Analysis Of The Relationship of Vegetation Cover Changes to Topographical Factors in the Qadmous Region

Abstract

The research dealt with the study of the effect of topographical factors on the changes of vegetation cover in the Qadmous region during the period (2000-2020) Using the Normalized difference vegetation index and satellite images Landsat 7, Landsat 8 with a spatial resolution of 30 m. In addition to land use maps of the study area,  Using the stepwise multiple linear regression. The research found that the correlation between the NDVI values above sea level heights in the Qadmous region is a strong inverse relationship R=(0.77) with a significant value, Whereas the highest elevation areas correspond to the lowest values of NDVI. Also,the correlation between forest cover and height is a strong inverse relationship, due to the forest cover encroachment in the high elevation areas.The degree of slope and aspect did not affect the NDVI values as the correlation between them is not statistically significant, this is due to overcoming steep slopes into terraces and planting them fruit trees.
