  • This paper aims to interpret the transformation process of town plan of Gosan-up(高山), which was provincial administrative focus town in Josun dynasty, basing on morphological viewpoint. Morphological concepts, such as morphological frame, urban plan, kernel, colonization, route system, fixation line, fringe belt, plan unit & plan division, morphological period derived from the study of Conzen, M.R.G. and Caniggia, G. epidome district, break point, broken plot, urban fallow, privatization are adopted for the interpretation of urban form. Morphological period of Gosan can be divided in four ; formation of kernel & morphological structure, disintegration & redevelopment of the kernel, augmentative development of the kernel & formation of modern epidome district, outwards expanding of urbanized area, transition & reorganization of epidome district. Especially public leading projects such as construction of new regional connection road and public facilities such as myeon(township) office, agricultural cooperatives federation office, market, are main factors of morphological transformation of townplan. In the early stage, under the Japanese imperialism, construction of the new matrix route(Gosan-ro) through the kernel and followed planned routes gave way to disintegrating traditional areal plan unit and forming small block plan units in administrative facilities area. And linear plan units with commercial buildings were formed along the new matrix route and planned route adjacent to periodical market. In the latter stage, with development of public facilities, private sectors' large circulation institution and terminal outside the kernel with planned routes formed areal block based plan units with commercial and public buildings. And part of the spatial area with the linear plan unit were turned into urban fallow. With the transformation of town plan, new roads outside the kernel have substituted for traditional fixation line of waterway with road and topographical feature. Fringe belts were made successively along the new road and around the major intersections outside of existing urbanized area. Land use in fringe belts, constituting of outer locational tendency early on formation, was gradually replaced with commercial & business buildings.

  • Greenhouses gas emission due to usage of fossil fuel has been known as one of the main causes of global warming. Fundamentally, greenhouse gas is a by-product of economic activity. Since majority of economic activity happens in an urban setting, a countermeasure in an urban setting is needed. Therefore, an analysis of relationship between carbon dioxide emission and urban form will be investigated for urban planning and management in the future. The purpose of this study is to analyze the relationship between carbon dioxide emission and urban spatial patterns, and suggesting an urban form with low carbon dioxide emission. In order to achieve this, first theoretical analysis was carried out on urban spatial patterns related to physical size, usage rate, and activity level. Secondly, Seoul's dam on electricity, natural gas, local heating, petroleum, and water usage and mapping a carbon dioxide emission map. Thirdly, relationship between carbon dioxide emission and urban spatial patterns are analyzed and urban spatial patterns that affects energy usage in urban setting was elucidated, and elicited implications on future directions on urban planning based on our analyses above.

  • The purpose of this paper is to conduct an experimental measurement and analysis of cities' morphology. Fractal theory that is an effective tool for evaluating self-similarity and complexity of objects was applied. For the comparative analysis of fractailities and computational verification, two totally different cities in Japan were selected. They are Kitakyushu City, which is a big and fully developed city, and Jinguu Machi of which almost all the area is covered with agricultural land use. After converting vector data to raster data within GIS, fractal dimensions of two cases in Kitakyushu City and one case in Jinguu Machi were calculated. The calculation showed that two parts of Kitakyushu City were already fractal. Jinguu Machi, however, was difficult to find fractality. As a conclusion, fractal was proved to be an useful tool to estimate the shape of cities reflecting their internal spatial structure, that is self-similarity and complexity.

  • 지난 수십 년 동안 형태지수는 패치의 복잡성을 정량화하여 생물종 다양성 보존과 같은 경관생태계획에 활용되어 왔다. 지역계획 연구자들이나 정책결정자들에게 경관구조와 패턴을 정량화하는 경관생태지수는 대상지역을 모니터링할 수 있는 하나의 수단으로 활용되어 왔다. 그러나 경관생태지수관련 연구를 살펴보면 연구 목적 및 범위에 따라 활용하는 경관생태지수의 종류가 매우 다양하고 복잡한 것을 알 수 있다. 또한 연구목적에 적합한 경관생태지수를 선정하는 것은 복잡한 수학분석과 함께 많은 주의가 필요한 것을 알 수 있다. 따라서 본 연구에서는 형태지수들을 도시지역, 도시외곽지역, 농촌지역 그리고 산림지역 등 4군데 사례지역에 적용하여 그 결과를 통해 형태지수들의 특성을 살펴보았다. 그 결과, 평균형태지수값(MSI)에서는 도시외곽지역이 가장 높게 나타났고, 평균프랙텔차원지수(MPFD)에서는 농촌지역이 높게 나타났다. 넓은 면적을 가진 패치에 가중점을 고려한 평균형태지수값(AWMSI)과 평균프랙텔차원지수값(AWMPFD)에서는 산림지역이 가장 높게 나타났다. 사용한 네 가지 형태지수값의 순위가 4군데 사례지역에서 다르게 나타났다. 특히 둘레와 면적의 로그전환을 이용하고 있는 프랙텔차원지수들의 경우, 도시와 도시외곽지역의 MPFD값은 같고, 도시외곽지역, 농촌지역과 산림지역의 AWMPFD값 차이는 적어 순위 분별력이 떨어졌다. 따라서 넓은 면적을 가진 패치에 가중점을 고려한 평균형태지수(AWMSI)가 지역별 산림패치의 복잡성을 잘 정량화할 수 있음을 본 연구결과에서 보여주고 있다.

