Knowing the quantitative and qualitative characteristics of changes in environmental planning, land preparation and sustainable development are very important.Currently, the use of vegetation maps is one of the important elements in generating information for macro and micro planning. In this research, data from the Landsat satellite bands of ETM and OLI sensors have been used to show the temporal and spatial changes of Behbahan city's vegetation cover. During the examined time periods in 1998, the vegetation cover was 1294.38 and the areas without vegetation cover was 7.46371, which indicates that human intervention in these areas was very little, but the vegetation cover in 2020,4 It was 1189.1189 and the areas without vegetation was 112.472.Areas with vegetation cover were 12.94% in 1998 and about 11% in 2020. The ratio of vegetation cover in 1998 increased by 1.05% compared to 2020 and is decreasing in 2020. Areas without vegetation cover In 1998, the amount of the area was 0.07%, but in 2020, the areas without vegetation cover reached 1.12%, which means that the areas without vegetation cover are increasing in 2020, and the reason for this change in population growth is excessive construction. Also, the illegality of land use changes, which play a significant role in the reduction of vegetation and global warming, which are among the factors. Also, the lack of respect for the balance of livestock and pastures and excessive exploitation in many pastures of Iran, cause the destruction of these resources. and caused irreparable damage to vegetation and soil.
