  • In recent years, increases in impervious areas with rapid urbanization and land use changes are causing numerous hydrologic and environmental problems. In this study Low Impact Development (LID) was applied to investigate changes in runoff and peak runoff with LID plans. SWMM 5.0 was used to simulate LID Integrated Management Practices (IMPs) at study area. The SWMM estimated total runoff volume with conventional land use planning is (82.3%, 46.44 mm), (99%, 73.16 mm) greater than total runoff before urbanization, while total runoff with LID is (11.1%, 46.44 mm), (49%, 73.16 mm) greater than those before urbanization. With the LID adoption in land use planning, pervious area increases by 49.8% compared with that from the conventional urban land use planning, resulting in (32.7%, 46.44 mm), (23.6%, 73.16 mm) decrease in total runoff, and (32.6%, 46.44 mm), (18.5%, 73.16 mm) decreases in peak rate runoff. The results obtained from this study indicate that peak rate runoff, time to peak, and total runoff can be reduced with the LID in urban land use planning because the LID secures pervious areas with various LID IMPs. The SWMM simulated result using design storm data and the US EPA suggested CN values for various LID IMPs implies that how environment-friendly urban land use planning with the LID adoption is important for sustainable development at urbanizing watershed.

  • The objective of study is to propose theoretical basis for applying planning elements to Environment-friendly Public Land Development in integrated perspective of 'eco' and 'health'. For this purpose, First, the definition of 'Environment-friendly Public Development' and the interrelation between 'eco' and 'heath' as the component element of it are proposed. Secondly, based on internal and external case studies, eco and health related planning elements are deprived. And to assess the planning elements efficiently, representative planning elements are selected by each content. Thirdly, based on the analysis of specialist question, how the selected planning elements contribute to the improvement of human health and ecosystem is assessed. The result of study could be useful to reflect the regional condition and to predict the effect of the application.

  • The purpose of this study is to apply land use planning model (LUPM) to a test village. The LUPM was tested to Uhang village, Ucheon-myeon, Gangwon-do, and its parameters calibrated by land use data from 1973 to 1980. When two test cases were considered of its extended built areas of 10,600㎡ from 1980 to 1985 and 51,300㎡ from 1985 to 1992, there was good similarities between simulated and observed results with R$^2$ being more than 0.95. Land use transfer patterns to residential use could be very similarly simulated from LUPM when comparing the observed patterns, so, LUPM can be applied to the comprehensive simulation of land use change due to the village growth.

  • A spatial simulation model for rural and urban sprawl phenomena was developed with GIS and cellular automata techniques. The model finds out built-up areas invading toward rural areas required for development of existing urban area. Probability of land use change for optimizing the development area was determined using a land suitability analysis method interfaced with GIS methods, based on several criteria in terms of geographic and accessibility factors such as slope of land and distance from city center. Weighting values of the criteria were quantified by an analytic hierarchy process method. For model applicability test, the parameters of criteria were calibrated based on the changes in time series land use data of the test city for 1986, 1996, and 2000, which were classified by remote sensing techniques. Simulated and observed areas in land use maps for city shape of 1996 showed good similarities with each other through a morphology verification method. The model enabled us to evaluate the spatial expansion phenomena of cities considering boundary conditions, and also to simulate land use planning for rural areas in urban fringe.

  • This paper discusses the change of land ownership in the urban historical core of Kyungju city in the Period of Japanese occupancy(1910-45) based on the analysis of land register records. Kyungju city was not designated for the cities controlled by urban planning law which was set up in 1912 and 1934. The major purpose of this paper is to clarify the urbanization process of a Korean local city where the formal urban planning projects were not carried out. The focus of the study is the increase of the Japanese landowners and Japanization of the landscape. In the very beginning of occupation, Japanese already owned about 8% of the total land of the city centre where the old Kyungju castle had been located. The ratio of the land owned by Japanese went up to more or less 70% at the end of World war II. The process which the urban core had been replaced for the Japanese is very clearly traced from the analysis of a land register records.

