The rebuilding or redevelopment of buildings in the Readjustment Project District is generally built high-rise buildings. It sometimes makes our residential area to be uniform in height and disharmony with surrounding houses and infrastructure. Then this research examines the landscape effects of the height of buildings built using landscape simulation on hillside and level ground. We suggested that it was desirable for a land readjustment project district to be managed by District Plan and Development Density Controlled Area. In addition, a consideration for the introduction of Average Floors is needed to mitigate the uniform and disharmony with surroundings.

To designate rural landscape spatially, land use and topographic features for 383 of "Ri"s or "Dong", which is a basic administrative unit in Korea, were analyzed using GIS application. We have categorized rural landscape into three types such as agricultural, natural and urban landscape by land use. On the basis of spatial landscape pattern, rural area could be classified into 6 groups of Mountainous area (MA), Mountainous village area (MV), Developing mountainous village area (DM), Plain agricultural area (PA), Developing plain village area (DP) and Urbanized area (UA) according to the ratios of land for agricultural and urban use as the criteria. In MA, the ratio of upland area including orchard was slightly larger than that of paddy, while that of paddy was about 1.5 times larger than upland in other groups. Forested area was distributed more than two-thirds among natural landscape area in MA, MV and DM. In plain types (PA and DP), the ratio of irrigated paddy was extremely larger than partially irrigated paddy and the ratio of water body area among the natural landscape area was two times as large as that of forested area. The ratio of land for industrial and livestock facilities among urban landscape area were 20% or more in MV, DM and DP, and it means that these facilities are mainly distributed in the developing ru ral area where residents and industry are closely related each other. According to the relative ratio of sloped land of 6 categorized areas, the MA area have lots of land with E and F slopes and MV and DM have all grades of sloped land evenly distributed in relative to other types of rural landscape. It has been showed that PA, DP and UA occupied more than two-thirds of land with A or B slope. In case of the analysis of topological distribution in 6 types of rural landscape, there were overwhelmingly lager highland areas in MA. Conclusively, we have confirmed that 6 types of rural landscape classified by land use pattern in 3 categorized areas such as agricultural, natural and urban landscape area would be useful for the management of rural area. For development of sustainable agriculture and the preservation of rural amenity, proper management ways should be properly applied according to rural landscape patterns.

본 연구는 경상남도 창원시 삼각점의 GPS 데이터를 활용하여 오차수준 및 지역적인 특성 등을 종합적으로 분석하여 봄으로써 향후 지적세부측량을 위한 지적기준점측량 수행 시 보다 정확한 성과가 산출될 수 있는 방안을 모색하여 보고자 하였다. 연구결과, 토지조사사업 당시 설치된 삼각점의 경우 삼각점 자체의 자연적 인위적 이동이 없을 경우 대부분 삼각점의 성과가 안정적으로 나타나므로 지적기준점 성과결정시 기지점으로 사용할 삼각점은 토지조사 당시 설치된 삼각점을 우선적으로 선정하여야 할 것으로 판단되었다. 또한 본 연구결과에서 안정적인 성과로 제시된 삼각점을 기준으로 하여 지적기준점의 성과를 결정할 경우 향후 지적기준점이 망실되어 재설치 하더라도 항상 동일한 측량성과를 유지 관리할 수 있을 것으로 보인다.

