The purpose of this study was to analyze legal characteristics and issues of an underground pedestrian connection, which is a very useful tool to create 3D pedestrian networks and the vibrant underground environment. To do this, this paper explored the related laws to install the connection and analyzes 74 cases of Jung-gu, Seoul to find major issues. Then, it defined the legal characteristics in terms of not only the laws but also property law in Korea, thereby suggesting the improvement schemes. As a result, this paper concluded that the connections can be installed by an Urban Planning Facility or a Road Occupation Permit, but should be considered their public interest. In addition, exactions or fees for the permit should be carefully implemented based on the characters of the connection.

본 연구에서는 열환경 취약성 평가에 관한 국 내외 선행연구 고찰을 바탕으로 열환경 취약성 평가에 적합하면서 도시 및 환경계획 등 공간계획 분야에서 활용할 수 있는 취약성 평가지표를 선정하고, 이를 활용하여 사례지역인 서울시의 열환경 상태를 진단하였다. 이를 위해 폭염, 도시 열섬, 도시 미기후 등 국내 외 열환경 취약성 평가에 활용된 지표들을 고찰하여 도시 열환경 취약성 평가를 위한 15개 지표를 선정하였는데, 기후노출 분야의 건물체적, 민감도 분야의 열환경 취약 건축물, 적응능력 분야의 녹지면적 등 도시구조적 공간적 지표를 포함하였다. 선정된 지표 중 사례지역인 서울지역에 대해 활용가능한 12개 지표의 공간정보를 구축하고, 퍼지이론을 활용한 GIS 공간분석을 통해 서울의 열환경 취약성을 평가하였다. 분석 결과, 강남 지역이 강북 지역보다 열환경에 더 취약한 것으로 파악되었는데, 강남 지역에서는 서초구, 강남구, 동작구, 영등포구, 강서구 일대의 열환경 취약성이 상대적으로 높게 나타났으며, 강북 지역에서는 동대문구, 강북구, 광진구, 중랑구 일대가 다른 구에 비해서 취약성이 높은 것으로 나타났다. 산림지역 및 서울시 외곽지역에 위치한 관악구, 도봉구, 은평구, 노원구 등은 관악산, 북한산 등 산림의 영향으로 인해 '기후노출'과 '민감도' 분야의 취약성이 낮았다. 하지만, 자료수집의 한계로 활용하지 않았던 '적응능력' 분야의 에어컨 보유 현황 지표가 분석에 반영된다면, 서초구, 강남구 등 취약성이 높게 평가된 지역의 결과에 영향을 미쳤을 것으로 예상된다. 본 연구는 기존의 국내 열환경 취약성 평가에서 활용하지 않았던 도시구조적 공간적 지표를 활용함으로써 도시 및 환경계획 분야에서 열취약성을 개선하기 위한 정책 마련에 기여하고, 열환경 위험성을 저감하기 위한 공간계획 수립에 기여할 수 있을 것으로 판단한다.

수도권의 인구밀집 현상은 우리나라의 큰 사회문제이다. 이러한 문제를 해결하기 위해 신도시를 건립하여 인구를 분산시키려 노력하고 있지만 서울과의 접근성이 극심한 교통체증으로 인하여 약하기 때문에 신도시들은 베드타운의 역할을 잘 수행하지 못하는 실정이다. 이러한 문제는 대중교통수단의 확충이 그 해결책이 될 것이다. 따라서 국내 수도권 도시철도망의 경우 향후 연장길이 확충은 물론 경량전철 둥 다양한 유형의 도시철도가 도입될 예정이다. 이러한 계획을 성공적으로 수행하기 위해서는 철도자체의 특성에 대한 고려뿐만 아니라 도시철도가 건설되는 지역의 종합적인 검토가 필요하다. 본 연구에서는 지리정보시스템의 공간분석기능을 이용한 의사결정 지원시스템을 설계함으로서 기존 도시철도 건설계획 수립과정을 개선해보고자 한다.

