摘要
The characteristics of land use/cover change of the Cele oasis, in the southern margin of Tarim Basin, from 1990 to 2018 were explored and attributed based on four phases of land use and remote sensing images, as well as meteorological, hydrological, and socio-economic data. We found that the land use types in the Cele oasis changed substantially: The farmland area expanded to the surrounding area, the forest land distribution area shifted substantially, and the coverage of grassland changed frequently. Overall, 138.41 km2 (53.85%) of the total area was transformed. In descending order, the single dynamic attitude was high covered grassland>farmland> low cover grassland>construction land>medium covered>grassland unused land>forest land, and in descending order, the double directional trend was high covered grassland>farmland>low cover grassland>construction land> forest land>medium covered>grassland unused land. The results also showed that the vegetation index of the green continent was less than 0, which indicates that forest land and grassland have been in a state of degradation. The driving forces of land use change in the oasis were population, precipitation, and runoff, based on the factors influencing surface cover in the oasis.
