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

The condition of land use/cover change (LUCC) is an important influence factor of the land surface temperature (LST) and the evapotranspiration (ET). Herein LST and ET were retrieved by Qin et alpsilas mono-window algorithm and SEBAL model, respectively, based on landsat TM/ETM+ data. The analysis of retrieval result indicated that the change of the land use/cover was remarkable during 9 years from 1990 to 1999 in the Sangong River in Fukang of Xinjiang province. The land use/cover characteristics mainly controlled the spatial distribution of the LST and ET. The distributions of LST and ET were all a single-apex model over different land use/cover. The frequency distribution characteristic of LST in 1999 was roughly consistent with those in 1990, but the change ranges of LST over different land use/cover in 1999 were large than those in 1990. ET has presented the same change characteristic, and the day ETs of 1999 over different land use/cover were larger than those of 1990.The results demonstrate that LST possessed evidently negative correlation with the ET for all land cover types.
