تقييم تدهور أراضي مشروع الميمونة في محافظة ميسان باستخدام تقانات اتخاذ القرار المتعدد المعايير

Abstract EN

The Mymona Project was chosen within the Mesopotamian plain in Misan city, with an area of 657 km2, due to the variations of geomorphological and physiographical features as well as significant variations in soil conditions led to occurring multiple geological and pedological processes led to degrade the lands of this project.

Thus, the site was chosen to achieve the objectives of this study, which included the determination of land degradation, used criteria and indicators according to the requirements and their relevant to for environmental conditions of the study area.

Data of Sentenil_2 in 26/4/2018 were downloaded from United States Geological Survey (USGS), the coordinate of the site of study area was (46º 45' 0.0"-47º 0' 0.0").

East (31º 45' 0"-31º 30 0") North.

The necessary improvement had been made as Image processing, atmospheric correction, mosaic were conducted.

Previous soil survey report, information and field data and the updated field data, soil sampling from pedons locations were used.

The data on the status of soil degradation that collected from image of Remote Sensing and field work was incorporated in matrix tables.

The results of degradation which determined by TOPSIS and AHP method are degraded by different degrees including: (Very high degraded, high degraded, moderately degraded, and non or slightly degraded) which occupying 75% , 2% , 4% and 19% .

These results are due to the effect of very low human activities to use land for agricultural activities as well as to the effect of bad management to the land and water resource in study area.
