中文摘要	利用两期TM数据对塔里木河上游典型绿洲的地表温度进行反演,并查询实时陆面地表温度进行了对比检验,其差值均在1.5℃以内。在此基础上,分析了不同时期塔里木河上游典型绿洲的温度时空变化,结果表明:(1)2007~2011年,下垫面温度主要集中在18~51℃,其中,水体温度在18~24℃(低温区),耕地地表温度在24~29℃(中温区),林地地表温度在29~36℃(偏高温区),绿洲周边的裸地地表温度在36~42℃(高温区),远离绿洲的荒漠地带地表温度在42~51℃(极高温区);(2)2007~2011年,水体地表温度平均增高0~4℃,植被地表温度平均增高0~12℃,绿洲周边的裸地地表温度平均增高0~7℃,远离绿洲的荒漠地带地表温度平均增高0~9℃。其中林地对温度的变化影响较大。总之,地表温度呈现沿中心逐渐向四周增高的分布规律,表现出明显的"冷岛效应"。此研究对进一步理解塔里木河上游绿洲土壤-植被-大气系统能量交换状况以及我国西北干旱、半干旱区域地表热量分布差异特征具有重要的意义。
英文摘要	Land surface temperature (LST) is the key factor of the thermal state of the earth system and the balance of water and heat. The author used the mono - window algorithm by Qin Zhi - hao and TM data to retrieve land surface temperature of the typical oasis in the upper reaches of Tarim river between 2007 and 2011,and the actual land surface temperature was used to test it. The results shows: (1) The underlying surface was mainly concentrated in the 18 ~ 51℃,the water surface temperature was about 18 ~ 24℃, the farmland surface temperature was about 24 ~ 29℃,the forestland surface temperature was about 29 ~ 36℃,the bare land around the oasis surface temperature was the 36 ~ 42℃,away from the oasis in the desert regions of the surface temperature was 42 ~ 51℃. The surface temperature of water body was the lowest,but the bare land and desert was the highest. (2) During the 2007 ~ 2011,land surface temperature changes in the study area showed that the water surface temperature increased about 0 ~ 4℃ on average,the vegetation surface temperature increased about 0 ~ 12℃ on average,the bare - land surface temperature increased about 0 ~ 7℃ on average,the desert away from the oasis surface temperature increased about 0 ~ 9℃ on average. Through the above research,we could get a conclusion that the surface temperature trend was increasing year by year. The land surface temperature was ascending from oasis center to desert gradually,that it performed " cool island" clearly. This is very important significance for further understanding 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.
