Preparing a map of the sensitivity of the lands of Ilam province to dust production using data mining models

The phenomenon of dust is one of the most important environmental crises in arid and semi-arid regions of the world, which has harmful effects on human health and the environment.Dust or fine dust refers to very small and light particles of silt, clay or sand, which are moved and transported for a long distance in the earth's atmosphere as a result of wind erosion and desertification by the wind, and the horizontal visibility is between It is limited to 1 to 2 km or less.Due to being located in the dry and semi-arid belt of the world, Iran is exposed to numerous local and extra-regional dust systems.The dust storm in our country during the last few years has involved the provinces of the country as a serious crisis and has brought dangerous consequences for the residents of these areas in terms of environment, health and economy.Identifying the dust source area using remote sensing techniques is one of the most important methods in the world.The purpose of this research is to identify the centers of dust harvesting and its risk zoning using RF and MARS models.It is in Ilam province.38 dust harvesting centers were identified in the study area.70% of the identified foci were used for modeling and 30% for evaluation.Then 7 factors including soil, lithology, slope, vegetation cover index (NDVI), distance from the river, climatic units and land use were prepared as independent and effective variables on the center of dust collection.Then, using RF and MARS models, dust risk zoning maps were prepared.
