Abstract: 
Today remote sensing has special place in national resources and vegetation studies. In this research vegetation and land use changes in margin of Damghan playa was studied. In this site, sand dune stabilization with use of Haloxylon plant has been done. Using MSS and ETM of 1977 and 2000, positions of sand dune in study site were detected and vegetation on sand dune with help of image processing techniques such as NDVI index alongsid with visual interpretation and field check was studied. Land use of sand dune surrounding areas and groundwater quantities were studied. The results show increase of vegetation on sand dune about 160 hectares, and increase of cultivated lands around of sand dune about 2067 hectares during the studies. Also, the results of ground water show about 45 cm annual decrease. Therefore sand dune stabilization, increase of ground water extraction and cultivated land increase, occasionally cause to increase of economical condition in study site, but decrease of ground water level cause salinization and critical decrease water wells.
