Due to the conservation value of the Sorkhabad Protected Area, the uses within and around the area have direct and indirect effects and consequences. Appropriate management plans should be developed for the area by reviewing changes to these applications. Land sat satellites from the 1987 and 1997 time periods were prepared and used to investigate quantitative and qualitative changes in the region's ecosystem and environmental management. In this regard, after applying geometric and spatial corrections and performing image optimization, the maximum likelihood of similarity changes was evaluated and compared using unobserved classification and supervised classification methods , The accuracy of the produced maps was calculated and calculated with 90.69 and 97.47 overall accuracy test and Kappa index 0.88 and 0.96 respectively. The results showed that for 10 years agricultural and forestry use has grown well and rangelands, orchards and bare soil have declined. According to satellite imagery, vegetation status is probably better than before.
