摘　　要：To further reveal the variation laws of ultraviolet radiation to provide better service for production and people＇s life, based on observation data of solar ultraviolet radiation obtained by Xilinhot National Climate Observatory in 2007-2012, the variation laws of solar ultraviolet radiation and its relationship with meteorological factors in different cloud conditions in Xilinhote were analyzed by using the mathematical and statistical methods and SPSS 11.5 software. The results showed that the solar ultraviolet radiation had obvious daily, seasonal and annual variations; the solar ultraviolet radiation was weak in the morning and evening but strong at noon; the maximum appeared from June to August, while the minimum appeared in November and December. It had significant correlation with total solar radiation, photosynthetically active radiation, air temperature, air humidity and ground temperature （0-5 cm）. At present, the maximum intensity of ultraviolet radiation （UV-B） was 0.20-1.91 W/m2 from January to March and 0.13-1.43 W/m2 from October to De- cember respectively, which were lower than the safety standard for people and animals （2 W/mZ）. However, the maximum might appear from April to September, ranging from 2.02 to 3.39 W/m2, which was easy to bring a threat and harm to people and animals.为进一步揭示紫外辐射的变化规律,更好地为生产和人们的生活服务,基于锡林浩特国家气候观象台2007~2012年太阳紫外辐射观测资料,运用数理统计学方法与SPSS 11.5软件,分析了锡林浩特地区不同云况条件下太阳紫外辐射规律及与气象要素的相互关系。结果表明:太阳紫外辐射存在明显的日、季、年变化规律。一日内早晚小,中午大。一年内最高值出现在6~8月,最低值出现在11~12月。且与太阳总辐射、光合有效辐射、空气温度、空气湿度、地温0~5 cm存在较显著的相关性。目前锡林浩特地区紫外辐射强度(UV-B)1~3、10~12月最大值范围分别为0.20~1.91、0.13~1.43 W/m2,低于人和动物的安全标准2 W/m2,4~9月可出现最大值范围为2.02~3.39 W/m2,容易对人和动物造成威胁和伤害。
