中文摘要	利用2013年7月、10月和2014年1月、4月巴丹吉林沙漠北缘拐子湖流动沙地地表辐射、土壤热通量、土壤温湿度和湍流通量等观测资料,分析了拐子湖地区地表辐射收支和能量通量在不同季节条件下的日变化特征及能量分配和闭合状况。结果表明:地表辐射各分量和能量平衡分量的月平均日变化结果整体均表现为标准的单峰型日循环形态,受不同季节影响,日变化曲线存在显著的季节变化差异,各分量均呈7月最大、1月最小、4月大于10月,1月和7月的R_(s)、R_(s)、R_(l)、R_(l)、R_n日均值依次为98.9W·m~(-2)和614.6W·m~(-2)、34.6W·m~(-2)和87.3W ·m~(-2)、276.9W·m~(-2)和494.2W·m~(-2)、214.8W·m~(-2)和385.0W·m~(-2)、0.4W·m~(-2)和128.7W·m~(-2)。与塔中、肖塘等地相比,该区域具有相对较高的地表反照率,整体呈冬季高夏季低,年均0.34。1月和7月的H、LE、G_0日均值依次为4.7W·m~(-2)和78.8W·m~(-2)、0.3W·m~(-2)和20.3W·m~(-2)、2.9W·m~(-2)和35.0W·m~(-2)。从能量分配来看,研究区干旱的气候和极低的植被覆盖造成了各季节全天潜热通量占净辐射份额始终较小,白天以感热为能量的主要消耗形式,土壤热通量次之。此外,R_n于正午达到日峰值后逐渐减小,受辐射强迫升温的地面以感热形式对空气的热量输送却不断持续,而促使H/R_n日间始终保持明显的增长趋势。
英文摘要	In this paper,we analyzed the monthly mean diurnal variation characteristics of the surface radiation budget,energy flux and energy closure condition over the Guaizi Lake shifting sandy land in different seasons by use of surface radiation and turbulent flux data from July 2013 to April 2014.The result indicated that under no precipitation condition,the monthly average daily variation of each component of surface radiation and energy balance both showed the standard unimodal-type daily cycle pattern.Meanwhile,influenced by the difference of seasons,the daily variation curve had apparent seasonal variation,with every component manifested a feature of being maximum in July and minimum in January,and of being bigger in April than in October.The diurnal average of R_(s),R_(s),R_(l),R_(l),Rnin January and July was 98.9 W·m~(-2) and 614.6 W·m~(-2), 34.6 W·m~(-2) and 87.3 W·m~(-2),276.9 W·m~(-2) and 494.2 W·m~(-2),214.8 W·m~(-2) and 385.0 W·m~(-2), 0.35 W·m~(-2) and 128.7 W·m~(-2),respectively.The annual average surface albedo was 0.34,which was higher than in Tazhong and Xiaotang.The surface albedo in January was higher in Guaizi Lake area than in July. The diurnal average of H,LE,G_0 in January and July was 4.7 W·m~(-2) and 78.8 W·m~(-2),0.3 W· m~(-2) and 20.3 W·m~(-2),2.9 W·m~(-2) and 35.0 W·m~(-2),respectively.From the perspective of energy distribution, the whole day latent heat flux in all seasons of the Guaizi Lake shifting sandy land always occupied a relatively low percent of net radiation,and in daytime,sensible heat was its main energy consumption form, second to which was soil heat conduction.After noon,R_n gradually declined,while influxes of sensible heat from ground surface to near surface air increased because of the lasting radiation force.Therefore,H/R_n kept increasing during day time.
