Abstract

Various researches on assessing and mapping of DESERTIFICATION have been carried out which have lead in development of regional and local models. In this study the MEDALUS method have been applied to assess and map the current status of DESERTIFICATION in the SOFIKAM – MANGALI plain, the northwest of the GOLESTAN PROVINCE, Iran. The criteria and indices model were re-defined before the model application, whereas in the revised model 5 criteria, 20 indices were used to assess the condition of the study area. The criteria included were water erosion, vegetation, climate, soil and management. Then several sub-indicators affecting the quality of each main criterion were identified. Similar to the original version of the MEDALUS method, each sub-indicator was quantified according to its quality. ArcGIS 9 software was used to analyze and prepare the layers of quality maps using the geometric mean to integrate the individual sub-indicator maps. In turn the geometric mean of all five criteria quality maps was used to generate a DESERTIFICATION map of the study area. The results showed that 54.12 percent of the area is classified as severe, 43.7122 percent, moderate and 2.17 percent as low affected by DESERTIFICATION process. Further analysis indicated that the soil and vegetation indicators were the most important factors affecting DESERTIFICATION process in the SOFIKAM – MANGALI plain, the northwest of the GOLESTAN PROVINCE.
