Abstract
Off-road activity has increased significantly in different environments, especially arid regions and desert environments of the world, which can have negative effects on the ecosystem and different levels of desert landforms. This study is based on a qualitative, descriptive-analytical and quantitative method that examines and monitors the trampling of landforms in desert areas and emphasises the need to protect the Lut Desert as a unique natural and cultural heritage against anthropogenic factors. This study was conducted at two levels. In the first level, the effects of off-road were studied and monitored in different years, and in the second level, the region wind and its relationship to the persistence of off-road effects on the land of desert forms were analyzed. This study was conducted in the northwestern region of Shahdad clots to Shoor river at a distance of three thousand meters from Shahdad-Nehbandan road. First, Aphrodite works were obtained in digital satellite images and then the density of Aphrodite works was obtained at certain intervals and compared on both sides of the road. During different years, these digitized works were examined and monitored. Based on the obtained results, it was found that the density of off-road effects has an increasing trend and shows that in recent years, off-road riding in the Lut desert has attracted more tourists. At a distance of three thousand meters from the road, the density of off-road effects is about 14%. And at a distance of two thousand meters 6%. And at a distance of three thousand meters 01%. The result shows that there is a direct relationship between the distance from the road and the off-road density.
