利用青岛市1961—2012逐日日照时数资料,采用 Angstrorm 公式计算了逐日太阳总辐射,并利用线性倾向估计法和Pettitt突变检验方法对青岛市年和四季太阳总辐射的变化进行了分析。结果表明,1961—2012年间青岛市年太阳总辐射呈明显减小趋势,其气候倾向率为-86.69 MJ/10a,达到了极显著水平。年太阳总辐射时间序列的减小突变发生在1993年。青岛市四季太阳总辐射均呈明显的减小趋势,其中夏季太阳总辐射的减小速率最大,春季减小速率最小,四季太阳总辐射的气候倾向率分别为-8.41,-40.23,-17.79和-20.26 MJ/10a。夏季、秋季和冬季太阳总辐射时间序列出现减小突变,突变出现年份分别为1993,1998和1996。青岛市年太阳总辐射与年平均风速呈显著正相关,而与年平均实际水汽压和相对湿度呈显著负相关。
利用青島市1961—2012逐日日照時數資料,採用 Angstrorm 公式計算瞭逐日太暘總輻射,併利用線性傾嚮估計法和Pettitt突變檢驗方法對青島市年和四季太暘總輻射的變化進行瞭分析。結果錶明,1961—2012年間青島市年太暘總輻射呈明顯減小趨勢,其氣候傾嚮率為-86.69 MJ/10a,達到瞭極顯著水平。年太暘總輻射時間序列的減小突變髮生在1993年。青島市四季太暘總輻射均呈明顯的減小趨勢,其中夏季太暘總輻射的減小速率最大,春季減小速率最小,四季太暘總輻射的氣候傾嚮率分彆為-8.41,-40.23,-17.79和-20.26 MJ/10a。夏季、鞦季和鼕季太暘總輻射時間序列齣現減小突變,突變齣現年份分彆為1993,1998和1996。青島市年太暘總輻射與年平均風速呈顯著正相關,而與年平均實際水汽壓和相對濕度呈顯著負相關。

In this study,the Angstrom formula was used to calculate global solar radiation based on daily sunshine duration data of Qingdao station during the period 1961-2012.The temporal trend and abrupt change of annual and seasonal total global solar radiation were detected with the methods of linear regres-sion and Pettitt test,respectively.The results showed that the annual global solar radiation in Qingdao ex-hibited decreasing trend during 1961—2010 and the decreasing rate was 86.69 MJ/decade.A significant downward shift in annual global solar radiation was detected in 1 9 9 3 through the Pettitt test.On the sea-sonal scale,the significant decreasing trends were identified in summer,autumn,and winter.The decrea-sing rate in spring,summer,autumn,and winter were 8.41,40.23,17.79,and 20.26 MJ/decade,re-spectively.Significant downward shifts in summer,autumn,and winter were detected in 1993,1998,and 1996,respectively.Annual global solar radiation in Qingdao had significantly positive correlation with an-nual mean wind speed,and significant negative correlations with annual mean actual vapor pressure,and relative humidity.
