摘　　要：新疆东部黑戈壁作为气候恶劣、人迹罕至的生态脆弱区,具有丰富的太阳能资源。利用红柳河陆气相互作用观测站2019年4、7、9月观测资料,分析东疆黑戈壁地表辐射及能量收支演变特征。结果表明:(1)地表辐射及能量收支各分量日变化均为单峰型。就不同季节而言,太阳总辐射和净辐射为夏季>春季>秋季,反射短波辐射为春季>夏季>秋季,地表和大气长波辐射为夏季>秋季>春季。(2)能量收支各分量季节变化明显,感热通量为春季>夏季>秋季,潜热通量为夏季>秋季>春季,地表土壤热通量为秋季>夏季>春季;能量分配在不同季节均以感热为主,地表土壤热通量次之,潜热通量极其微弱。(3)地表反照率日变化均为"U"型,季节变化表现为春季>秋季>夏季,月均值依次为0.29、0.27、0.26。Black gobi desert in eastern Xinjiang is an ecologically vulnerable area with harsh climate,inaccessible people,and being rich in solar energy resources. The characteristics of surface radiation and energy budget of black gobi desert in eastern Xinjiang were analyzed by using the observation data of Hongliu Land-Atmosphere Interaction Observation Station in April,July,and September 2019. The results demonstrated that:(1) The diurnal variation curves of surface radiation and energy flux components were all in unimodal type. The seasonal variation of surface radiation components was obvious:the extreme values of surface downward short-wave and net radiation ranked as summer >spring > autumn,and which of upward short-wave radiation ranked as spring > summer > autumn,while which of downward and upward long-wave radiation ranked as summer > autumn > spring.(2)The seasonal variation of surface energy flux was obvious:the extreme values of sensible heat flux ranked as spring > summer > autumn,latent heat flux ranked as summer > autumn > spring,while surface soil heat flux ranked as autumn > summer > spring. Sensible heat flux was the highest energy partitioning in different seasons,followed by the surface soil heat flux,while latent heat flux was very small.(3)The diurnal variation of surface albedo showed a U-shaped curve. The seasonal mean values of surface albedo ranked as spring > autumn > summer,were 0.29,0.27 and 0.26.
