Prediction of land use of Hexi Oasis based on Markov mode

Based on Markov model,this paper predicted the land use changes of Hexi oasis.The result showed that the area of cultivated land and grassland will decrease,and the area of forest land and garden land will increase from 2005 to 2010.In addition,the area of cultivated land will change into garden land,forest land and construction land from 2005 to 2010.The area of forest land changes most largely because the policy of converting cropland to forest or grass land is fulfilled.
