الملخص EN

The research aims to study the effect of topography (altitude and slope) on the density of vegetation in Koizah mountain range located in the province of Sulaymaniyah in the northeast of Iraq within the Kurdistan region of Iraq, as area of (70.9 km2).

Through research have been identified the physical characteristics (rocky and tectonic region, climate, soil, vegetation) as well as identify the spatial distribution of each of these characteristics.

Through research have been identified the topography of the area (altitude and slope), where the record altitude ((1,227.2 - 1027.9) above the sea level and it is the highest prevalence topographers percentage (29.38%) of the total area of the mountain range and the highest prevalence of topographers to slope according to the classification of Zink fragmented cut type as a percentage of ((48.69%)) of the total area of the mountain range also by the research has been classified vegetation, depending on the value of normalized differences vegetation index (NDVI) to three types and the severe type plant density cover more than half of the mountain range area, As well as determine the area of cultivated land, which reach to (11.9 km2) and areas of natural vegetation are (55.55 km2).

The results showed that vegetation intensity of severe type affected by to altitude, And that the relationship between the altitude and vegetation intensity (severe type)are negatively high , while the relationship between the vegetation intensity (medium and the little classification )are positive and a weak-to-moderate.

Finally the search shows that the vegetation intensity (all types calcification) affected by the degree of gradient and the relationship between them are a very strong negatively relationship.
