DETERMINING THE QUALITY INDEX OF VEGETATION COVER USING THE MEDALAS MODEL FOR THE REGIONS OF WESTERN IRAQ

Three sites were identified within the districts of Hit, Haditha and Anah from Anbar Governorate for purpose determining quality vegetation cover. The office work included obtaining topographical maps, Satellite imagery, digital elevation models, in addition to climatic data. course field was determined on basis geomorphological features terrestrial perspective nature ecosystem. A semi-detailed survey conducted based networking method areas Hit Anah, while free adopted area. Soil texture classes study ranged sandy loamy, clay loam, loam clay. And calcium carbonate content soils between 126- 495 g kg soil-1. As gypsum areas, it 68 - 480 organic matter varied 2.4-11.4 results showed that percentage plant coverage fourth class, as 27.88% 34.60% all areas. drought index which is described very dry, its values ​​are 5.31, 5.78 5.61 regions respectively. erosion guide are first class with low second moderate erosion. Vegetation (VQI) ​​were distributed medium
