摘要：

利用1961—2010年河北省周边7个太阳辐射观测站的资料，拟合得出相对精确的河北省太阳直接辐射经验公式，分析了河北省太阳直接辐射时空变化特征。结果表明：河北省近50 a来太阳直接辐射年总量总体呈明显的下降趋势。其中，下降幅度相对较大的石家庄为25%，下降幅度相对较小的唐山为11%。河北省水平面太阳直接辐射年总量近50 a平均值空间差异较大，<2540 MJ·m^-2 主要分布在邢台南部，>3510 MJ·m^-2 主要分布在张家口西北部，大部分地区介于2540—3300 MJ·m^-2 。河北省太阳能资源开发利用潜力比较大的区域主要在张家口的坝上地区。

Abstract:

Based on the observed solar radiation data at 7 stations from 1961 to 2010 in Hebei province, a relatively accurate empirical formula on direct solar radiation was obtained. The temporal and spatial distribution of solar radiation was analyzed in Heibei province. The results indicate that the total annual solar radiation is in a decreasing trend, and the relatively higher and lower decreasing amplitudes are 25% in Shijiazhuang and 11% in Tangshan. The spatial variation of the horizontal direct solar radiation in Hebei province in recent 50 years is quite different. The area with the value less than 2540 MJ·m^-2 is mainly in the southern Xingtai, while the that with the value more than 3510 MJ·m^-2 is in the northwestern Zhangjiakou. The values of solar radiation are between 2540-3300 MJ·m^-2 in most areas of Hebei province. The potential ability for the development and utilization of solar energy resources is great in the dam area of Zhangjiakou in Hebei province.
