abstract = {Dust is an event that occurs in most sections of the world that leads to financial loss and harmful environmental impacts. Several factors are included in dust event incidence, some of them are natural and others are due to human processes and their impact on the environment. Thus, very critical situations are coming and it is expected that the majority of urban and rural populations will migrate to the rest of the country, especially from western and southwestern regions leading the way to a lot of economic damage. Studies conducted in the country showed that the western regions of the country are more exposed to dust systems due to their geographical and climatic location and the proximity to the deserts of neighboring countries such as Iraq, Syria and Saudi Arabia, especially since most of the atmospheric system of the North West, West and Southwest are imported into the country. For this purpose, investigating, studying and recognizing physical and chemical composition of dust and soil resulting from it to determine and identify harmful elements and ultimately policy-making and planning for its elimination as regional alliances in the field of policy-making and foreign co-operation vital. According to the obtained results, it was found that the dust in spring of 2015 in Zahedan city has spatial and temporal changes. The spatial and temporal changes in dust can be caused due to the low green space, especially in the direction of wind blowing, developmental activities and 120-day winds of Sistan and the difference in urban density and urban marginal topographic complications. According to zoning map in the spring of 2015, the existence of an inconsistency in the dust spatial variations in the spring indicated that spring is the source of dust in the city. Since part of this amount is due to the drying of Hamoon Lake, wind erosion control measures in these areas can be effective in reducing the loss of dust in the city of Zahedan. In Iran, the use of geographical information systems and remote sensing to monitor natural hazards is increasing. Hence, the attention of managers of various fields of natural resources and environment to the capabilities of this software and attention to the researches have done in this regard sound necessary and useful. The results of many studies in the country showed that the frequency of dusty days is increasing.},
