This study take landsat TM/ETM in 1999 and 2009 as an original data and three different scales oasis for isolated oasis in Yutian Cele area in southern of Tarim basin as study area. By the normalized linear unmixed model, we calculate vegetation abundance and percent of impervious surface based on vegetation-impervious surface-soil model, analyze the correlation between surface temperature with the vegetation and impervious, examined the relationship between the scales of the oasis and correlation the surface parameter sand land surface temperatures. The results show that the abundance of vegetation and surface temperature has more significant negative correlation with the weak positive correlation between amount of impervious surface and the land surface temperature in some oasis areas. With the increment of the oasis scales, the correlations coefficient between vegetation abundance and LST and the correlations coefficient between impervious surface and surface temperature raise with an obvious trend, the results indicates that with increase of oasis scales, the extend of local climate change, particularly as oasis ‘cool island effect’, was increased as the time from 1999 to 2009. Meanwhile, as growing of rural urbanization, the increasing of proportion of impervious surface present the more significant effect to land surface temperature of oasis.
