Since the process of increasing urbanization and its effects, has been made more important the necessity of planned about urban development. Some of the problems about this that we face are: metropolises issues, decreasing the quality of life due to more density of population and activities, new towns strategy buildings - especially in the middle of latest centaury - Thus, this model has been used in many countries (in past decades) and also it has been started since 1357 with the aim of housing for industry workers, and after the Islamic Revolution, mainly to absorb the metropolis crowd overflow.
Now, after more than one-fourth century and beginning of attracting population process for some of new towns, the main purpose of the article is the answer to this question, that "how much this policy was successful?". And we compare the performance of Sahand new town about the absorption of Tabriz metropolis crowd overflow with prior goals that are based on documental and survey methods on sample include 350 household, production and servicing units.
Findings show that, Sahand new town was clearly retarded of contingency planning about buildings, especially population absorption and employment. But the predicted performances to attract the overflow crowd of Tabriz and provide house, some deal orientation resolved to realize the goals.

Nowadays rapid development of urbanization, population growth, industrialization, unorganized transport system and urban traffic and green space shortage have caused increase of air pollution concentration in cities, especially in large cities. Therefore, attention into air pollution and factors and causes of increased pollutant concentrations are very important. Hence the purpose of this paper is to identity the effective factors on air pollution at Namaz Square station in Tabriz city.
Therefore, through of component analysis method, main components were determined in each season of year and by the application of multivariate regression model, main factors were defined. Results show that climatic factors (such as temperature, wind speed and direction) human factors (such as crowded population, green space shortage, high traffic, unsuitable roads) have the highest influence in the air pollution. Special attention therefore, to human factors can cause to the decrease of air pollution in urban central area
