شناسایی و پایش منابع گرد و غبار استان آذربایجان شرقی، مطالعه موردی: قوم تپه-نظرلو

Identifying dust production areas is the first step to deal with this phenomenon. In this study, the center of dust and fine dust in East Azarbaijan province has been identified and investigated, and the characteristics of the land have been introduced. Identifying areas, determining general characteristics, measuring and monitoring dust and determining the main and sensitive areas of fine dust production in East Azarbaijan Province were the stages of this study. This province has various sand dunes in the province that can potentially become a center of dust production. The most sensitive area to wind erosion is 2053.7 hectares in Aghaqomi (Nazarlu) and Qom Tepe centers. The share of land uses in micro-districts of the province is 48.8% of agricultural lands, 19% of dried wetlands or lakes, 32.2% of degraded pastures, etc. From the point of view of morphology, micro-rounded centers of the province are about 2.53% of hilly plains and 97.47% of flood plains, etc. The micropowder production centers of Qom Tepe is one of the most active centers in the province, which causes many problems for local residents and neighboring areas. This fine dust center mainly includes rainfed agricultural lands, abandoned agricultural lands, and dried wetland lands. At the level of the province, some lands such as plowed agricultural lands, abandoned wetlands, poor pastures, caused by water regression, etc., in case of adverse climatic factors and other environmental conditions, can potentially act as sources of fine dust production.
