中文摘要	利用2009年7-9月"巴丹吉林沙漠陆-气相互作用及其对区域气候的影响研究"试验所得观测资料,系统分析了夏季典型晴天下巴丹吉林沙漠和沙湖不同下垫面的辐射和能量收支特征。结果表明: (1)沙漠点和沙湖点土壤温湿度都有明显的日变化,表现为准正弦曲线。地表向下日较差逐步变小,日峰值和谷值都有明显的滞后性。5~10 cm土壤温,湿度受地表温度影响较大,20 cm以下不再有明显的日变化。沙湖点土壤湿度较大,且出现逆湿现象。(2)沙漠点和沙湖点太阳总辐射的日变化趋于一致;沙漠点大气长波辐射、地表长波辐射、有效辐射均比沙湖点略低,地表反射辐射大于沙湖点。沙漠的地表长波有效辐射均小于沙湖点,两观测点净辐射差异较小。(3)两观测点的地表反照率呈"U"形分布;沙漠点的日平均反照率为0.32,沙湖点为0.23。(4)沙漠点以感热输送为主,波文比为3.4;沙湖点则以潜热输送为主,波文比为0.2。
英文摘要	Diurnal variations of surface radiationand energy budget over different underlying surface in clear day were comparatively analyzed based on the observation data from land-atmosphere interactions experiments in Badain Jaran desert in summer of 2009. The results showed that: (1) Diurnal variations of soil temperature and humidity at two stations displayed quasi sinusoid, and the daily range of above-mentioned variables decreased with increased soil depth. Soil humidity in desert station is lesser, and increased from the surface down, as opposed to the sand-lake station, excepting the value is greater during the afternoon in 5 cm depth. (2) The trendency of global radiation at two stations is uniform. The surface long-wave radiation, atmospheric long-wave radiation, effective radiation is lesser, but outgoing radiation is greater in desert station relative to sand-lake station. the surface net radiation difference between two stations are small. (3) The albedo of two stations distributed by the shape of ’U’;the average daily albedo in desert station is 0.32, and sand-lake station is 0.23. (4) It was dominated by sensible heat transportation in surface energy budget and Bowen ratio is 3.4 in desert station. However, latent heat transportation occupied leading position at sand-lake station and Bowen ratio is only 0.2.
