Abstract

The purpose of this study is to deliberate for human’s role in desertification. To achieve this purpose, we’ve used vegetation destruction and LAND MANAGEMENT criterion, which LAND MANAGEMENT criteria is including agriculture LAND MANAGEMENT, rangeland management, mineral LAND MANAGEMENT indices and vegetation destruction criteria is including plant cover percentage, range trend, resistance against drought and conservation against erosion indices. The data of each indicator imported to Arc GIS 9.3 after statistical analyzes and normality test with kolmogorov-smirnov method in SPSS15. These data interpolated with IDW and normal and discrete kriging methods to produce their maps. Methods with highest accuracy have been selected. Then, the maps scored between 100 in 200 by MEDALUS approach and final map of each criterion have been created from the geometric mean of its indicators. Finally current desertification status in Segzi plan of Isfahan has been created from the geometric mean of all six criteria. The results showed that the area of severe and very severe classes of desertification equaled to 74,169 and 37,998 hectares, respectively. The results also showed that VEGETATION COVER percentage and rangeland management are the most important indicators of classification in Segzi region of Isfahan.
