摘　　要：利用新疆昌吉佃坝绿洲区陆气相互作用观测站2020年3—11月的地表辐射观测数据和同期的天气现象观测记录数据,定量分析昌吉绿洲区不同时间尺度和不同天气条件下的地表辐射变化特征。结果表明:(1)辐射分量日均值和日峰值时间有季节性差异,特殊天气现象对辐射通量有影响。(2)地表辐射月曝辐量随季节变化显著。(3)地表反照率月平均日变化季节性明显,晴天时地表反照率呈平滑的“U形”曲线,非晴天时曲线变化皆不规则、不平滑。(4)不同天气下辐射分量有独特日变化特征,轻雾、雨天、大风、扬沙、多云天等典型天气会给辐射分量带来不同程度的衰减,雨天、大风和多云天气衰减最明显。The surface radiation observation data and weather phenomenon observation record data from March to November 2020 of the Dianba oasis area of Changji in Xinjiang,were used to quantitatively analyze the characteristics of surface radiation changes in Changji oasis area at different time scales and under different weather conditions.The results showed that:(1)There are seasonal differences between the daily mean value and the daily peak time of radiation components,and special weather phenomena has an impact on the radiation flux.(2)The monthly exposure to surface radiation varies significantly with seasons.(3)The monthly average daily variation of the surface albedo is obvious,and the surface albedo shows a smooth“U-shaped”curve on sunny days,and the curve changes irregularly and smoothly on non-sunny days.(4)The radiation component has unique daily variation characteristics under different weathers,and typical weather such as light fog,rainy days,strong winds,blowing sand,and cloudy days will bring different degrees of attenuation to the radiation component,and the attenuation of rainy days,strong winds and cloudy weather is the most obvious.
