Nowadays, assessment of environmental impacts and potentials is considered as one of the most basic issues in economic, social, urban, and rural planning. Urumia Lake maximum area belongs to May and June and its least development occurs in September and October. Also, its total area is about 500 km. There is an internal flow of water in the west from the north to the south and in the East, it is from South to North, and in the southern coasts it moves in a west- east direction. This factor increases the problems of areas located on the east of the lake that have the maximum regression. Depending on type of its purpose, this study is applying and its nature and methodology are descriptive - analytical. First, the mosaic images of the years 1985 -2013 of Urmia Lake were applied within the software environment, its different parts were cut. Then, using ARC GIS different layers of population, residential areas, elevation, and land use were prepared by overlapping the 5th layer and making a suitable map. These were used to interpret each map. Researches showed that most cities located in the eastern part of the study area such as Tabriz, Azarshahr, Sufian, Miandoab and Marand at most risk and cities like Bonab in which the wind direction is toward the west are at top risk, too, because most regions along the lake are located at elevations below 30 m from the sea level. This factor increases the rate of risk in these areas. If salt displacement by wind and irrigation by farmers lead to salinity of irrigated land and dry-land with an area of about 10,000,000 hectare, these problems will be added over time, and ultimately, will lead to the emigration of hundreds of thousands of people in the area.
