摘要
选取新疆维吾尔自治区吐鲁番站近30年(1985-2014年)总辐射量、日照时间资料,将其与乌鲁木齐、焉耆两站同期资料进行对比分析,并使用SPSS和R软件对年度资料进行了均一性检验。结果表明,因探测环境遭受严重破坏,吐鲁番观测站辐射量、日照时间资料与两参照观测站辐射量、日照时间资料相比一致性较差,其中1992、2010年总辐射量资料发生了不连续变化,2010年日照时间资料发生了不连续变化(未通过0.01显著水平检验);月值自2010年起每年1-3月、9-12月总辐射量、日照时间资料均发生了不连续变化(未通过0.01显著水平检验)。探究其原因,是因吐鲁番站观测场正南方和西南方密集重叠的高层建筑,秋冬季随着太阳高度角的变化遮蔽了整个观测场所致。
The data of total radiation and sunshine duration of Turpan meteorological observatory in Xinjiang Uygur autonomous region in last 30 years（1985-2014） were selected for a comparative analysis with the data of Urumqi and Yanqi meteorological observatory of the same period,and the SPSS and the R analysis software were used for the homogeneity test of annual data. The results showed that,the data of radiation and sunshine duration of Turpan meteorological observatory and that of the comparative meteorological observatories had poor coherence as the detection environment having been severely damaged. Of which,the total radiation data occurred uncontinuous changes in 1992 and 2010 and the sunshine duration data occurred uncontinuous change in 2010（failing to pass the significance level test at α=0.01）. Since 2010,the data of total radiation and sunshine duration of every month from January to March and September to December has occurred uncontinuous changes（failing to pass the significance level test at α=0.01）. The explanation is that the clusters of high-rise buildings in south and southwest of Turpan observation site overshadow the whole observation site with the changes of sun elevation angles in autumn and winter.
