      This study focused on the probability modeling of the land use change for a sustainable city and the development of a sustainable city by assessing the sensitivity of the forest environment. The environmentally sensitive areas were systematically estimated using the landscape ecological index and NDVI. This study examined the pattern of city growth and the structural change of the landscape ecology by combining recent remote sensing and GIS techniques. The summary of key findings is as follows: First, to assess the forest environment, a structurally fragmented area was assessed using landscape ecological indexes that estimated the landscape structure principles. NDVI was used for the analysis of the biodiversity and determination of preservation value. The analysis result showed that the area of the forest in Chon-Aan City is expected to decrease continuously, that the connectivity of the forest patches would be weakened, and that formality and complexity would increase. These results suggested that the forest as a natural resource has been seriously damaged after creating the urban-rural consolidated city for the past 3 years since 1996. The deterioration of plant vitality as well as the quantitative decrease caused the increase of pressure from the environment. Second, to explore the effects on the probability of being remained as a forest, the landscape ecological index and NDVI were analyzed. The forest environmental sensitivity index was calculated using the result. The ranked forest environmental sensitivity index was used to analyze the  environmental sensitivity of the forest for each region. Out of 30 variables in landscape ecological index and NDVI, five variables excluding variables in correlations and multi-collinearity were used as independent variables, and the probability of remaining as a forest was used as dependent variables in conducting a multi-regression analysis. After setting weights of the five indices using a standardized regression co-efficient, sensitivity index was calculated and ranked into five levels. Based on these results, the mechanism of land use change in each region would be understood and the land use management policy would be developed in each region. If environmentally sensitive forest  areas are selected, it would be useful for regional management and decision making. 김훈희, 이진희 국토계획

      This study was attempted to explore the effects of land use change on the basis of the national land use plan management practiced in Korea and abroad. To this end, the probability modeling of the land use change for a sustainable city was developed using the multi-nominal logit analysis and the change of forest area was produced by application of the projected population in 2016 Chon-An city plan. This study also explored the positive and the negative aspects of the development using by the time series analysis for the land cover and the cross-sectional approach. The summary of key findings is as follows : First, the analysis of trend and pattern of city spread in Chon-An city using five Landsat TM remote sensing sources (1985, 1987, 1993, 1996 and 1999) showed that while developments were passive from 1985 through 1993, they became active from 1993 to 1999. It also showed a trend of small-scale forest first changing into agricultural land or vacant lot and again turning into urban area over time. As for the direction of city expansion, urban area was spreading out to the northern part of Chon-An city including Sung-Hwan Eub, Ip-Chang Myun, and Sung-Keo Eub. Second, a multi-nominal logit model was developed to explore how social, economic, and environmental factors had effects on the land cover. The model set elevation, slope, population density, land estimate, road accessibility, and city accessibility as independent variables and changes between land covers as a dependent variable to understand the impact on land cover changes. This city was analyzed by segmenting Chon-An city into grid cells of 30 × 30m. The analysis showed that land cover with higher elevation and slope, lower population density and land estimate, and distant from the road and the city showed a higher probability of being remained as the forest. By comparing the probabilities of being remained as the forest in 1996(0.720) vs. 1999(0.758), the level of damage in the forest had increased in 1999 than in 1996. This analysis showed that the forest preservation is declining sharply in central living areas. In case of Du-jeong living area, the population is expected to rise four times in 2016 by compared to 1999 and the level of forest preservation is likely to decrease(probability=0.86). Finally, using remote sensing and GIS in the analysis allowed to process a large amount of spacious data. The result of this study may be applied to the spacious modeling and define the quantitative changes in resources and spacious characteristics. These results, therefore, can be used as a means of policy assessment and the decision-making, and can be helpful in forecasting urban changes in the future. 김훈희, 이진희 국토계획
