Metropolises are horizontally drawn to the periphery due to the extreme concentration of power, capital and population and this physical development often occurs unevenly, which causes many problems including land use change, natural and socioeconomic transformation, and consequently environmental problems. Factors such as urban growth, land value and development density are among the most important factors in the formation of urban sprawl, which transforms the inner structure of cities and causes the heterogeneous development of urban indicators in periphery, and it transforms the areas into unplanned spaces. In this research, urban sprawl patterns and analysis of changes were carried out during three periods, using GIS and remote sensing, as well as Landsat TM satellite data and images of 1986 and ETM+ 2000 and ETM+ 2014. The findings of this research show that in the past three years, residential construction has increased dramatically in the region. The area of such construction rose from 4.89% in 1986 to 10.3% in 2014. In contrast, the area of agricultural land decreased from 61.33% in 1986 to 44.7% in 2014. Moreover, scattered structures and urban sprawl in the studied area were according to discrete sprawl pattern, which has led to inconsistencies in the agricultural sector and rural economy of the area. Furthermore, the expansion of the network of roads, highways, electricity networks and non-residential construction have exacerbated the discontinuous urban sprawl in the study area. On this basis, attention to the integrated land use planning alongside urban and rural integrated planning might be a remedy to reduce agricultural instability and to change the use of valuable agricultural lands and rangeland
