摘　　要：利用位于河北定兴县的中国气象局固城生态与农业试验站2005年7月～2007年2月期间观测的太阳辐射各分量的资料,详细分析了该站太阳辐射及地表反射的基本特征。分别对到达地表的太阳总辐射、地面反射短波辐射、地表反射率、净辐射、光合有效辐射和紫外辐射(UV-B)的日、年变化特征进行了分析,揭示了该地区的辐射平衡特征。同时分析并给出了光合有效辐射和紫外UV-B辐射占太阳总辐射比值的变化规律。The characteristics of the solar radiation and radiation budget were analyzed by using the surface radiation data observed at Gucbeng Meteorological Station of Hebei province for the period from July 2005 to February 2007. The daily and annual change of global radiation, surface albedo, net radiation, photosynthetic active radiation and ultraviolet radiation on the wavelength between 290nm to 320nm are analyzed. Meanwhile, the ratios of the net radiation, photosynthetic active radiation and ultraviolet radiation to global radiation are calculated and their daily and annual variations are given.
