Expansion of cities on the fringes has caused the loss of natural landscapes, agricultural lands and environmental problems. Restoring and improving these effects based on the principles of environmental design is a necessary matter. Considering the current state of development of Arak city on the eastern edge, it is very important to pay attention to this part due to the value of high-quality soil, the existence of rural areas, gardens and agricultural lands. In this paper, a part of the eastern fringe of Arak was studied by satellite data and remote sensing-based ecological Index (RSEI) that includes four sub-indices: built-up area, vegetation cover, land surface temperature and land surface moisture. Integrating them was done by principal component analysis. The results showed that the lower ecological quality in different areas was caused by the development of infrastructures, impervious urban surfaces, industrial lands and in general the spaces resulting from the pressure of human activities and the ecological quality was higher in gardens, active rural agricultural lands and scattered parks and green spaces. Then, the results were analyzed in the pressure-state-response framework, and a part of the land named "Qanat Naseri" was redesigned in order to maintain and expand the existing ecological values based on the results and analysis.

Findings of this study show that most immigrant's ages and activities with their family members have migrated to Sabzevar. In terms of job status before migration, such as jobs with workers, farmers and etc are the important factor activity after labor immigration increases. In assets immigrants increased considerably among immigrant families view and income level of the migration increased so that less than one million Rails per month (in 2006) before immigration 69.2 percent of immigrants are included are, after migration only 32.8 percent of them are included. Regard to the results, control solutions, including population growth and increasing employment, and local people forming organizations, New nuclei population in the metropolitan area, recognition of property and housing and etc, in order to promote social and economic status of immigrants has been proposed.
