Due to the vulnerability of Hyrcanian forests, maintaining and improving its management is of paramount importance. Therefore, considering the different types of management, the impact of management on the sites should be determined. In this study, landscape modeling and land use changes were performed in ENVI5.3 and Arcmap10.5 softwares. Hyrcanian forests are the most important natural resources and are now part of the world natural heritage. That’s why conservation and planning are so important for maintaining it. Land use changes and deforestation were modelled using satellite images from 1933 to 2016 were studied using landscape indices such as spots, density and continuity of 2026. The results showed a 10% degradation trend over the period. Deforestation is affected by the landscape. Maintaining a sensitive area like looking at the continuity and density of forests is a very important area. As it has been shown, the sustainability of forest areas is highly dependent on the size of the forest patch, and the development of roads increases the boundaries and margins along that patch size, eventually reducing congestion and increasing the scope for human aggression. Although the density and centrality of the forest have a low relationship with forest protection from degradation, it is observed that the spots with this low ratio have higher degradability, as the isolated patches experience greater vulnerability. Landscape is the most important factor in the destruction of forests in the North, especially if viewed on a mosaic scale.
