摘　　要：为了解锡林浩特地区太阳紫外辐射变化规律,并为全球太阳紫外辐射研究提供可靠的基础依据和参考。根据锡林浩特国家气候观象台2007—2009年太阳总辐射与紫外辐射观测资料,笔者运用数理统计学方法,对锡林浩特地区太阳紫外辐射UV-B极值进行分析。结果表明：太阳紫外辐射是太阳总辐射的一部分,日极值出现在12：30左右并且有云的天气。一天内早晚小,中午大,总体变化范围为0.01~3.05W/m2。年极值只有冬季出现在晴天,春、夏、秋季均出现在有云的天气,最大值出现在7月为3.05W/m2。锡林浩特地区紫外辐射日瞬时极值变化和季节变化的主要趋势与太阳总辐射一致,瞬时极值可出现在不同云量的天气条件下,一年四季紫外辐射强度均在安全范围变化。To understand the changes of solar ultraviolet radiation in Xilinhaote area and to study the global solar ultraviolet radiation to provide a reliable basis and reference for the foundation. According to the 2007-2009 global solar radiation and UV radiation observation data from Xilinhaote national climate observatory, the author used mathematical statistical methods and analyzed UV-B solar extreme ultraviolet radiation of Xilinhaote region. The results showed that： solar UV radiation was a part of global solar radiation, and the daily extreme came in around 12：30 or cloudy day. Small radiation occurred in the morning and evening, big in the lunch, and the overall change in the range of 0.01-3.05 W/m 2 . Annul extreme came only in sunny winter, spring, summer, and cloudy autumn, maximum in July for the 3.05 W/m 2 . Extreme ultraviolet radiation in Xilinhaote region at instantaneous change of the main trends and seasonal variation were consistent with the global solar radiation, extreme transient could appear in a cloudy day under weather conditions, UV radiation intensity throughout the year changed in the safe range.
