摘　　要：利用白银市区2003年3月～11月所采集的到达地面的太阳紫外辐射数据,分析了白银市区紫外辐射的月、日变化规律以及气象因子对紫外辐射的影响程度。分析结果表明,一年中,夏季的紫外线辐射最大,春季次之,秋季偏弱,冬季最弱;一日中,早晚时段辐射量小,中午时段辐射量大;云、气温、湿度等气象要素与紫外线辐射强度密切相关,尤其是云对紫外线有很大衰减作用。The paper analyzed the characteristics of the monthly and the daily variation of solar ultraviolet radiation and the effect of meteorological factors to solar ultraviolet radiation using the surface solar ultraviolet radiation data from March to November in 2003 at Baiyin.Results show that in one year the solar ultraviolet radiation is highest in summer,higher in spring,lower in autumn,lowest in winter. in one day the solar ultraviolet radiation is high in noontime,low in the morning and in the afternoon.The meteorologic factors such as cloud,temperature,humidity etc are very correlative with the solar ultraviolet radiation.