전 지구영역에 대해 1km 의 해상도로 제공되는 새로운 개념으로 완성된 지표 변수데이터 베이스인 Ecoclimap-1이 소개 된 바 있다. 이것은 기상과 기후의 모델에서 토양과 식물과 대기 사이의 이동 모식을 설명하기 위해 고안 되었으며, 이러한 Ecoclimap-1은 토지피복지도와 기후기도를 중첩하여 얻어진 Ecosystem 지도를 기본 주제도로 사용한다. 하지만 중첩한 결과 같은 class 에 포함되더라도 내부 class 에서의 식생의 시간 변동성은 여전히 높게 나타난다. 이와 달리 Ecoclimap-2는 새로운 방법으로, SPOT/VEGETATION S10 NDVI 자료를 이용하여 토지피복을 보다 동질의 하위 집단으로 분류 한다. 본 연구 에서는 이러한 Ecoclimap-2의 일환으로 동북 아시아 영역의 생태기후지도를 제공하고자 한다. 이러한 Ecosystem map 은 앞으로의 기후 모델 연구에 있어 중요한 base map 으로 사용 되어질 것으로 보이며 또한 생태계모델, 기상 모델의 중요한 input 자료로서 쓰여 질 것으로 사료 된다.

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.

I examine in this paper the change of land use and the development of desertification in Horqin desert, east Inner Mongolia, China. The change of land use in this area can be summarized as the increase of agricultural field and intensive livestock farming. The agriculture and livestock farming in semi-arid area such as Horqin desert raised the problem in the management and use of water and vegetation. This problem led to desertification. The types of development of desertification in this area could be classified as follows: the mobile sand dune extension, the riverside shifting sand flat extension, the shifting sand speck extension around settlements, and the shifting sand speck extension in agricultural Held and grassland. There have been political or social movements such as the Great Leap Forward, the Cultural Revolution and the Reform and Open Policy in the background of land use change and desertification. Specially, the Great Leap Forward and the Cultural Revolution played an important role in the land use change and desertification in this area. Since 1990s, there has been some kind of policy in the control of desertification. However, it is necessary for the controling desertification of this area to consider the globalization and marketization, the survival and profit of peasants and livestock farmers, and the disturbrd and fixed population and land use structure in this area since 1949.

The policy which encourages people to use cars on the road has been based on the growth of economy in Korea. It has also caused the concentration and overcrowding in Seoul. That's because the increasing number of people possessing cars interconnects with the urban development. The transportation is a derived demand; so many scholars have recognized the importance of understanding the relationship between urban land use and transport. Considering such importance, this study theoretically compared the developed urban land use-transportation models each other and outlined the particular models briefly. Models were categorized by 2 types; optimizing model and predictive mode. Predictive model is also defined by static model, entropy based model, spatial-economic model, and activity model. After studying models, we investigated other major cities in America. This process is the pre-step for transport policy assessment. Through careful literature review, we can finally develop the integrated land-use transportation model in Seoul metropolitan area. In addition, we will be able to deal the changes of traffic demand pattern under U-Society. Consequently, the results of this study can be applied to ITS projects in the future.

This study predicted urban green spaces for 2020 based on two scenarios keeping or freeing the green-belt in the Daegu metropolitan city using a hybrid Cellular Automata(CA)-Markov model and analyzed the spatial dynamics of urban green spaces between 2009 and 2020 using a land cover change detection technique and spatial metrics. Markov chain analysis was employed to derive the transition probability for projecting land cover change into the future for 2020 based on two land cover maps in 1998 and 2009 provided by the Ministry of Environment. Multi-criteria evaluation(MCE) was adopted to develop seven suitability maps which were empirically derived in relation to the six restriction factors underlying the land cover change between the years 1998 and 2009. A hybrid CA-Markov model was then implemented to predict the land cover change over an 11 year period to 2020 based on two scenarios keeping or freeing the green-belt. The projected land cover for 2009 was cross-validated with the actual land cover in 2009 using Kappa statistics. Results show that urban green spaces will be remarkably fragmented in the suburban areas such as Dalseong-gun, Seongseo, Ansim and Chilgok in the year 2020 if the Daegu metropolitan city keeps its urbanization at current pace and in case of keeping the green-belt. In case of freeing the green-belt, urban green spaces will be fragmented on the fringes of the green-belt. It is thus required to monitor urban green spaces systematically considering the spatial change patterns identified by this study for sustainably managing them in the Daegu metropolitan city in the near future.
