Spatial analysis physical Karaj city with an emphasis on Smart city growth indices

Spatial development - physical, uncontrolled urban growth and urbanization resulting in Karaj during 1335 to 1390 the population of 14,526 people in 1335 and about 2km square area of about 180km ² and a population of about 1,614,626 people become.The spatial development accelerated due Branch ecological resources, including agricultural land and industrial mineral soils, surface and underground water resources is heavily exploited. Rapid displacement of population, expansion of urban Aspral change uncontrolled agricultural lands and natural resources, uneven development, application, and subsequent social and economic anomalies, including issues arising from the development of urban space - the physical city is Karaj. The purpose of this study is to explain the process of spatial analysis of these issues. This research method is descriptive - analytical models using Shannon's entropy and Holdern and smart growth urban metropolis, Karaj during 1335 to 1390 has been analyzed. The results indicate that Shhrkrj from 1335 to 1390 the growth has been unevenly distributed in a separate core. Karaj growth pattern from 1375 onwards, growth has been rapid and Aspral. In 1385 the highest growth rate Aspral 24 percent. The density of people per hectare since 1375 to 1385, that figure dropped to 09/94 persons per hectare in 1375 to 52/76 persons per hectare represents an extension of the city limits. These statistics reflect the destruction of much of the best agricultural land in the surrounding.metropolitan.Tehran.
