The primary purpose of this study is to identify the characteristics of land use change at the urban fringe. For this purpose, the Daegu Metropolitan City is selected as a study area. Land use changes between 1990 and 2000 in fringe areas are identified by processing Landsat TM5 imageries. The main findings are follows: First, land development has been driven by residential development, especially large-scale residential development encouraged by the two-million housing construction plan. Second, the type and size of the land use conversion are not identical across the study area. For example, the main land use type of the newly developed area of Buk-gu is residential use while that of Suseong-gu is public use. Third, most of residential development type is a high-density development which is quite different from American type of low-density development.

The purpose of this study is to evaluate landscape characteristics of watersheds in the Nakdong River Basin for identifying the groups of watershed with similar landcover patterns by using Geographic Information System and statistical technique. According to the results based on the cluster analysis using cluster analysis tool in the ArcGIS 8.3 program, 22 sub-watersheds were classified into three types; "Forest watershed", "Agriculture watershed", and "Urban watershed". In the forest watershed that has the least potential of ecological disturbances by human, a forest management approach based on geographic conditions and coverage types, etc., should be developed to sustain the ecological and environmental functions of forest. For the agriculture watershed, environmental-friendly agricultural techniques should be performed in the particular enhancement of riparian buffer zone to the prevent direct inflow of soils, fertilizers, and other chemicals into the stream network. Finally, in the urban watershed, an environmental-friendly plan that may increase the ratio of pervious surface and amount of green-space to should be reserved.

최근 새만금 농업용지에 아그로파크 개념을 적용하기 위한 시도가 이루어지고 있어 새만금 간척지에 현실적이고 적합한 아그로파크 개념을 반영한 농업용지를 개발할 필요가 있다. 그러나, 현재의 새만금 토지이용계획 상 주요 11개 단지들은 네덜란드의 아그로파크처럼 같은 장소에서 서로 다른 기능들이 공간적으로 네트워크로 연결된 개념보다는 각각의 기능을 가진 독립된 공간처럼 단지별로 나누어져 있어 단지들 간 종합적으로 연결된 개념으로 보기 힘들다. 따라서, 본 연구에서는 새만금 농업용지에 아그로파크를 도입할 수 있는 두가지 방안을 제시하였다. 첫째, 현재의 토지이용계획을 고려하지 않았을 때, 어느 특정 구역에 자원 순환 등의 연결고리를 갖고 생산, 가공, 유통이 한 곳에서 이루어질 수 있는 아그로파크를 조성하여 확대할 수 있도록 토지이용계획이 수정될 수 있는 방안이다. 이 경우 농업용지는 지속적으로 아그로파크들의 확장에 따라 단계적으로 확대 개발될 수 있고, 장기적인 관점이 필요한 방안이다. 둘째, 현재의 토지이용계획을 고려할 때, 아그로파크 기능 발휘를 위해 농업용지 각 단지별로 연계 가능 기능들을 연결하는 방안으로, 아그로파크 시범단지를 조성하는 것을 제시하였다. 두 경우 모두 아그로파크 기능 발휘를 위해 새만금 농업용지 종합관리센터가 구축되어야 한다. 향후 성공적인 아그로파크 조성을 위해 이 두가지 방안에 대한 세부 계획과 설계 기술 개발을 위해 지속적인 연구가 필요하다.

Sustainable development is important because the ultimate objective is efficient development combining the economic, social, and environmental aspects of urban conservation. Despite Korea's rapid urbanization and economic development, the distribution of resources is inefficient, and land-use is not an exception. Land use distribution is difficult, as it requires considering a variety of purposes, whose solutions lie in a multipurpose optimization process. In this study, Yangpyeong-eup, Yangpyeong, Gyeonggi-do, is selected, as the site has ecological balance, is well-preserved, and has the potential to support population increases. Further, we have used the genetic algorithm method, as it helps to evolve solutions for complex spatial problems such as planning and distribution of land use. This study applies change to the way of mutation. With four goals and restrictions of area, spatial objectives, minimizing land use conversion, ecological conservation, maximizing economic profit, restricting area to a specific land use, and setting a fixed area, we developed an optimal planning map. No urban areas at the site needed preservation and the high urban area growth rate coincided with the optimization of purpose and maximization of economic profit. When the minimum point of the fitness score is the convergence point, we found optimization occurred approximately at 1500 generations. The results of this study can support planning at Yangpyeong-eup.ausative relationship between the perception of improving odor regulation and odor acceptance.

