Land use changes by using RS and Markov chain technique in the south-west of Tehran

Land use changes investigation requires the use of rapid methods and new techniques, respectively. The use of remote sensing and GIS and integrating them with accurate information and field data prepared multipurpose decision. In this study, used images of Landsat 2, sensor MSS June 1975, Landsat 7, ETM 2002, and Landsat 8 sensor OLI June 2013, from USGS site for developing maps and survey land use changes over the period of 38 years in ENVI and ERDAS software. The Landsat 5, TM sensor image, June 1991, used to prepare land use maps and compared with 2002 and 2013, to predict land use change in 2024. Results related to land use changes in the past 38 years show a reduction of 12% (9/7060 hectare) orchard area and an increase of 7% and 5% of residential areas and agricultural lands, respectively. Also the predicted land use changes in 2024 represents a decrease of 2% compared to the current state of the orchard, while the almost constant level of agricultural land, and residential area will increase 2 percent.
