  • The purpose of this study was to analyze the landscape changes at Su-ji and Gi-heung in Young-in city using FRAGSTATS Model. Landscape Indices obtained by this model can explain the structural change of urban green zone and fragmentation resulting from development. As results of this study, Gi-heung showed worse quality of landscape in 2007, comparing 2000. However, in Su-ji, there were several better landscape indices in the same 2007/2000 comparison, even though the little shrinking of green zone and separation of core area. It could assume that the reason was caused by conservation policy of urban green zone. This study could provide the useful methods for finding the problems and searching the alternatives considering the development of urban green zone.

  • This study investigates the factors that affect China's air pollution using city-level panel data and spatial econometric models. We address three air pollutants ($PM_{10}$, $SO_2$, and $NO_2$) present in 30 cities in China between 2004-2012 using global OLS and spatial models. To develop the spatial econometric analysis, we create a spatial weights matrix to define spatial patterns based on two neighborhood criteria - the queen contiguity and k nearest neighbors. The results show that the estimated coefficients are relatively consistent across different spatial weight criteria. The OLS models indicate that the effect of green spaces is statistically significant in decreasing the concentrations of all air pollutants. In the $PM_{10}$ and $SO_2$ analyses, the OLS models find that the number of buses and population density are also positively related to a reduction in the concentration of air pollutants. In addition, an increase in the temperature and the presence of secondary industries increase $SO_2$ and $NO_2$ concentrations, respectively. All spatial models capture a positive and significant effect of green spaces on reducing the concentration of each air pollutant. Our results suggest that green spaces in cities should receive priority consideration in local planning aimed at sustainable development. Furthermore, policymakers need to be able to discern the differences among pollutants when establishing environmental policies.

  • Climate change is intensifying storms and floods around the world. Where nature has been destroyed by development, communities are at risk from these intensified climate patterns. This study was to suggest a methodology for estimating flood vulnerability using Potential Flood Damage(PFD) concept and classify city/county about Potential Flood Damage(PFD) using various typology techniques. To evaluate the PFD at a spatial resolutions of city/county units, the 20 representative evaluation indexing factors were carefully selected for the three categories such as damage target(FDT), damage potential(FDP) and prevention ability(FPA). The three flood vulnerability indices of FDT, FDP and FPA were applied for the 167 cities and counties in Korea for the pattern classification of potential flood damage. Potential Flood Damage(PFD) was classified by using grouping analysis, decision tree analysis, and cluster analysis, and characteristics of each type were analyzed. It is expected that the suggested PFD can be utilized as the useful flood vulnerability index for more rational and practical risk management plans against flood damage.

  • This study was conducted to provide basic data for the establishment school forests in order to utilize school forests as a place for environmental education through analyzing the planting status in elementary schools located in Changwon-city. School forests including meditation forest were the largest in Yongho elementary school (below e.s.) in meditation forest school and Dogye (e.s) in normal school. Jehwang (e.s.) and Sangnam (e.s.) showed the most abundant green area given for the management per member. The number of planting species and individuals in school forests differed greatly by elementary schools. There was also a difference in the number of planted species for establishment of meditation forest. There were no significant difference the concordance rate between the plants planted in the school forest and the plants mentioned in the textbook between meditation forest schools and normal schools. Index of ecological health averaged 3.2 for meditation forest schools and 2.4 for normal schools, which is the result of increase in green area and green rate due to the establishment of the meditation forest.

  • This study analyzes the recognition of commercial business men and employers who operate the commercial zone along the streets in the downtown area on the planting for the roadside green space forming the important frame of greening in the downtown among the open spaces. Through the analysis, this study attempts to get the basic data to suggest the recommendable directions in planting and managing the street trees in the downtown. The results of this study are summarized as described below. The street green spaces are very important in improving the environment of the downtown and their necessities are also very critical. It was found that the street trees were recognized as the critical factor to enhance the aesthetical values of the city, provide the green shades and purify the air. This study also identified that the street trees have the positive impacts on the business environment rather than negative impacts. In maintaining the street green spaces, the most necessity is the service facility such as resting areas, toilets and garbage bins with the street trees. The commercial business men and employers who operate the businesses along the streets preferred the double layer type that the tall trees and green walls are planted together along the streets for the street planting. For securing the green shades in the city, the planting of linear green spaces such as streets and waterways is critical. Moreover, the street trees accounts for the important position in the urban open spaces. The majority of commercial business men and employers consider the participation of citizens for greening as the very essential factor.

  • The purpose of this paper is to classify zones disrupting green spaces in city and to evaluate of their grades. The results are as follows; L There were 158 green spaces in Dalsu-gu. The 158 green spaces were classified 4 patterns and minutely classified into 9 types. The area of the 'nature park' type was turned out to be $70.1\%$ of the total area of green spaces in Dalsu-gu, then the type was considered as a important part of the green-network in Dalsu-gu. The 9 types such as 'nature park', 'river', 'neighborhood park' and so on were analysed with ecological indexes. 2. Based on the ecological indexes of 'ratio of the green space', 'features of the surrounding matrix' and 'travel distance of the wildlives' , zones disrupting green spaces were ranging widely and re-divided to 236 sectors. 3. The analysis results for classifying the grades were that grade I appeared over industrial complex and housing complex widely. On the other side, grade II and III appeared around or between nature park and neighboring park Consequently, it was necessary to consider the grade and make zones disrupting green spaces into green space for improving green network.
