Assessment of Physical development of Damghan city based on techniques of Degree of Aggregation, the Coefficient of Gini and the Coefficient of Entropy

In the recent decades, physical development and population growth of cites of Iran has been very rapid and accelerating, so that the growth of cities as a problem or issue and necessity of attention to urban issues, particularly its structural issues in scientific framework have been important and necessary. In this direction, the present study through descriptive –analytical method aims to evaluate physical development of cities in order to provide analytical data on various aspects of physical development and growth,the nature of the problems and its consequences. In this research, Damghan city is examined as a case study. population of the city Within 55 years has increased more than 6 times and its area has a growth of more than 15 times. Data collected by documentary and field methods, have been analyzed using the techniques of Degree of Aggregation, the Coefficient of Gini and the Coefficient of Entropy. The result obtained from the study of physical development of the cityindicates that as we close to year 2011, the development of the city has intended to the horizontal distribution and dispersion.
