A Study of Retrieval Land Surface Temperature and Evapotranspiration in Response to LUCC Based on Remote Sensing Data

摘要

In this study landsat TM/ETM+ was used to analyze the spatial distribution change of LST and ET in terms of LUCC different from 1987 to 2000. The LST was retrieved by Qin et al.'s algorithm and the daily ET was estimated using SEBAL model. The results show that the LST and ET of 2000 both were completely different from those of 1987 due to the LUCC vary between 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.
