The purpose of this study is to explain the types and causes of errors in zoning data that occur in the topographic map notification procedure, and to prepare a data maintenance plan. In Korea, like the United States, law-based land use regulation is dominant. In other words, according to the land use regulation method in the Act, the government designates zoning for all lots in the country, and landowners check the land use regulations of their land through the Korea Land use Information System. The land use plan confirmation document is important land information that affects the results of administrative dispositions such as land transactions between individuals or permission for development activities. However, there are data errors that occur during the current topographic map notification procedure and data construction process. Therefore, four local governments that can verify data by type were selected in consideration of local government conditions. A number of errors are first, errors in data construction and management in the Korea Land use Information System, and second, errors in lack of expertise that occur while the local government officials maintain data. Third, it was analyzed as an error from the relationship between the serial cadastral map and the zoning DB. Based on the above results, it is hoped that the results of this study will be reflected in the establishment of the KLIP and the reform of the legal system, which is currently underway after the establishment of the 「3rd the Korea Land use Information System Construction Plan」.

This study aims to POE(Post-Occupancy Evaluation) analyze the characteristics of residents and their demands on community facilities by types of supplying housing, which can be the basis for making the housing regulations. The following five types of housing are considered in this study ; 1) National Rental Housing(L), 2) Public Rental Housing(L), 3) Permanent Rental Housing(S), 4) Public Rental Housing(S), 5) Private Rental Housing. We surveyed 527 residents from 20 housing complexes in those four housing types. First, each housing type has different household characteristics. Second, the criteria for housing selection are different. Third, local community activities and satisfaction are different in each housing type. Lastly, residents are generally satisfied with service facilities, but their satisfaction level and the facilities they need are different depending on housing type, accordingly. The housing community space plan be should be improved to the amount of areas of community facilities.

The purpose of this research was to investigate the characteristics of urban ecotopes and to classify ecotopes systematically from them. Total of 15 characteristics for classification of ecotopes were selected, and there were categorized 3 factors, that is abiotic, biotic and anthropological factors. The ecotope types in the study area were classified into 67. The classification of ecotope was made with SPSS for Windows Version 10.0 on the basis of the 15 characteristics. As the results of cluster analysis using the average linkage method between groups, groups of ecotope type were divided into 15 clusters. It was known that there was not a great difference in an affinity as the result of overlapping the maps of ecotope type and land use type. This research suggested characteristics for classification of ecotopes, but there was a limit to Set the objective method for grade classification because of lacking in the basic data, the research of characteristics will be accomplished continuously.

Hanok is Korea's traditional housing, which is build detached unit. Most of the People who live in the environment of residential high-rise apartments likes new residential environment, and pursue eco-friendly homes, health homes, especially traditional Hanok was reassure potential. In urban context, resident think more compact land use in Hanok also, because Hanok is dissatified in compact land use, and it should be build as more economic aspect. The purpose of this study is to propose a typology which traditional Hanok also can be build higher land use and traditional values as a modern housing type; First of all, clustered Hanok is formed by traditional houses and interior spaces in modern house., and its types are configured by lifestyle of modern and image element of traditional Hanok. This kinds of clustering Hanok can be seen from historical city, but the trends is a minority of the housing type and form. Now, the modern clustering Hanok, even though handful of cases, appears as sustainable housing type, its possibilities as a new housing should be more detailed researches. A elements of Modern cluster Hanok discused in layout, plan, envelopment of house, structure, roofs, and the coordination of the element can be so much diverse.

The urban ecosystem, unlike the natural ecosystem, has been affected by the urban environment, so the existences of normal creatures have been threatened and eventually the stability has declined to consist of those that have adapted to such. Therefore, by creating a list of such organisms, their number of variety can be found out and their ecological distinction can be understood. Because flora is known to be an ecological index reflecting region's effects of human and societal environments, weather, and climates, it is a useful method of finding out the ecological position and distinctiveness of that region. The study site is part of watershed at Yangjae Stream, Kahngnam-ku, Seoul. In this study, the difference of flora in each land use type are investigated by plant identification. The purpose of this study is to evaluate the city's plant surviving environment, and eventually to contribute to the restoration of urban green spaces by finding out the plants which are appropriate for the corresponding environment. After doing the study, it was found that the urban forest is the most stable urban ecosystem while the urban park is seriously disturbed, and ecologically unstable. The urban stream is also disturbed continuously.

