- Abstract:
-
The mono-window algorithm and TM data were used to retrieve land surface temperature in the typical oasis of the Weigan River-Kuqa River between 1989 and 2011, and the actual land surface temperature was used to verify the calibrated results. The temperature is divided into low temperature zone of 9.9~13.9℃, secondary low temperature zone of 13.9~19.9℃, medium temperature zone of 19.9~25.9℃, secondary high temperature zone of 25.9~31.9℃, high temperature zone of 31.9~37.9℃, and extremely high temperature zone of 37.9~41.9℃. The results show that: (1) on the time scales, the surface temperature of water body was the lowest and the bare land and desert had the highest temperature, the temperature is lower in 1989 than 2011, there is no low temperature zone in 2011 and there are no high temperature zone and extremely high temperature zone in 1989, the lowest temperature is 10.65℃ in 1989, and it was 15.78 ℃ in 2011, the highest temperature is 29.30℃ in 1989, and it was 41.82℃ in 2011; (2) on the spatial scales, land surface temperature changes in the study area showed that the temperature had a huge changes; (3) the gobi and desert were warming far more quickly than the oasis, as a result, the temperature of the oasis was lower than the surrounding which results in a ‘cold spot’ phenomenon. This is very significant in terms of further understanding of the energy exchange status of soil-plant-atmosphere system and the differences of regional heat distribution in arid and semi-arid area of the northwest China.
