通过对阿克达拉站2005年7月—2010年11月紫外线B波段实测资料的分析得出：阿克达拉UV-B的日曝辐量年平均在26 159 J/m2左右。夏季值最高,为42 090 J/m2,次高是春季,为33 147 J/m2,第三是秋季,为17 476 J/m2,最低是冬季,为11 921 J/m2,呈现出较明显的季节性特征。无论是晴好天气还是其它正常天气条件下,这几年的UV-B强度总体上呈现出上升趋势。紫外线辐射强度日变化特征：中午强,早晚弱,关于一天中最大值出现的时间呈对称分布。日变化特征曲线的斜率,夏季最大,其次是春季和秋季,冬季最小,一天中紫外线辐射的起止时间随着季节的变化而变化。
通過對阿剋達拉站2005年7月—2010年11月紫外線B波段實測資料的分析得齣：阿剋達拉UV-B的日曝輻量年平均在26 159 J/m2左右。夏季值最高,為42 090 J/m2,次高是春季,為33 147 J/m2,第三是鞦季,為17 476 J/m2,最低是鼕季,為11 921 J/m2,呈現齣較明顯的季節性特徵。無論是晴好天氣還是其它正常天氣條件下,這幾年的UV-B彊度總體上呈現齣上升趨勢。紫外線輻射彊度日變化特徵：中午彊,早晚弱,關于一天中最大值齣現的時間呈對稱分佈。日變化特徵麯線的斜率,夏季最大,其次是春季和鞦季,鼕季最小,一天中紫外線輻射的起止時間隨著季節的變化而變化。

According to the analysis on the UV-B observational data from July,2005 to November,2010 at Akedala weather station,the average of the UV-B radiant exposure at Akedala was 25 467 J/m2.The highest was 42 674 J/ m2 in summer and the second highest was 33 147J/m2 in spring,and it was 17 476 J/ m2 and 11 886 J/m2 in autumn and winter respectively.The change of UV-B took on obviously seasonal characteristics.Under sunny or other normal weather condition,it always presented an increase trend.The characteristics of the UV-B were as follows： It was strong at noon and weak in the morning and evening distributing symmetrically about occurring time of the maximum.The slope in the daily variation statistical graph was highest in summer,then in autumn and spring,and the least in winter.The UV-B daily starting and ending time changed along with seasons.
