The environmental conservation-targeted zoning in urban planning process has been functioned as securing a ecological core in urban green spaces management. Hence, the designation of conservation zones in land use planning is considered as a key task to achieve the sustainability of urban planning. The recently introduced pre-environmental review system for the proposed urban plan, by which the conservative measures for urban ecosystem and landscape are suggested in aspect of environmental impact mitigation, has played an active role in enhancing the environmental performance degraded by wide range of development pressure. This study is aimed at drawing out of objective criteria for designation of environmental conservation zones, which can be applied to urban planning establishment and also to environmental assessment process. To achieve this goal, the study adopted the following methods; pre-study review, analysis of existing official opinion statements released by the Ministry of Environment, contents analysis of related laws, and experts' panel discussions on the finally arranged criteria. The results of this research can be summarized as follows: First, the total criteria of 48 are drown out with categorizing into environment-ecological and socio-cultural sectosr. Second, the environment-ecological part is composed of 33 criteria such as vegetation, animal, geomorphology, watershed, environmental land suitability, and etc. Here, the Degree of Ecological Function, Degree of Environmental Land Suitability, and Vegetation Map are mainly utilized. Third, the 15 socio-cultural criteria relating to the history, social ecology and landscape have such components as forest around relics, Seo-won(school), castle, tomb, landmark, skyline, natural landscape, and etc. Forth, these individual criteria can be applied to designation of each conservation zones among total of 11 conservation areas(or districts).

The landslide disaster damage has been increased by mountain development, leading to construction of educational facilities, medical facilities, petty industrial facilities, and large housing complexes. Therefore, effective regulation is required as an effort in urban planning solutions. For suggesting specific mitigation strategies on urban landslide, this study aims to define evaluation criteria for urban planning management of debris-flow disaster. AHP (Analytic Hierarchy Process), one of the multiple criterion decision making methods, was utilized in this study. This study makes use of 16 sub-criteria under the framework of hazard, exposure, and vulnerability, and well-planned expert survey measures their weights. The weights are also applied to evaluate each grid in urban space (min $10{\times}10m$) and classify it with red, orange, yellow, or green grade so that areas at higher risk are clearly identified. This study concludes that the suggested method is useful to support a strategies for urban planning management of debris-flow disaster, particularly in a GIS base.

Studies on landscape ecology have focused on conceptual aspects, while empirical focus for spatial planning has been rarely conducted. This study conducted an empirical analysis to enhance landscape ecological performance of urban developments using landscape ecology. To do so, concrete criteria and standards to analyze structural, functional and variational mechanisms of urban landscape ecology were developed. An integrated landscape ecology assessment model that can be applied to urban development planning was established by combining the criteria. Next, Landscape Ecological Management System (LEMS) was developed to implement an integrated assessment using GIS. To verify the effectiveness of the system, a case study was conducted using LEMS on Byulnae City in the Seoul Metropolitan Area. The LEMS can be useful for urban planners and policy makers in their selection of desirable planning alternatives. Moreover, the LEMS developed in this study can be a useful tool for academia in terms of the implementation of further related studies, and for planning professionals in their environmental impact assessment tasks.

This study aims to develop a potential evaluation method for urban spatial expansion using remote sensing (RS) and geographic information system (GIS). A multi-criteria evaluation method with several criteria and their weighting values was introduced to evaluate the score and quantification of the potential surface around the existing cities. The six criteria with one geographic factor, slope, and five accessibility factors, time distance from center of the city, national road, interchange of expressway, a big city, and station, were defined for the potential. RS techniques were applied for classification of the actual urban expansion maps between two periods, and GIS functions were used for score of accessibility criteria with a distance decay function from geographic, road and several point maps, which was developed in this study. The new methodology was applied to a test area, Suwon, between 1986 and 1996. In order to optimize the six weighting values, this study made new findings to search the optimal combination of the weighting values from new methodology, weighted scenario method for intensity order (WSM), combined with intensity order and AHP method, including a trial and error method for sensitivity analysis to make the intensity order. The optimal combination of the weighting values by the new method generated the optimal potential surface, considering spatial trend of urban expansion in the test area.

A spatial simulation model for rural and urban sprawl phenomena was developed with GIS and cellular automata techniques. The model finds out built-up areas invading toward rural areas required for development of existing urban area. Probability of land use change for optimizing the development area was determined using a land suitability analysis method interfaced with GIS methods, based on several criteria in terms of geographic and accessibility factors such as slope of land and distance from city center. Weighting values of the criteria were quantified by an analytic hierarchy process method. For model applicability test, the parameters of criteria were calibrated based on the changes in time series land use data of the test city for 1986, 1996, and 2000, which were classified by remote sensing techniques. Simulated and observed areas in land use maps for city shape of 1996 showed good similarities with each other through a morphology verification method. The model enabled us to evaluate the spatial expansion phenomena of cities considering boundary conditions, and also to simulate land use planning for rural areas in urban fringe.

The purpose of this study is to propose the rural landscape planning criteria for Korean rural area. For this, the meaning of rural landscape is defined, and the legislative framework and several legal processes are surveyed, including the deliberation system for natural landscape impacts and the Landscape Law recently legislated. Through literature studies and analysis, the rural landscape planning criteria are proposed, which have step-by-step processes; goals and objectives, analysis and estimation for present conditions, basic planning concept, landscape planning for different visual landscape types, landscape designing for visual elements, and practical action plans. Each processes are designed considering the existing legislative framework, so it can be well-matched to current systems. But, because there are few rural landscape plans so far, comparing to the urban landscape plans, the validity of this criteria should be verified in the future studies.