  • Green belts can help to set boundary for city growth, provide ecological protection system and enhance the resilience of Beijing. During the implementation period of the current overall city planning of Beijing, the proportion of green space varies much among the sub-districts, villages and towns involved in the two green belts in the research. With this as starting point, by researching the correlations of 'city system factors' and 'planning policy factors' with the change in the scale of green space, the paper discussed the influential factors of implementing the planning of green space of Beijing, and conducted quantitative research, with such possible influential factors classified into 'city system factors' and 'planning policy factors'. Through multiple linear regression model, the paper tested the correlations of city system factors and planning policy factors (independent variable) with the increment in the construction land in green belts (dependent variable). Through influence to population aggregation and the expansion force of construction land, city system factors such as mountain land and water, house rent of unit area, accessibility of public transport and the newly-defined state-owned construction land generate correlation with the change in the scale of construction land in green belts.

  • The purpose of this study is to examine farmers' intentions, attitudes, and the type of filming they are involved in, including to provide supporting data for planning the agricultural strategy and Green Belt policy in Seoul. All the collected data was analyzed using the contingency tables and the Chi-square test using the SAS computer statistical package. The leaseholders did not want to change the current Green Belt policy for the study area, while the landowning farmers hoped for either its revision or dissolution. Both groups pointed out that the Green Belt policy resulted in the delay of development and complained about the difficulty of changing the land use type. The older generation supported the dissolution of the Green Belt, policy, as compared with the younger generation who wanted to maintain or modify the policy. The leaseholders worried that the possible changes in the Green Belt policy might affect the current agricultural land contract system, whereas the landowning farmers were very interested in easing restrictions on changing land use. The compensation plan, which is indemnified land owners for their loss of restrictions on land use, might be useful to sustain urban farming in the Green Belt.

  • This study aims to develop the Extended Urban Land Information System (EULIS) which can support the sustainable urban management. Although the existing Urban Land Use Information system (ULUIS) that aids the micro-level land use information is a good means for the understanding of urban spatial structure and district-level planning and management (such as urban design, redevelopment planning and district-level transportation planning, etc.), it has some limitations in supplying the information for sustainable urban management, such as environmental and traffic analysis, urban infrastructure's carrying capacity analysis, etc. The EULIS is designed to efficiently supply the information for sustainable urban management. For the successful construction of EULIS, the followings have to be considered. 1) the integration of topographic maps which contain the building's footprints and cadastral maps which contain the parcel's boundary, 2) the integration of EULIS and FM (Facility Management) system for the full utilization of information about capacity analysis of infrastructure, 3) the construction of standardized georeferencing system and spatial unit for the combined use of environment and traffic census data. This study shows 1) why EULIS is needed for the sustainable urban management and which elements are needed for the system,2) the E-R data model for the EULIS, 3) the strategies for the construction of EULIS and 4) the conclusion.

  • Spatial planning, is required to be conceptualized corresponding to the shifts in planning paradigm through logical and systematic approaches. The concept of planning, thus, should be considered in terms of not only the planning discipline but also the planning activities or practices. This study aims to review and examine the concept of spatial planning based on the different approaches of planning and analyze the difference between land use planning, then review a meaning of spatial planning in terms of its dimensions. The research range will be limited to only the concept of spatial planning and survey was carried on through collecting the secondary research data by literature reviews and both descriptive and comparative approaches will be applied concurrently. The key findings of the study can be found as follows: Firstly, spatial planning has been reviewed with regard to theoretical, practical and integrated approaches. Secondly, the concept of spatial planning has been examined in terms of definitions, dimensions and analysis criteria and then analyzed conceptual differences compared with traditional land use planning. Finally, a meaning of spatial planning has been highlighted based on the dimensions of spatial planning, such as future visions, policy toolbox, sustainable development and inclusivity.

  • This study is designed to suggest future development guidelines for leave-out lands in the land readjustment project area. For this purpose, physical conditions which affect living conditions were surveyed. The findings are follows. First, the living conditions in the lands are low with shortage of parking space and green area, narrow and low-performance road conditions, disordered fence and roof. Furthermore, illegal waste disposal made the condition even worse. Second, it is desirable to make separated plan for the leave-out lands because they have quite different living conditions from those of the land readjustment project area. Third, it is suggested that urban planning and architectural laws should pay attention to the leave-out lands to improve living conditions. It is also recommended that planning obligations for the leave out land should be imposed on land developers.
