• Cover change
• Land surface temperature (LST)
• Spatial distribution

In this study landsat TM/ETM+ was used to analyze the spatial distribution change of LST and ET in terms of LUCC difference from 1987 to 2000. The LST was retrieved by Qin et al.'s algorithm and the daily ET was estimated using the SEBAL model. The results show that the LST and ET of 2000 both were completely different from those of 1987 due to the LUCC variation in the 13 years. The land use/cover characteristics mainly controlled the spatial distribution of the LST and ET. The analysis indicated that LST possessed evidently negative correlation with the ET for all land cover types. The analysis of LST and ET in response to LUCC would help the decision maker for better future planning to protect ecological environment.
