Qerqan Oasis—a typical Oasis in arid area was chosen as an example,the remote sensing images of MSS in 1973,TM in 1991,ETM+ in 2001 and 2008 were used as major data sources,be combined with fieldwork data,the appropriate disaggregated indicators system was selected to classify the images,and classified the images,and then obtained the different types of land use/cover transition matrix.The results showed that the cultivated area had been showing an increasing trend in the last 35 years,it was increased 105.32 km2,the increase of the cultivated land is mainly from the conversion of grassland and woodland,the cultivated land is the fastest growing land use type.Woodland and grassland had been gradually decreasing trend,and most reduced land type was the forest land,it was decreased 69.459 km2.This was mainly caused by the conversion proportion area of woodland to the grassland、water land and cultivated land was much faster than grass land conversion to the forestland.Grass land decreased 63.093 km2,and it was mainly from the conversion of grass land to the cultivated land and rare land.The water area had been showing an increasing trend,it is increased 22.073 km2,and the increase of water land was mainly from the conversion of grass land and rare land to the water land.Rare land had a little increasing trend,and it was increased 5.093 km2.