농업－공동체 임업은 토지－나무－인간 사이의 관계를 폭넓게 포함하고 있으나 이 논문에서는 농업－공동체 임업활동이 베트남의 산지의 지속가능한 이용에 초점을 두고 있다. 농업－공동체 임업(AF와 CF)은 베트남에서 시급한 국가우선사항이 된 개발과 보전을 함께 고려할 수 있는 기능을 지닌 것으로 받아드려지고 있다. 베트남에서 AF와 CF를 동시에 지원할 수 있는 자원은 한정되어 있으며, 제약 사항은 위협적이고 시급한 상황이고, 황폐화가 진행될수록 복원은 어려워지는데, 농업의 생산성 감소에 따른 산촌주민들의 가족 부양을 위한 생태계 파괴도 가속화되고 있는 것으로 조사되었다. 이 연구는 농업－공동체 임업활동이 베트남의 산지 자원의 지속가능한 이용에 있어서의 연관된 문제들, 발전에의 제한요인, 특히 정책 제한요인을 분석하고 베트남 농업－공동체 임업 개발의 방향을 제시하고자 하였다.

The Republic of Korea is planning to build the now Multi-functional Administrative city (NMAC). The purpose of this paper is to suggest the conceptual framework for this new city that relies on the Korean geomancy, oriental viewpoint on man and nature relationship, particularly in Korea. According to the Geomancy which could conceptualize the human-environment relationship in the site, the overall landscape image of the city could be symbolized by two flying crane with three Taegueks. In transforming the overall landscape image to urban form, two diamonds which means eternity and strength arises from the western spatial viewpoint, as means to protect and harmonize the human, land and mountain relationship in this site and the symbolic meaning of this site as generative and sacred place in Korean people's mind. On the one hand, through juxtaposing of the two diamonds a geometric structure shows up, on the other hand the main axis of the city could be established from two crane and three Taegueks. On the North-South axis from the core of the symbolic green axis, symbolic things will be located, and the administrative offices will be Placed on the East-West axis. Peripherals of the central axis also play a role in developing overall land use from image. The buildings and residents could be arranged and located according to undulations and this is based on the oriental theory of geomancy. We can build cultural amenities on the head part of the crane and on the core area.

There have been rapid increases to the demands for modeling diverse and complex spatial phenomena and utilizing spatial data through the computer across all the aspects of society. As a result, the importance and utilization of remote sensing and GIS's(geographic information systems) have also increased. It can produce digital data of enormous accuracy and value by incorporating remote sensing images into GIS analysis technology and make various thematic maps by classifying and analyzing land cover. Once such a map is made for the target area, it can easily do modeling and constant monitoring based on the map, revise the database with ease, and thus efficiently update geo-spatial information. Under the goal of analyzing changes to land cover along the road by combining the remote sensing and GIS technology, this study classified land cover from the images of two periods, detected changes to the six classes over ten years, and obtained statistics about the study area's quantitative area changes in order to provide basic decision making data for urban planning and development. By analyzing land use along the road, one can set up plans for the area along the road and the downtown to supplement each other.

Unplanned land use, that is, unplanned development, causes various negative externalities. In the past, Korea has experienced significant socio-economic costs due to reckless development centered on the boundary between urban and non-urban areas.. Unplanned land use can be viewed as a result of the interaction of various factors.. Therefore, it is difficult to develop in areas where unplanned land use occurs intensively. It is necessary to strengthen legal and institutional measures so that negative externalities do not persis. In this study, we present a spatial analysis methodology to effectively find spatial clusters where unplanned land use is concentrated. By demonstrating and applying this to individual development activities that occurred in Asan City, we examine the usefulness of information to support decision making when establishing mid-to-long-term growth management strategies at the local government level.

In this paper, we propose a system to detect spatial structures in land cover maps and to detect time-series spatial structure changes. At first, the proposed system detects patches in a certain area at different times and calculates their measures to analyse spatial structure patterns of the area. Then the system conducts patch mapping among the detected time-series patches and decides 6 types of patch changes such as keeping, creating, disappearing, splitting, merging, and changing in a mixed way. Also, the system stores the patch-based spatial structure patterns of time-series land cover maps in binary form to extract changes. This demonstrated that the proposed change detection system can be used as a basis for planning the reconstruction of the urban spatial structure by measuring the degree of urban sprawl.
