中文摘要：

使用遥感与地理信息系统技术,利用2012年12月-2013年2月的MODIS地表温度数据产品对巴丹吉林沙漠地区冬季地表温度进行研究.将巴丹吉林沙漠分为湖泊区、沙漠外围区和沙漠周边区3个区域,旨在对3个区域的白天和夜晚地表温度进行研究对比.结果显示位于巴丹吉林沙漠腹地的湖泊区冬季白天和夜晚平均地表温度为6.10℃和-14.37℃,沙漠外围区分别为4.25℃和-15.44℃,沙漠周边区分别为4.07℃和-14.29℃,存在沙漠腹地湖泊区地表温度明显高于沙漠其他区域的＂暖岛效应＂,其形成机制可能与远程地下水补给湖泊群有关.

英文摘要：

In this paper, remote sensing and geographic information system technology were used to study the winter land surface temperature in Badain Jaran Desert with December 2012 to February 2013 MODIS LST data products. Badain Jaran Desert was divided into three regions： lake region, peripheral region and desert surrounding region. Day and night LST of the three regions were contrasted. The results show that lake region located in the hinterland of the Badain Jaran Desert was warmer than the other regions. Winter day and night average surface temperatures in lake district were 6.10 ℃ and -14.37 ℃, those in the peripheral region were 4.25 ℃ and -15.44 ℃ and the desert surrounding region were 4.07 ℃ and -14.29 ℃. The results also show that desert lake area in winter underwent surface temperature significantly higher than other regions of the desert, i.e. the ＂warm island effect＂, and its formation mechanism might have been related to remote groundwater recharged lakes.
