中文摘要	以巴丹吉林沙漠苏木巴润吉林观测站地温与气象数据为基础,分析巴丹吉林沙漠腹地地温变化特征。结果表明: (1)巴丹吉林沙漠地温、气温日变化特征明显,最高值出现时刻为17: 00左右,相对东部地区滞后3 h; 不同季节地温与气温变化趋势基本保持一致,地温变化相对气温、太阳辐射明显滞后; (2)地温在11月末至2月降至0 ℃以下,深度60 cm下全年高于0 ℃,地温变化幅度随深度增加逐渐减小; (3)地温变化幅度直接由太阳辐射强度决定,但影响地温的环境因子存在季节性特征,春、秋、冬季主要影响因子为气温、太阳辐射及降水,气温和太阳辐射的影响具有连续性,降水则导致地温骤减,风速仅在夏季影响地温。
英文摘要	Based on the soil temperature and meteorological data from observation station, characteristics of soil temperature variation are analyzed in the Badain Jaran Desert Hinterland. The results are as follows: (1) The diurnal variations of soil and air temperature are significant, and the highest temperature appears at 17: 00, which is about 2 hours later comparing with eastern region. The variation of soil temperature is nearly equal to air temperature, but clearly lags behind air temperature and solar radiation in different seasons; (2) The soil temperature dips to 0 ℃ from late November to February. When soil depth is below 60 cm, soil temperature keeps above 0 ℃ the whole year, and the variation range of soil temperature decreases with the increase of soildepth; (3) The variation of soil temperature is determined by solar radiation directly. The environmental factors which affects the soil temperature are seasonal. In winter, spring and autumn the major factors are air temperature, solar radiation and precipitation, while the velocity of wind is another significant factor in summer. Air temperature and solar radiation have continuity effect on soil temperature among these factors, while precipitation causes the sudden declines of soil temperature directly.
