- Abstract:
-
Based on remote sensing and GIS, the land use change and the thermal environment were analyzed by using two sets of ETM+ images of 2001 and 2011 in this study. The result showed that the expansion of cultivated land and decrease of other land were the most obvious characteristics of land use change during 2001—2011. The cultivated land increased from 4.84×105 hm2 in 2001 to 5.82×105 hm2 in 2011 and the other land decreased from 5.00×106 hm2 in 2001 to 3.89×105 hm2 in 2011. The surface temperature of different land use types had significant difference. The descending order of the mean land surface temperature of land use type was: sand, other land, saline-alkali soil, cultivated land, woodland, grassland, waters. This study indicated the land use change especially the cultivated land expansion and other land decrease influenced the regional thermal environment dramatically. The oasis thermal environment shows a downward trend.
