Abstract
The excessive increase of cities and their uneven growth due to natural population growth and excessive migrations is one of the fundamental problems of our country's urban network. Cities grow differently, including internal or endogenous development, connected or continuous urban development, and detached urban development. However, the issue of importance is how physical growth and development are formed and the extent and manner of expansion of cities, which has brought various economic-social and primarily environmental consequences. The purpose of this research is to investigate and analyze the factors affecting the physical development of Piranshahr City and its environmental consequences for the future development of the city and to control and guide its determining factors and forces. To analyze the data from factor analysis methods, multivariate regression analysis (using SPSS software), as well as the use of Landsat 8 satellite images and the Crosstab model in the years 1365 to 1395 in two fifteen-year periods for the city of Piranshahr, and with The use of satellite image processing techniques and geographic information system have been evaluated and analyzed. The results of this article showed that the built area of Piranshahr city has increased from 144 hectares in 1365 to 958.77 hectares in 1395, which indicates a physical expansion of 6.5 times for this city, which is the result of population increase (natural growth - migration) and change of land use (agriculture, orchards, barren lands) to urban built lands.