  • The final purpose of this study is to explore morphological change of Shenyang in the period of the rising Chung Dynasty. For that purpose we have tried to build the historical GIS DB of site and analysis of the structure and shape pattern of the city by using the functions of GIS. From the view of spatial structure and cultural context, main characteristics, which is derived from the analysis of ancient map of Shenyang, can be summarized into five things as follows ; transformation of open spatial structure into closed structure, combination of horizontal spatial structure with vertical structure, transformation of practical spatial structure into symbolic structure, transformation of natural spatial structure into institutional form of ancient Chinese capital city, conservation of traditional Manchurian culture.

  • This study aims to draw a correlation in the choice of automobiles as the preferred mode of personal transport in relation to three factors: 5Ds, urban form and individual-level characteristics. The analysis result shows that the control at the individual level is required to analyze effective urban character and urban form elements to decrease the car choice and the 5Ds demonstrate meaningful relation to decreasing the car choice. However, it may be concluded that the density and the diversity, well-known elements in decreasing the car choice among Western cities do not show relatively large impact on Korean cities.

  • 서울은 인구 1000만이 넘는 세계적인 대도시로 발전하였다. 1970년대 이후로 급속적인 경제발전과 더불어 서울의 도시화는 급속히 이루어졌으며 이에 따른 인구집중 역시 빠른 속도로 진행되었다. 본 연구에서는 서울과 그 주변 도시를 대상으로 인구자료와 행정구역도 그리고 Landsat 위성영상을 사용하여 인구밀도의 변화에 따른 도시의 성장형태를 분석하여 도시의 관리와 발전계획을 위한 기초 자료로 활용하고자 한다. 도시성장 분석을 위한 기존의 연구방법은 행정구역에 따른 인구밀도를 통해 수행되었으나 이는 행정구역 내에 일률적인 인구데이터의 분배로 실제 경우와 다른 해석이 가능할 수 있는 오류를 포함하고 있다. 이에 본 연구에서는 실질적인 대부분의 인구가 도시지역에 거주한다는 가정 하에 1985년부터 2000년까지의 5년 간격의 Landsat 위성영상을 사용하여 도시지역을 추출하고 이를 기초로 행정구역 내에 포함되어 있는 도시지역에만 인구를 배분하는 새로운 방식으로 인구밀도의 변화 추이를 나타내었다. 연구결과 기존에 방법에서는 발견되지 않았던 서울의 확장형태를 알 수 있었으며 또한 인구데이터의 경계현상을 Pycnophylactic 보간 알고리즘을 통해 제거함으로써 보다 실질적인 도시지역 인구밀도의 변화를 알 수 있었다. 이러한 인구밀도의 변화는 도시의 성장과 밀접한 상관관계를 갖기 때문에 이를 통해 서울 및 주변도시의 성장 형태를 확인할 수 있었다. 마지막으로 4장의 서울-경기 도시지역의 인구밀도 변화도를 제작하여 GIS를 이용한 관련 분야의 활용에 도움이 되고자 한다.

  • 도시공간은 도시민의 안정적인 경제/문화/기타 활동 유지를 위해 개발 및 관리되어진다. 최근 도시공간 내에 존재하는 다양한 형태의 구조물에 대한 안전에 많은 관심이 쏠리고 있는 상황에서 이러한 도시 구조물에 대한 신속 정확한 형태학적 특성 분석이 요구되고 있다. 그러나 이러한 도시 구조물에 대한 모니터링에 대한 관심에 못지 않게 주변의 다양한 식생이나 피복에 대한 분석에 대한 요구가 증가하고 있다. 따라서 이 연구에서는 도시공간내 존재하는 다양한 식생의 피복을 분석하기 위해 NIR 방사 자료를 활용하는 기초적 연구를 통해 근적외선 방사자료를 통한 피복분석을 효과적으로 실시하였다.

  • This study analyzed the situation of urban agriculture development through theories, paradigms, and typology to determine the application frequency and development keywords about space forming. The results showed that urban space by distance determines "Dimension of space forming" through self-production, public-production, and nation-social operation. Second, the complex space by shape determine "Identity of space forming" through "Flat Shape" for using the widespread land, "Compact Shape" for overcoming the small and poor land, and "Fusion of Flat Compact Shape" for systematic use between Flat and Compact. Third, building and interior space according to location determine the "Utility of space forming" through land, roof, wall, veranda, interior, and infrastructure space. The concepts about space forming of urban agriculture have an organic correlation and will be developed sustainably by the evolved cases from now on. In addition, space forming of urban agriculture produces new creation space by various fusion processes and will be a development trend of new urban agriculture.
