Investigation of land use changes in hydrological units of Kavir-dar-Anjir watershed

Today, to prepare land use maps, using Satellite data and quantitative methods in remote sensing science is very common. Researchers and scientists of this science have used it widely in the two past decades. In this research, land use changes in hydrological units of Kavir-dar-Anjir watershed were evaluated by using supervised classification methods. The results show that the most proportion land use in 1987 is related to Meadow land in Hydrologic Unit Number 1 and the most proportion of land use in 2013 is related to Land with rocky substrate in Hydrologic Unit Number 1. Also the least proportion of land use in 1987 in all of the hydrological units is related to forest land in Hydrologic Unit Number 2 and the least proportion of land use in 2013 is related to meadow land in Hydrological unit number 8.
