  • The purposes of this study are to apply species distribution modeling in urban management planning for habitat conservation in non-urban area and to provide a detailed classification method for management zone. To achieve these objectives, Species Distribution Model was used to generate species richness and then to compare with the results from land suitability assessment. 59 species distribution models were developed by Maxent. This study used 15 model variables (5 topographical variables, 4 vegetation variables, and 6 distance variables) for Maxent models. Then species richness was created by sum of predicted species distributions. Land suitability assessment was conducted with criteria from type I of "Guidelines for land suitability assessment". After acquiring evaluation values from species richness and land suitability assessment, the results from these two models were compared according to the five grades of classification. The areas with the identical grade in Species richness and land suitability assessment are categorized and then compared each other. The comparison results are Grade1 10.92%, Grade2 37.10%, Grade3 34.56%, Grade4 20.89% and Grade5 1.73%. Grade1 and Grade5 showed the lowest agreement rate. Namely, development or conservation grade showed high disagreement between two assessment system. Therefore, the areas located between urban, agriculture, forest, and reserve have a tendency to change easily by development plans. Even though management areas are not the core area of reserve, it is important to provide a venue for species habitat and eco-corridor to protect and improve biodiversity in terms of landscape ecology. Consequently, adoption of species richness in three levels of management area classification such as conservation, production, planning should be considered in urban management plan.

  • Land suitability assessment(LSA) is a useful method to assess land characteristics according to its physical, locational, and environmental characteristics, and then to classify it into several categories based on its usability and the necessity for conservation. Therefore, the credibility of this assessment result depends on the rationality of assessment method such as computation of suitability values and the criteria of ranking the land grade. This study focused on identifying problems in current LSA method by critically reviewing it, and aimed to suggest a suitable method for the assessment of land suitability. As a alternative method in this study, linear transformation method was used for scoring factors instead of critical values and the weight for each assessment factor. and all values of those factors were added to produce comprehensive suitability values. Those values were ordered and categorizied with suitability level based on the ratio of square measure. After comparing existing LSA method to the suggested alternative method, it is concluded that the alternative method was more suitable to assess the characteristics of lands than existing LSA method. This method was also suitable to represent the characteristics of various assessment factors. Field survey using satellite image clearly revealed the suitability of the alternative method compared to an existing method of land assessment. Furthermore, the alternative method of grading the land suitability improves the problem of using standardiZiation method and gives more flexibility, which makes this method very rational.

  • As GIS analysis method began to be introduced in late 1980's, studies of land development applying the GIS also started to be proceeded in various fields. Since 2003, Land Suitability Assesment has been adopted in order to prevent national land from development thoughtless for the environment and to plan appropriate national land management in terms of green development. Land Suitability Assessment System II based on diverse GIS analysis method such as Contour Analysis, Overlay Analysis, Network Analysis was particularly adopted to draft plans of specifying and altering of exclusionary zoning as well as installing and maintaining of urban planning facilities. But there has been a lot of problem, like an inaccurate basic data and assessment indicators, unmatched threshold, and contradicted evaluation result between each evaluating systems. Even though it is suited to an evaluation criteria, grade distribution is applied to start at 20, and development-centered evaluation result is offered. Now, we observed how suitability values and grading were changed, ordering to change grade distribution system from $20{\sim}100$ to $0{\sim}100$. In result, it showed changes of grades in some parcels. And in case of suitability values, 87% of parcels decreased to minimum 1 point, maximum 70 points. It means that changing grade distribution system of assessment system II doesn't have only influence on suitability values and grading but it is also an empirical analysis because of considering both development and maintenance.