This study focuses on hydrological changes caused by developments in the 13th, 14th (Motjarigol) district in Eun Pyoung New Town, Seoul on the basis of the Land Use Planning of development plan. Through analyses from the hydrological experiments about rainfall outflow using universal equation and amounts of infiltration through soils, the changes in amounts of overflows were estimated and the results were discussed from a urban ecological point of view. As a result, it has been predicted that the amount of rainfall outflow at post-development was dramatically increased, compared to pre-development. Installing of Derbris Dams and infiltration facilities were suggested as alternative plan to meditigate these changes. If we apply these alternatives, the rainfall outflow would be reduced up to 30% compared to the development plan without BMPs (Best Management Practice). In conclusion, it is proposed that once the ecological principles were considered during development planning process, we can minimize the adverse effects of developments to our environments.

This study aims to develop the Extended Urban Land Information System (EULIS) which can support the sustainable urban management. Although the existing Urban Land Use Information system (ULUIS) that aids the micro-level land use information is a good means for the understanding of urban spatial structure and district-level planning and management (such as urban design, redevelopment planning and district-level transportation planning, etc.), it has some limitations in supplying the information for sustainable urban management, such as environmental and traffic analysis, urban infrastructure's carrying capacity analysis, etc. The EULIS is designed to efficiently supply the information for sustainable urban management. For the successful construction of EULIS, the followings have to be considered. 1) the integration of topographic maps which contain the building's footprints and cadastral maps which contain the parcel's boundary, 2) the integration of EULIS and FM (Facility Management) system for the full utilization of information about capacity analysis of infrastructure, 3) the construction of standardized georeferencing system and spatial unit for the combined use of environment and traffic census data. This study shows 1) why EULIS is needed for the sustainable urban management and which elements are needed for the system,2) the E-R data model for the EULIS, 3) the strategies for the construction of EULIS and 4) the conclusion.

도시 계획적 측면에서 도시의 구조적 변화에 따른 기후영향을 파악하여 그 결과를 도시계획에 반영하는 것은 중요하다. 서울시에서는 도시계획 시나리오 정보를 제공하기 위해 도시계획정보시스템(Urban Plan Information System, UPIS)을 활용 중이다. 지자체의 실제 도시계획에 따른 기후영향을 평가하고 분석하기 위해서는 UPIS에서 제공하는 도시계획시나리오와 도시기후분석모델을 손쉽게 연계할 수 있어야 한다. 본 연구에서는 국립기상과학원의 도시기후분석모델(Climate Analysis Seoul, CAS)과 도시계획 시나리오를 연계하는 기술을 개발하였다. CAS는 건물과 식생의 물리적 배치에 따른 온도, 바람 등의 국지규모 변화와 중규모 기상모델인 MetPhoMod(METeorology and atmospheric PHOtochemistry mesoscale MODel)의 분석결과를 바탕으로 찬공기의 생성, 이동, 정체와 바람흐름, 열적환경 등을 분석하는 기능을 가지고 있다. 정밀한 도시정보를 모델에 적용하기 위해 고해상도의 항공 LiDAR(LIgit Detection And Ranging) 측량을 통해 생성된 래스터자료(1m 해상도)와 KOMPSAT-2(KOrea Multi-Purpose SATellite) 위성영상 자료(4m 해상도)를 이용하여 토지피복 및 수치표고자료로 활용할 입력자료를 생성하였다. 보다 정확한 도시지면 특징을 반영하기 위해 수치표면모델인 DSM(Digital Surface Model)과 수치지형모델인 DTM(Digital Terrain Model)을 전산유체역학모델(Computational Fluid Dynamics, CFD) 입력자료로 사용하여 상세바람분석을 수행하였다. 8방위의 유입류를 고려하여 재정비 전후의 도시구조물 주변의 흐름 및 풍속 분포와 녹지축 형성 전후의 열환경 변화를 분석하였다. 현실적인 기상상태 반영을 위해 CAS의 중규모 기상장을 입력자료로 사용하였으며, 그 결과 재정비에 따른 도시구조물 변화에 의해 바람길에 큰 변화가 확인되었다. 녹지축 형성 이후 전반적으로 재정비지역 주변의 온도가 감소하였다. CAS와 CFD의 연동을 통해 도시지역 재정비와 녹지축 형성 전후의 주변 바람길과 열환경에 대한 실제적인 평가가 가능하며, 도시개발계획과 녹지조성계획 수립에 유용할 것으로 기대된다.

