خلاصة:
The expansion and growth of cities is a remarkable phenomenon in urban planning literature,
so that unpredictable developments have become more evident in recent decades, especially in cities that have undergone changes in their physical structure following the promotion of their political role. The present paper seeks to identify the factors driving growth in the developed areas of Ardebil city and extract basic factors and variables by investigating development of Ardebil. In this study, 27 variables have been tested in 920 expansion blocks during the years 1996 to 2011 using GIS and factor analysis. Four main groups including congestion factor, external factor,
access factor and facilities are identified as driving forces of growth. The final combination of four factors in the Arc GIS environment show that the north, east and south east blocks of Ardebil had a higher score than the other blocks; in other words, these factors have the most effect on the growth of these areas. In addition, the Southwest blocks with the lowest score of between 0 and 2 have had the least impact from among the factors mentioned.

"Investigating Urban Expansion and Its Drivers in Ardebil The expansion and growth of cities is a remarkable phenomenon in urban planning literature, so that unpredictable developments have become more evident in recent decades, especially in cities that have undergone changes in their physical structure following the promotion of their political role.
Social factors that can be included in urban growth models by simple indicators such as population density or racial fabrication and the average income of people and the third is economic factors that are often considered by accessible indicators such as distance from the city center, distance from the road network and distance from water resources; these variables can be considered as an alternative variable for job accessibility and employment.
Hasse (2002) describes more than ten factors of the causes of urban growth that can be considered as land use densities, mutated development, development of distinct and separate uses, inconsistent development with regional planning, strip development along highways, new road network efficiency, access to important social nodes, expansion to sensitive and protected open spaces, and more.
In this research, 943 urban blocks added to the city boundaries in recent decades are considered as matrix rows and 34 factors affecting the growth of Ardebil are considered as matrix columns forming the primary matrix of information.