  • 도시라는 광역지역의 확장을 분석하는데 위성자료는 매우 유용한 정보를 제공한다. 특히 한국항공우주연구원에서 운용중인 다목적 실용위성(KOMPSAT) 1호 영상자료는 해상도가 높아 도시지역의 분석에 유용한 정보를 제공하고 있으며, 과거의 항공사진 등을 복합적으로 활용한다면 도시의 확장 과정에 대한 시계열 분석이 가능하다. 도시의 확장 과정을 분석하여 그 정보를 추출하는 것은 새로운 도시계획을 위한 필수적인 기본 자료를 구축하는 중요한 역할을 할 수 있으며, 특히 2003년 개정 시행중인 국토의 계획 및 이용에 관한 법률은 도시기본계획 수립에 있어 도시의 성장 경향 등에 관한 기초조사를 의무화한 토지적성평가 제도를 도입하고 있다. 본 연구에서는 다목적 실용위성 1호 EOC 영상과 기타 원격탐사 자료를 복합적으로 활용하여 대전광역시 도시화 지역의 확장 추이를 분석하고 그 경향과 특성을 도출해 도시계획 수립에 원격탐사 자료를 활용할 수 있는 가능성을 제시해 보고자 한다.

  • 1999년 7월 청주권을 비롯한 7개 지방중소도시권은 친환경적 도시기본계획을 수립한 후 개발제한구역을 해제하도록 하고, 수도권을 비롯한 7개 대도시권은 보전가치가 낮은 지역을 위주로 부분적으로 해제하도록 하였다. 그리하여 표고, 경사도, 농업적성도, 식물상, 임업적성도, 수질 등 6개 항목에 대한 환경평가를 통해 개발제한구역에 용도지역이 지정되었다. 청주시의 경우 환경평가와 주민의견 반영 후 도시계획재정비에 따라 용도지역이 지정되었으나, 평지나 산림생산성이 떨어지는 곳은 낮은 환경등급을 받아 개발이 가능한 용도지역이 지정됨으로써 벨트형 녹지 유지가 어려워져, 시가지 팽창, 대전과 연담화, 도시 허파기능 상실 등의 가능성이 커지게 되었다. 따라서 청주권 개발제한구역의 시가화 영향을 토지피복, 지목, 용도지역 등의 변화를 통해 살펴보고, 6개 항목에 대한 환경평가 과정상 문제점을 고찰한 후, 개발제한구역의 해제 영향을 도시성장측면과 환경용량평가를 통해 규명하고, 전략환경평가의 적용방안을 모색하고자 한다. 전략환경평가의 시행을 위해서는 먼저 오염총량관리제, 국토의 계획 및 이용에 관한 법률에 의한 개발밀도관리구역, 수도권정비계획법에 의한 인구집중시설에 대한 개발총량규제 등이 반영되어야 할 것이다. 그리고 이미 시행중인 개발사업 및 개발계획중인 사업에 대한 누적영향평가와 함께 해당 지역에 대한 환경용량평가가 이뤄져야 하고, 아울러 개발제한구역 해제지역에 대한 사전환경성검토업무편람의 내용을 토대로 하여 환경평가항목에 대한 스코우핑, 환경평가 지표 개발이 이뤄져야 할 것이다.

  • This study proposes an approach to improve the accuracy of land assessment result focused on the Land Suitability Assessment. The detailed analysis processes are; (a) that they are analyzed considering resistance in distance measurement on the space characteristics of location, and; (b) that an assessment result is measured according to the threshold definition of membership function, which is applied in estimating conservation suitability. The assessment results are; firstly, the method considering resistance better reflects the local characteristics of area with worse accessibility including rivers and mountains than one by linear distance; secondly, the existing method that the maximum value of a target area is defined as the maximum threshold may draw a value evaluated lower than a threshold definition considering the distribution of measured indices. Finally, satellite images are overlapped with the assessed results, the applicability level from the approach proposed by this study is more coincident with the present status. The assessment method proposed by this study can be meaningful in view of that it improves the accuracy of Land Suitability Assessment. Furthermore, it can be applied as SDSS, which can support effective establishment of urban policies, in case of complementing the problems in executing the assessment system.
