ارزیابی شدت خطر بیابان‌زایی در دشت جیرفت با تاکید بر معیارهای زمین‌شناسی و ژئومورفولوژی

Desertification asone of the most important of environmental threats in the present century,is one of the main obstacles to meeting the needs of the inhabitants of arid and semi-arid areas.better understanding of desertification severity and determining the most effective factors on it are the first steps to de-desertification. For this purpose, the severity of the Jiroft plain to desertification was investigated using IMDPA method on the basis of geological and geomorphological criteria. Firstly work unit map was created using geology, land use map, Landsat 8 satellite imagery and Google Earth data. In each unit the "slope", "land use" and "erodibility" indices scored and combined with each other by calculating geometric mean of indices, finally the map of desertification hazard was generated in GIS10.3 software.
The results of this study showed that Jiroft plain was classified in moderate class (II) of desertification hazard. Accordinglyalthoughin the Jiroft plain the geological and geomorphological factors have moderate intensity on desertification but it can be turning a risk to an environmental crisis by unsustainable use of lands and natural resources. According to findings, it can be concluded that the management strategies and landuse activities in Jiroft Plain needs to consider the spatial planning.Desertification asone of the most important of environmental threats in the present century,is one of the main obstacles to meeting the needs of the inhabitants of arid and semi-arid areas.better understanding of desertification severity and determining the most effective factors on it are the first steps to de-desertification.
