| Abstract: | On the basis of TM image interpretation,this study was to monitor the dynamic change of land desertification with an area of 8 355.20 km2 in Minin Oasis and its peripheral areas during the period from 2003 to 2008.The results show that land desertification was serious and its area accounted for more than 80% of the monitored area.The desertification land in Minqin Oasis was divided into two types,i.e.the wind-eroded desertification and salinized desertification,and it was distributed in the oasis and its pe... |
