Abstract :

During recent decades, urban development process has increased because of the industrial revolution. This process has facilitated urban target immigration which considered to  be in priority comparing with urban – infrastructure construction. Such imbalance situation has made some problem for urban development. The Industrial development and other factors have affected in urban & rural structure. These factors have attracted the population to urban Centers. This circumstance can be seen in the metropolitan specifically. Alvand town enjoying such specifications during for last decades. This analysis using Shannon's & Heldren models to study the town's physical development targeting the improvement of physical pattern of Alvand town. The result indicate that Alvand town had developed unsystematically due to the lack of municipality and urban management entities up to 1361. This town has developed such way in spite of establishing municipality since 1362 to 1375. The speed of development has decreased comparing to previous decades since 1375. This situation has made Alvand "town's appearance different & ugly. These models have indicated that the rate of spiral could be 43%. However, there is a huge difference between Antropi value made by horizontal development and urban spiral during last decades. so the results show that it would be possible to suggest "Nosrat Abad" (13th Zone) as future development pattern of Alvand town. So urban construction would be in priority than urban – target immigration
