  • This study was performed to analyze the effects of a water circulation green area plan on non-point source pollution in Gimhae South Korea. A quantitative analysis of Arc-GIS data was conducted by applying a watershed model based on Fortran to investigate the changes to direct runoff and pollution load. Results showed that prior to the implementation of the water circulation green area plan in Gimhae, direct runoff was $444.05m^3/year$, total biological oxygen demand (BOD) pollution load was 21,696 kg/year, and total phosphorus (TP) pollution load was 1,743 kg/year. Implementation of the development plan was found to reduce direct runoff by 2.27%, BOD pollution load by 1.16% and TP pollution load by 0.19% annually. The reduction in direct runoff and non-point source pollution were attributed to improvements in the design of impermeable layers within the city.

  • The agricultural population, the farming, the agriculture of our country has been decreased more rapidly than those of other countries. Also, the changing speed of the rural village in Korea has shown a similar trend. By considering the urbanization process and migration state caused by the economic growth and the increasing level of relative poverty in comparison with the urban area, it has been necessary to go through the impoverishment and slum-orientation of the rural area. In our country, the rural village became old age. So, the collapse is predicted to a population shortage if such trend is continued in the village society. according to investigate, Many urban peoples have opinion that migrates to a farm village. but those not migrate to rural community. The mainly reason is low life environment. therefore it is need the plan that the urban people migrates to a rural village, and must have the plan to be engaged in the agriculture. lt was the rural-fishing New Town development project that started in 2009 for 30~40 years's urban people. This study is about characteristic and improvement of Rural-Fishing New Town development project.

  • This study aims at drawing implications for Korea's urban growth management policies from U.S.A's experience on this issue. This study analyzes two types of contradictions in planning and implementing urban growth management policies: 1) value conflicts in goal setting and 2) contradictions among different level of governments (local, province, nation). As mentioned by Campbell (1996), there are three types of conflicts in objective values (efficiency, equity, and environment protection): property contradiction between economic growth and equity, resource conflict between efficiency and environment protection, and development conflict between equity and environment protection in urban growth management policies. In implementing urban growth management three types of conflicts in goal values should been taken into consideration. Contradictions among local governments, province, and central government are also found in implementing growth management policies. The lessons from the United State are as follow: 1) growth management plans are initiated by the local government and during the planning process adjacent local governments review a local government's growth management plans and give inputs for the plan, 2) local government and State work together for growth management planning and specially, the State provides technical and financial assistance to local government, and 3) the State plays leading roles in local government's planning and implementing of growth management policies with carrot and stick policy.

  • The purpose of this study is to examine urban built environments associated with the walking behavior in order to identify the problem of urban infrastructure from the perspective of Universal design theory. Using the walkability criteria developed based on the findings of previous studies on Universal design theory and walking environment, the urban built environments in old town area of Seoul were evaluated. The results of the evaluation indicated that the pedestrian infrastructure in the study area had several shortcomings to improve in order to provide walking-friendly environments. First, the pedestrian infrastructure for visually impaired people were severely limited. Second, walking traffics in large portion of the street networks were interrupted by a variety of obstacles such as parked cars, signboards, and illegal street shops. Third, there were certain areas where the quality of pavement was not properly managed. In summary, this study provides an empirical data to understand the current situation of pedestrian infrastructure in the urban areas. Improvement of pedestrian infrastructure is needed to address the issues related to the mobility of the disabled people. It is also recommended to construct the GIS data on walking environment in order to develop and mange a long-term public investment plan for walking-friendly urban environments.

  • Urban development and industrialization cause many problems on urban environment such as climate changes, natural disasters and a decreasing number of species. Problems on urban environment are the main factor of that lower the quality of life and obstruct continual development. As a result, eco space becomes the important part of a urban planning. This research, building plan U-Eco city which is establishing with the clean environment and high technology for solve the development thoughtless for the city environment problem and ecological problem. We suggest U-Eco space system which accreted with Ubiquitous technology to three physical divisions, which are lithosphere (land), hydrosphere (water), and aerosphere (air), that interact with the whole biosphere by forming the system. It has composed with U-Green belt that corresponds to lithosphere, U-Blue belt that is applicable to hydrosphere, and U-White belt that comes under aerosphere.

  • This study was carried out for the purpose of understanding the situation of the urban forest and presenting basic data bases for a proper management plan through the analysis of forest vegetation and soil characteristics. In three representative urban forests of Deajeon, we analyzed the differences of vegetation and soil properties in each geological location. The indices of ecological health such as Species Diversity and Maximum Species Diversity are increasing in the order of Namseon Park, Wolpyung Park and Mt. Bomun; the first is in the center of the city, the second is well-conserved inner-city park and the third is in the border of the city. In the soil analysis of Namseon Park where human disturbance is strong, the surface fuel bed was very thin just 0.5cm and the soil was harder than the other two urban forests, the soil hardness was $0.5{\sim}3.7kg/cm^2$. All three urban forests showed low $pH_{1:5}$ under 5.0 except Robinia pseudo-acasia association of Wolpyung and low exchangeable cation level. These results say that the urban forests of Deajeon have been being acidified severely and the eluviation of exchangeable cation is proceeding. The organic matter and the available phosphate level was lower than the average level of Korean forest. It means that nutrition supply is not sufficient. In Daejeon urban forests, the management plan of urban forest is necessary according to the analysis result of vegetation and soil.

  • Management practices and ordinances for urban scenic view protection are varied by cities because they have their distinctive nature and social environment. Therefore landscape management methods for urban scenic views are generally varied by the characteristics of city landscape and ordinance. This case study for scenic view protection practices in U.S.A. is very meaningful and appropriate because cities initiate a plan and/or an ordinance to manage urban scenic view in Korea. Urban scenic view protection methods were analyzed based on followings: 1) how to select scenic view resources and define spatial areas for preserving them, 2) how to control building height, open view corridor and guide landscaping and 3) how to carry out view protection methods and organize them in laws or ordinances. Findings of this study will be applied usefully in the development of urban scenic view protection methods in Korea.
