摘　　要：以往的太阳辐射趋势研究大多基于站点数据,但稀少站点的观测并不能代表整个空间上的连续变化趋势。我国目前还没有利用时空连续的卫星辐射产品对太阳辐射变化趋势进行研究,由于NOAA卫星能够提供较长时间序列的太阳辐射数据,所以本研究选用其数据来研究中国西北地区1986—2015年的太阳总辐射时空变化趋势。研究结果表明:NOAA卫星辐射产品与地面观测数据变化趋势大体吻合,因此可以利用NOAA卫星辐射产品来研究太阳辐射的时空变化趋势。1986—2015年西北地区总太阳辐射总体呈整体缓慢上升趋势;季节性平均变化趋势表现为:春季、夏季和冬季呈缓慢上升趋势,秋季变化呈下降趋势;空间上的变化为:在新疆喀什、伊宁、塔城、阿勒泰地区,青海的果洛、玉树,宁夏银川,陕西延安以及甘肃兰州为上升趋势,新疆的乌鲁木齐、若羌,陕西西安,青海的格尔木地区以及甘肃敦煌地区为下降趋势。Since the previous solar radiation trend studies are based on site data, the observations of rare sites do not represent continuous trends in the entire space. In China, there is no research on the use of temporal and spatial l continuous satellite radiation products to study the trend of solar radiation. Since NOAA/AVHRR satellites can provide longer time series solar radiation data, this paper uses NOAA/AVHRR satellite radiation products to study the temporal and spatial trends of solar radiation in the region northwest China during 1986—2015. The results of this paper show that the trend of NOAA/AVHRR satellite radiation products are in good agreement with the trend of ground observation data, so NOAA/AVHRR satellite radiation products can be used to study the temporal and spatial trends of solar radiation. during 1986—2015. The total solar radiation in the northwest China showed an overall slow upward trend. The seasonal average trend of total solar radiation in the northwestern region showed a slow upward trend in spring, summer and winter, and a downward trend in autumn. during 1986—2015.The spatial variation trend of total solar radiation in northwest China during 1986—2015 is: in Kashgar,Yining, Tacheng and Altay areas of Xinjiang, Guoluo, Yushu in Qinghai, Yinchuan in Ningxia, Yan’an in Shaanxi and Lanzhou in Gansu are rising trends, Xinjiang Urumqi, Ruoqiang, Xi’an, Shaanxi, Golmud in Qinghai and Dunhuang in Gansu are in a downward trend.
