Abstract

Remote sensing has been considered as an appropriate tool for temporal monitoring of some natural phenomena. ARDESTAN Region is prone to LAND DEGRADATION and masked by sand sheets, sand dunes, clay flats, desert pavement and different kinds of salt crust due to dry climate. To study the trends of LAND DEGRADATION in last three decades, four satellite data sets of LANDSAT MSS, LANDSAT TM, LANDSAT ETM+ + and IRS acquired in 1976, 1990, 2001 and 2008, respectively were analyzed. The time series analysis revealed that the bare clayflats have decreased and clayflats with vegetation cover have expanded over 32 years. During this period, the areas which are covered by gravel have decreased 13 percent and both the area covered by salt crusts and aeolians have extended 2 percent. Puffy grounds have developed by 2001 but their magnitudes have decreased between 2001 and 2008 as they have been masked by the moving sand ripples. Reduction of 13 percent of sand sheets between 1990 and 2008 indicates that soil conservation practices have efficiently controlled LAND DEGRADATION and desertification in the area.
