Abstract
ABSTRACT In this research, desertification hazard has been analyzed by resilience range overeastern north of Iran. In this research was assumed that resilience of ecosystem refers toinherent properties of ecosystem. Soil erodibility, rainfall erosivity, topography and landcover- a reflection of land-use management- are assumed as representative factors ofresilience range in this study. In order to calculate resilience range an integrated mapwas developed based on the combination of erodibility, erosivity and slope factors.Ultimately desertification vulnerability was estimated by multiplying resilience range andland cover into resultant maps. Results indicated that about 44% of study area is fragileecosystems with high desertification vulnerability. Also the results showed that vegetationcover has main role to increase resilience potential of ecosystem to responseperturbations.Keywords: Resilience; desertification vulnerability; erodibility; Khorasan Razavi.Original Research Article
