Abstract：This study selected Yutian Oasis as the study area,using remote sensing technology,the surface temperature which can express the oasis land surface energy was used to analyze space distribution characteristic of Xinjiang oasis thermal environment.Specific research of this study includes using Landsat 8 data as the data source of this research,utilizing thermal infrared remote sensing technology,collecting and combining the meteorological data of the study area calculation parameters such as brightness temperature,atmospheric transmittance and the surface emissivity,finally use the split window algorithm to retrieving land surface temperature.Calculating the vegetation coverage,and analysis of the relationship between vegetation coverage and the surface temperature,and the result shows that vegetation coverage and surface temperature has strong negative correlation,R2=0.979 2.Through spatial overlay analysis the land surface temperature and land use type,it shows that the land surface temperature of the study area appears to increase along the Oasis Center to around gradually,with the mean surface temperature from low to high order as water (18.02 ℃),farmland (24.23 ℃),forest and grassland (26.3 ℃),saline (35.34 ℃),others (37.87 ℃℃),the desert (39.64 ℃).
