In recent decades, cities have grown without any program and urban areas became several times larger than their original size in a short time or their development occurred in separated parts without planning. This problem is known as urban land spread pattern and along with this pattern of urban development, agricultural land use changed. Hadishahr city is one of the cities of East Azarbaijan province, located in central city julfa, link other cities during the last decade, had an imbalanced and spread development, and this growth caused adverse environmental effects such as loss of good agricultural land. The purpose of this research is primarily, understand the pattern of development and physical development of the city and after that; explain the environmental consequences of physical development. To achieve this study used spatial statistical tools in Hot Spot Analysis, to analyze hadishahr`s physical expansion and then understand the environmental consequences of physical development on the type and extent of change and in continue, to understand the environmental consequence of physical separation and also the changes types and extend of changes in the usage of agricultural lands and green spaces. Due to physical spread of the city, we used two- image analyzer, OLI and TM, of Landsat satellite 5 and 8 during the year 1998- 2009.The results suggest that the pattern of physical development of the city has been sprawl over 15 years. In this pattern of scattered development, agriculture lands and gardens have the greatest change about 62% which about 48% of that changed in to urban usage and 14.5% converted into wasteland. Due to adverse consequences of the development of distributed spread and achieve stable development and urban form, the compact city model is proposed as a model for future development.
