1- Introduction Nowadays identification of the process of land use change and its effective factors are considered as the important issues of urban planning. Among the factors influencing land use change, demographic factors are the most important and they are overshadowed by other factors. This research deals with the effects of migration on land use change in Islamshahr City, aiming at finding a clear and logical understanding of the dynamic and variable issues of Islamshahr City as one of the largest immigration cities. In this regard related literature was reviewed and the relevant theoretical principles were chosen. Factors influencing the change of land user were determined using the perspectives of theorists such as Chapin, McLoughlin (factors such as economic factors, government, urban physical development, communication and infrastructure, nuclei living, social and demographic factors). Dependency theory was also used to define the relationship between migration and land use changes. 2- Methodology The research methodology is descriptive and analytical the relevant data was collected through documents and field methods. The tools used in this research are ENVI and GIS software packages, aerial photographs and satellite images of Islamshahr City. To extract land use maps aerial photographs have been used in making handheld digital method after georeferencing operations and satellite images have also been used after geometric correction through maximum possible methods or maximum likelihood methods in ENVI Software. Kappa coefficient has been calculated to assess the accuracy of the extracted maps. To measure the equilibrium distribution of land use in the city has been used Williamson index and Coefficient of Variation. of presence of Siberia HIGH pressure and regional condactors are the most important of them. In this period, the main origin of winds are HIGH pressure on Caspian and after that cold weather on hendokosh and Himalaya`s height. In other words with become strong of HIGH pressure on Caspian sea , this factor as superior factor have played role and moving the air toward low pressure of southeast of Iran , then when it reaches to Sistan region, have north northwest direction and after passing from Sistan , have deviated toward southeast .
