In order to study land use and cover change (LUCC) and their driving forces in Qiemo Oasis in Xinjiang dry region, authors did the field investigation by using remote sensing of JERS-1 OVN data (1993) and LANDSAT-7 ETM+ data(1999).From 1993 to 1999 only six years past the LUCC was remarkable. The area of arable land and woodland had increased but the grassland and wetland decreased, meanwhile, the desert area increased. The driving force is clear. The policy of government decision is the general direction of LUCC. Population growth and economic interests of inhabitants are direct driving forces, which resulted a lot of arable land was reclaimed from grassland. In order to prevent oasis and arable land to be not hit by the desertification large-scale tree planting and afforestation in and near around Oasis are need. Therefore the area of woodland will be significantly incresed. It is obvious that reclaiming arable land, salinization and desertification caused the area of grassland significantly decreased.
