Yilmaz, H. Murat, Selcuk Reis and Mustafa Atasoy
This paper presents an integrated study of urbanization trends in Aksaray City of Turkey based on Geographical Information Systems (GIS) and remote sensing tools. The study explores the temporal and spatial characteristics of urban expansion and land use/cover change (LCLU) between 1987 and 2001. The administrative status of Aksaray was changed from district to province in 1989. Therefore, the study of urban expansion for Aksaray covers two different period of time during which the status of the city was different. The changes of land use/land cover in the city are spatially analyzed for these time periods. As the result of analyses, it has been determined that after the status of the city was changed to province, there has been 410 % of increase in the number of buildings especially in the urbanized regions, in 16 years between 1984-2000, as a result of the parceling. During this time period, the maximum increase in neighbor provinces of Aksaray is 120 %. This indicates that Aksaray gained a great development potential after its status was changed to province. This study also projected LCLU change using supervised classification for the next 14 years. The relationships of urbanization-landscape change and urbanization-population growth are also observed. For Aksaray, substantial LCLU changes were detected for the time period of 1987 - 2001. The LCLU conversion relationship implies that these changes are caused and leaded by urban expansion that produces a driving force for land use changes resulting in a higher return. The major factors influencing urban expansion and LCLU change are also discussed. Overall major factors influencing the urban expansion are detected to be the population, traffic conditions, industrialization, and politics.
