Abstract

After desertification mapping for proper management is very important to recognize the similar work units. Because, the two geomorphological units or two work units that have the same desertification intensity classes, do not necessarily require the same management. In this study, to identify the similar work units that need the same management, at first the intensity of desertification was evaluated according to 4 important criteria in the region (climate, soil, vegetation, and wind erosion) based on the IMDPA model and then classified and identified the similar work units using Cluster analysis method. The results of desertification intensity based on the IMDPA model showed that there are two classes of extreme and medium with the areas about 59.32 and 40.68 percent respectively. This is while the results of cluster analysis showed that all geomorphological units are classified in six different clusters. According to the results, two work units with the same desertification intensity are not necessarily in the same cluster, and work units with the same intensity are in different clusters. Therefore it can be said using the clustering method with desertification models to identify similar units for planning and implementation of management programs will have well efficiency.