As a rational decision-making process of county-level area development, this study designed 3-step framework : function-giving(areal analysis) on unit planning area by decision matrix of land suitability, check of typical characteristics of each function area and formulation of its future development strategies. Two alternatives were suggested as the areal analysis method, of which one is equal ordering / valuing technique of checking indices for land suitability classfication and the other preferential weighting technique. And then, under the algorithm specially defined in this study, land suitability maps(Fig.2,3) of the case study area (Seungju-county area, Chonnam-province, Korea) were drawn from the areal analysis results. By use of land suitability classification results, unique characteristics of typical function areas were defined (on 7 types of alternative 1 , 8 types of II ) and their future development strategies were formulated in the case study area, According to the categorization criteria in this study, all the villages of the case area were classfied as a suitable type of function areas illustrated in this study.

This study investigates the impacts of urban land-use fraction and temperature advection on the urban heat island intensity over the Seoul metropolitan area using the UM (Unified Model) with the MORUSES (Met Office Reading Urban Surface Exchange Scheme) during the heat wave over the region from 2 to 8, August 2016. Two simulations are performed with two different land-use type, the urban (urban simulation) and the urban surfaces replaced with grass (rural simulation), in order to calculate the urban heat island intensity defined as the 1.5-m temperature difference between the urban and the rural simulations. The land-use type for the urban simulation is obtained from Korea Ministry of Environment (2007) land-use data after it is converted into the types used in the UM. It is found that the urban heat island intensity over high urban-fraction regions in the metropolitan area is as large as 1℃ in daytime and 3.2℃ in nighttime, i.e., the effects of urban heat island is much larger for night than day. It is also found that the magnitude of urban heat island intensity increases linearly with urban land-use fraction. Spatially, the estimated the urban heat island intensities are systematically larger in the downwind regions of the metropolitan area than in the upwind area due to the effects of temperature advection. Results of this study indicate that urban surface fraction in the city area and temperature advection play a key role in determining the spatial distribution and magnitude of urban heat island intensity.

Groundwater monitoring wells (about 70 wells) were extensively installed in 28 sites surrounding Lake Texoma, located on the border of Oklahoma and Texas, to assess the impact of geochemical stressors to shallow groundwater quality. The monitoring wells were classified into three groups (residential area, agricultural area, and oil field area) depending on their land uses. During a two-year period from 1999 to 2001 the monitoring wells were sampled every three months on a seasonal basis. Water quality assay consisted of 25 parameters including field parameters, nutrients, major ions, and trace elements. Occurrence and level of inorganics in groundwater samples were related to the land-use and temporal change.

The purpose of this article is to examine land use change in the fringe area of a metropolitan city through multi-temporal data analysis. Change detection has been regarded as one of the most important applications for utilization of remotely sensed imageries. Conventionally, two images were used for change detection, and Arithmetic calculators were generally used on the process. Meanwhile, multi-temporal change detection for a large number of images has been carried out. In this paper, a digital land-use map and three Landsat TM data were utilized for the multi-temporal change detection Each urban area map was extracted as a base map on the process of multi-temporal change detection. Each urban area map was converted to bit image by using boolean logic. Various urban change types could be obtained by stacking the urban area maps derived from the multi-temporal data using Geographic Information System(GIS). Urban change type map was created by using the process of piling up the bit images. Then the urban change type map was compared with each land cover map for the change detection. Dalseo-gu of Daegu city and Hwawon-eup of Dalsung-gun, the fringe area of Daegu Metropolitan city, were selected for the test area of this multi-temporal change detection method. The districts are adjacent to each other. Dalseo-gu has been developed for 30 yeais and so a large area of paddy land has been changed into a built-up area. Hwawon-eup, near by Dalseo-gu, has been influenced by the urbanization of Dalseo-gu. From 1972 to 1999, 3,507.9ha of agricultural area has been changed into other land uses, while 72.7ha of forest area has been altered. This agricultural area was designated as a 'Semi-agricultural area'by the National landuse Management Law. And it was easy for the preserved area to be changed into a built-up area once it would be included as urban area. Finally, the method of treatment and management of the preserved area needs to be changed to prevent the destruction of paddy land by urban sprawl on the urban fringe.
