  Introduction: Particulate matter enters the atmosphere mainly from arid and semi-arid regions where annual precipitation is very low and a large amount of alluvial sediments have accumulated over long periods of time. In fact, deserts and dried up lakes that have turned into small deserts due to climate change can be considered dust production centers. Iraq is one of the countries that is often affected by dust storms. The purpose of this research is to track, zone and identify dust centers in the border provinces of Iraq and Iran in a ten-year period. Materials and Methods: In order to carry out this research, a 60 km wide area along the Iran-Iraq common border was selected from Maysan and Wasit provinces located in Iraq (about 300 km along the common border). After performing pre-processing on the images (atmospheric and radiometric corrections) using the relevant algorithms, high errors and then using the normalized vegetation index (NDVI) to classify the earth surface phenomena, separately based on the threshold values of these Indexes were categorized. Results and Discussion: Spatial distribution includes three classes a) water areas which are related to areas covered with water, rivers, marshes and wetlands b) bare soil which includes areas without vegetation such as stony areas, uncultivated agricultural lands Sand fields and sand fields and c) Vegetation which includes areas covered with forests, pastures and agricultural lands were categorized and finally the areas prone to dust generation were determined and their area was determined Conclusion: Be made In general, the results of this study with other similar studies in the countries of Iran, Iraq and Saudi Arabia show the effects of drought and the expansion of desert lands and the drying of wetlands, marshes and rivers and the loss of vegetation and the bareness of the land without any cover. It is pasture, forest and agriculture. Due to the large area of deserts, they can be considered the center of growth and zoning of dust storms, and to deal with dust storms, methods such as moistening the soil, biological and mechanical methods such as mulching are performed.
