| Abstract: | Based on Landsat 7 ETM plus remote sensing data,the real land surface temperature of the typical oasis was retrieved under the clear weather of summer in arid region using a thermal infrared band of satellite image.The thermal field distributions were analyzed by using a satellite image overlaying analysis,a histogram comparison,a buffer analysis,a spatial autocorrelation analysis and profile-line analysis methods,etc..The results indicate that the thermal field distributions of oasis are of significantly p... |
