太阳辐射是控制气候形成的基本能量，分析太阳辐射的变化有助于深入理解气候变化的原因。本文利用海河流域及其周边46 个气象站气象资料以及TOMS (the Total Ozone Mapping Spectrometer) 卫星反演逐日气溶胶指数资料，分析了海河流域太阳辐射的时空变化规律，并对太阳辐射变化的原因进行了初步分析。研究结果表明，1957-2008 年海河流域太阳总辐射呈明显下降趋势，其中太阳直接辐射下降趋势明显，散射辐射呈增加趋势；从空间分布上看，流域南部和冀东沿海的人口高密度区相比流域北部的燕山和太行山人口低密度区太阳总辐射减小趋势更为明显。对太阳辐射下降原因的研究表明，人类活动造成气溶胶的显著增加可能是引起太阳辐射下降的重要原因。

Solar radiation is a key factor in most climate processes. In surface hydrology, it controls the energy balance of the catchment, thus deeply influences the water balance. In this paper, the temporal and spatial variations of solar radiation and the cause of the variation have been analyzed based on meteorological data obtained from 46 national meteorological stations and aerosol index data from TOMS in the Haihe River Basin and surrounding areas. The results show that solar radiation and direct radiation significantly decreased, while the scatter radiation increased during the period 1957-2008. In terms of solar radiation, the densely populated areas have a greater decreasing trend than the scarcely populated ones. The spatial distribution of the increase in aerosol index is consistent with that of the decrease in aerosol index. The increase in aerosol resulting from human activities is the important reason for the decrease in solar radiation.
