The purpose of this study is to investigate the actual condition of commercial use of housing site in residential development complexes, and to derive effective future development plan by analyzing the influence of penetrating factors of commercial use. The foJlowing are the results of the analysis. First, characteristics of roads showed that the wider the widths of roads adjoining individual lots have more influences on commercial use penetration. This means that non-residential facilities tend to be located on regions where frequencies of uses are high, preferring regions having good transportation accessibility. Second, characteristics of adjacent usage showed that the distances of common housing, neighborhood facilities, schools to single-detached residential units acted as a factor for higher penetration ratio of commercial use when they were closer.ors an opposite, it showed as distances to parks were further, the penetration ratio were higher. This can be inferred that the condition of detached houses located closer to parks have pleasure environment, and act as a factor preventing commercial use penetration. Third, the official land price presents as a form of quality, as the analysis showed that the higher official land price, the more it acts as a factor increasing the penetration ratio of commercial use.

${\cdot}$ 한국토지개발공사는 전국 37개 택지개발사업지구에서 단독주택지 5,493필지(361,127평), 상업용지 및 업무용지 1,465필지(389,736평)을 수의계약의 방법으로 매각하고 있다. ${\cdot}$ 수의계약으로 매각하는 단독주택지를 매입하는 경우에는 주택공급에 관한 규칙 제 17조의 규정에 의한 아파트 재당첨금지 규정 (민영 5년, 국민 10년)이 적용되지 않는다. ${\cdot}$ 토지시장이 비수기이고 현재 토지가격이 부동산 경기의 침체국면에 있는 가격임을 고려할 때 실수요자에게는 유리한 상황이라 할 수 있다.

This paper defined the concept of unsold land and diagnosed the cause of unsold land of LH business site. The results are showing as follows. First, unsold land is defined as land could not be sold until the completion of the project, and plan to sell the unsold land can be changed partially. Second, the status of unsold land in the 226 project sites were analyzed. $146km^2$ area corresponding to 74.8% of the total capital area($195km^2$) are unsold. By purpose, co-residential($38km^2$), industry($21km^2$), exclusive residential($16.4km^2$), commercial business($12.5km^2$), education($10.2km^2$) was larger in order. Third, value enhancement target project sites were selected and its symptoms and the cause of unsold land were analyzed. For the project site over average unsold rate, 6 sites located in province and 2 sites located in capital region were selected through collecting the practitioners and expert opinion. These 8 sites are characterized that sale of land for medium and large co-residential, urban support facilities, block-shaped house and attached house was inactive. Also, these sites commonly experienced economic fluctuations, changes in market demand, supply and demand mismatch, inflexible planning standards.

This study is to derive a project model based on potential demand for Korean-style houses, focusing on new town detached housing sites that LH supplies and to test validity of the derived model and to present the direction and supply methods of the projects. The existing high-class new town Korean-style housing developments that have been considered were found to have little business value due to problems in choice of location and discordance of demand, so 6 types of projects were established through the methods of changes in planned scale, combined use, and subdivision of plot of land based on the results of survey. The type that has the highest business value among the project models was block-type multifamily houses, and this can be interpreted as the increase in total construction area leading to increase inrevenues of allotment sales due to economies of scale. The feasibility of mass housing model in which small-scale Korean-style houses are combined with amenities was found to be high, and if the same project conditions as those of the block-type multifamily houses are applied, the business value of the Korean-style tenement houses was found to be high. Besides, the high-class housing models within block-type detached housing areas are typical projects that the private sector generally promotes, and the construction cost was found to be most expensive with 910 million won per house. In order to enhance the business value of the Korean-style housing development, collectivization such as choice of location, diversification of demand classes, optimization of house sizes, and combination of uses is needed. And in order to adopt Korean-style houses in the detached housing sites, the adjustments and division of the existing planned plots are needed, and the strategies to cope with new demand through supplying Korean-style housing types of sites can be suggested. Also breaking away from the existing uniform residential development methods, the development method through supplying original land that is natural land not yet developed besides basic infrastructures (main roads and water and sewage) can be considered, and as the construction of more than 1~2 stories building is impossible due to the structure of Korean-style house roof and furniture. So it can be suggested that original land in the form of hilly land is considered to be most suitable to large-scale development projects.

Modeling urban climate caused by land use conversion is critical for human welfare and sustainable development, but has hampered because detailed information on urban characteristics is hard to obtain. With the advantage of satellite observations and the new statistical boundary system, this paper measures the economic and environmental effects of green area loss due to land use conversion in urban areas. To perform this purpose, data were collected from the various sources basic statistical unit data from the National Statistical Office, digital maps from the National Geographic Information Institute, satellite images, and field surveys when necessary. All data (maps and attributes) are built into the geographic information system (GIS). This paper also utilizes Landsat TM 5 imagery of Daegu city to derive vegetation index and to measure average surface temperature. The satellite data were examined using standard image processing software, ERDAS IMAGINE, and the results of the digital processing were presented with ARCVIEW(v.3.3). SAS package was used to perform statistical analyses. This study presents that there exists a strong relationship between land use change and climatic change as well as land price change. Based on results of the analysis, this paper suggests that planners should implement effective tools and policies of urban growth management to detect environmental quality and to make right decisions on policies concerning smart urban growth.
