his study aims to forecast the growth of the Seoul Metropolitan Area in order to reasonable manage the area which may result in deteriorating damage of natural environment and experiencing rapid development. Also, the study aims to analyze the change of land demand by scenario with Land Suitability Assessment. Based on reviewing of earlier studies, this study analyzes existing urban growth predictionand Land Suitability Assessment. As a result, earlier studies about urban growth predictionmainly performed macroscopic analysis. It did not consider social and economic condition and decision making of developing body.Also, earlier studies about Land Suitability Assessment only pointed out problem of existing Land Suitability Assessment. This did not make a reasonable alternative for urban growth prediction. For this reason, this study presents application method of Land Suitability Assessment by microscopic land demand forecast. In order to apply microscopic land demand forecast, this study uses Raster map by land use considered density using AIS (Architectural Information System) and KLIS (Korea Land Information System). Then, the study uses the raster map asa dependent variable which explains the change of land use. Also, as independent variables, it sets up distance, physical, economic, and institutional factor which are influenced on land use, and using these factors and Multi-nominal Logit Model, it calculates the probability of land use change. In addition, this study divides the Seoul Metropolitan Area into management region in order to apply Land Suitability Assessment, and also, the study uses not existing parcel unit but raster unit because of connection with land demand forecast. It divides the management region of the Seoul Metropolitan Area into a prior development area, prior preservation area, and I-V grade area. Also, this study estimates urban growth by scenario through land demand forecast and Land Suitability Assessment constructed by raster unit. The scenario is formed in 4 types of situation by development type and the grade of Land Suitability Assessment. As a result of analysis the scenario focused on the Seoul Metropolitan Area, the result is that land will be developed on 144㎢-413 ㎢ until 2025, and that management region of the Seoul Metropolitan Area will be developed on about 856㎢ in 4 and 5 grade area. This means that although land demand in the whole area of the Seoul Metropolitan Area may be controlledon planned management region by 2025, land demand in local area needs to readjust the grade forplanned management region. The significance of the study is to use land demand forecast and Land Suitability Assessment for growth management, and through the method constructed, it is possible to verify that a reasonable Land Suitability Assessment is realized. However, it did not consider redevelopment because of the limit of data and only reflected land demand of urban growth. Therefore, further study needs to consider various studies such as demand forecast and supply plan of traffic facility, environment impact assessment, and spatial distribution of future housing demand. Such further research is expected for a reasonable decision making of policy makers.
