reduce the urban sprawl caused by residential development plans for environment-friendly residential developments, to establish applicable ecological planning, and to suggest the land use plans that reduce adverse effects of developments to nature ecosystem.