The purpose or this study is to simulate spatially the urban expansion phenomena with a cellular automata (CA) technique using GIS. A study area, Suwon city, was selected for test of model verification and application with the classified land-use maps of three data years: 1986, 1996, and 2000. The urbanized potential maps were generated with seven criteria of one geographic factor (slope of land), and six accessibility factors (time distances from city, national road, Seoul, station, and built-up boundary), considering their weighting values, which were optimized by WSM (weighted scenario method for intensity order) combined a ranking method and a AHP technique. The optimized weighting values at the urban expansion between 1986 and 1996 were applied to verify the CA model for the other expansion between 1996 and 2000. The results of model application showed that urban sprawl phenomena of the urban expansion toward rural area can be simulated spatially and temporally with several boundary conditions considering various scenarios for the criteria and parameters of the model. Ultimately, this study can contribute to reference data for land-use planning of urban fringe areas.

This study aims to analyze the sensitivity of WSM(weighted scenario method)-AHP method according to variation of nonlinear exponent for accessibility criteria, which are used to make urbanization potential maps with the optimal weighting value for multiple criteria in grid-based GIS technique. Besides this study tried to develop WSM-AHP2 which is simplified by using rank of the potential value for each scenario. The two methods were applied to the test area, Suwon city located south area of Seoul, with time series land-use maps of 1986 and 1996. The evaluation system of urbanization potential have 7 criteria including 6 accessibility criteria. The results of WSM-AHP2, the optimal weighting values and their corresponding potential maps, have almost similar with those of WSM-AHP. In the application of CA(cellular automata) model for expansion of urbanized area using the three potential maps by WSM-AHP, WSM-AHP2, and specialists's AHP evaluation, it also showed that the accuracy of simulation for actual urban area is the highest in the potential map of WSM-AHP, followed by WSM-AHP2 and specialists's AHP evaluation. From the results of this study, WSM-AHP and simplified WSM-AHP2 will be used to generate the optimal potential maps for land-use planning in urban fringe area.

도시공간은 온실가스배출의 주원인지로 온실가스 저감을 위해서는 도시적 차원의 대책이 무엇보다 필요하다. 본 연구는 도시공간을 조성하는데 있어서 활용할 수 있는 이산화탄소 배출량 산정 모델을 개발하는 것을 목표로 하고 있다. 이를 위해, 첫째로 물리적 규모, 이용현황, 활동강도와 관련된 도시공간 계획요소를 이론고찰을 통해 선정하였다. 둘째, 전력, 도시가스, 지역난방, 석유, 상수도 사용량 자료에 기반한 이산화탄소 배출량을 산정하였다. 셋째, 서울시를 사례연구대상지로 선정하고 도시공간 계획요소와 이산화탄소 배출량 간의 관계분석을 통해 도시공간의 이산화탄소 배출량 산정 모델을 개발하였다. 기후변화에 대응하기 위한 다양한 노력들이 도시공간에서 시도되고 있으나, 도시 전체의 탄소배출량과 같은 총량적 관점의 한계가 있었다. 그러나 본 연구의 도시공간 계획요소에 따른 이산화탄소 배출량 산정 모델은 탄소저감을 위한 도시차원에서의 해결방안으로 활용할 수 있는 국지적 범위에서의 보다 구체적인 모델을 제시할 수 있다는 점에서 기존 연구와의 차별된다.

본 연구의 목적은 도시경관계획의 효율적 실행수단 확보 차원에서 도시경관 유형화를 위한 기초자료를 구축하는데 있다. 이를 위해 국내 주요 학술지 논문과 경관계획 보고서 중 경관유형과 분류기준을 구체적으로 제시한 기존 연구를 분석하고, 이를 토대로 현행 도시계획의 근간이 되는 용도지역지구제에서 활용 가능한 도시경관 유형화 분류기준을 제시하였다. 연구결과는 다음과 같다. 첫째, 분석과 평가 관점의 경관유형화 방식은 생태학적 접근과 형식미학적 접근에 기반하여 경관요소들의 특성을 분석하며 이를 토대로 경관을 유형화하는 것이 큰 특징이라고 할 수 있다. 둘째, 우리나라 경관계획에서 보여지는 경관유형은 분석을 위한 경관유형과 계획을 위한 경관유형의 혼용에 의해 논리적인 경관유형 분류체계가 확립되지 않았으며, 이로 인해 경관관리대상에 대한 명확한 규정이 없다는 것이다. 이는 결국 경관관리를 위한 경관제어요소와 관리방안에 대한 구체적인 지침 부족으로 연결되고 있다. 본 연구에서는 경관계획 과정상의 효용성을 고려하여 활용 가능한 경관유형 분류기준을 크게 경관구성의 1차적 기준과 2차적 기준으로 제시하였다. 1차적 기준은 지형과 용도지역지구, 경관자원의 성격, 경관요소가 있고 2차적 기준은 경관계획 대상지 외부에서 경관을 구성하는 조망점, 조망점과 경관대상과의 거리, 도시공간의 형태적 특성 등으로 구분할 수 있다. 이를 이용한 도시경관 유형화는 도시 전반에 대한 경관관리가 가능하게 할 것이며, 향후 도시경관유형을 토대로 한 용도지역지구의 운용에 있어 기초자료로 활용될 수 있으리라 판단된다.