The purpose of this study was to carry out land use suitability analysis of Seoul Metropolitan City based on ecopolis planning concept or environmentally sound and sustainable development. Objectives of the analyses were to save energy by increasing urban density and allocating urban land use types near to public transportation system, to increase food producing capacity by restoring fertile agricultural lands, and to enhance urban ecosystem by expanding and networking parks and green spaces. This study has two phases. First, the land use suitability analyses for commercial, industrial, residential, agricultural, and green spaces were carried out. Second, required urban land use .types were allocated based on ESSD concept. Two alternative land use plans were developed based on two population sizes:existing population of 11million and 4.4million derived by the application of ermergy theory of T. Odum.

The purpose of this study was to propose an ecological management plan by the comprehensive analysis of biotope structures on Namsan Urban Natural Park in Seoul. Classified by actual vegetation, structure of layer and vegetation damage, biotope structures were composed of forest area, compact management area, herb area, cultivated area and non-ecology(urban) area. Succession had seened to stop in the Native forest. Artifical forest was divided into two types. The first, upper layer, was too dense to accommodate lower layer plants, the other case was the appearance of Quercus spp. and the first stage plants of succession following the declination of the upper layer plants. The soil pH of Nam-san Urban Park was 4.21∼4.51, which meant the soil was becoming acid. As the result of acidity, leaching of available nutrition(K/sup +/, NH₄/sup +/, Ca/sup ++/ etc.) was immediately influenced by the natural ecosystem, influence of acid rain was disturbed to becoming organic matter which was use to plants. In the case of a biotope structure management plan, the urban area was prohibited to spread outside. Cultivated and herb area was regenerated to natural forest. In the forest area, the compact management area was maintained with its present condition, and then it is desirable to make a preservation area and to plant shrubs. Planted Pinus densiflora Community was needed to eliminate competitive species of canopy layer, and plant shrubs. Management of deciduous broad-leaved Comm. was maintained in its present conditionand it is desirable to raise the diversity of the understory and shrub layer. The management of the artifical forest seems to be suitable for Q. spp. community. The care of naturalized plants prevents the expansion and restores the structure of wild plants. The soil management was a marked restoration soil ecosystem in order to prevent soil acid and drying.

It is certain that urbanization has transformed the ecological consequences severely, but urban ecosystem is not fully understood yet. Urban growth is not like a static form and it spreads spatially and temporally. Therefore in studying urban ecosystem, it is important to relate the spatial pattern of urbanization to ecological processes. Using gradient analysis, we attempted to quantify the urbanization's spatial impacts in Daejeon-city and Cheonan-city, Chungcheong-province, Korea. Because of Multifunctional Administrative City Planning (MACP), a lot of development projects are planned in Chungcheong-province, Korea. It's important to study about original cities' patterns and impacts. These results can be adopted to future city planning. So several measures such as fragmentation, vegetation index, surface temperature, population density, and income rate were computed along a 75km long and 3km wide transect. The results showed that Daejeon-city has a wider urban center, lower vegetation indexes, and higher surface temperature than Cheonan-city. Therefore in the perspective of urban environments and sustainable urbanism, it seems that Cheonan-city is better than Daejeon-city. The changes along the transect have important ecological implications, and quantifying the urbanization gradient is an important step in understanding urban ecology.
