摘　　要：利用广州地区１９８５－１９９０年的太阳分光辐射的连续观测资料（观测角度为２３°１１’），研究了广州地区紫外辐射、可见光辐射（光合有效辐射）、近红外辐射的某些特征，结果指出，每年７－１０月份各分光辐射及总辐射总量较大。月总辐射中可见光辐射占总辐射的百分比年平均为４７．３％，相应的紫外辐射和近红外辐射分别占７．１％和４５．６％。文中还分析了晴天条件下分光辐射的变化和１９９０年紫外辐射变化的某些特征，并分析和讨论了分光辐射与云量、日照时间等因子的相关。Characteristics of thesolar ultraviolet radiation,visible radistion(photosynthet-ically active radiation) and near infrared radiation are examined by using the data of so-lar spectral radiations(observed angle is 23°11’)observed in the period of 1985-1990 inthe Guangzhou district.The result shows that the monthly amounts of the solar spectralradiations and the total radiation are larger in July-October every year. The monthlymean ratio of visible to total radiation is 47.3%,infrared to total is 45.6%and UV tototal is 7.1%, Furthermore,some features of the variations of solar spectral radiationsin clear sky and UV radiation in 1990 are also given in the paper.And,the correlationsof spectral radiations to cloud amounts,insolation duration and other factors are ana-lyzed and discussed.
