| 摘 要： | 对甘肃省５３个测站１９６１—１９９５年年平均总云量资料用ＥＯＦ等方法进行分析研究。结果表明：甘肃省年平均总云量变化在空间上具有很好的一致性，但也存在明显的差异；３５年来甘肃省年平均总云量变化趋势是在波动中逐渐减少，全省平均减少０．１９成，尤以９０年代云量减少最显著；甘肃省总云量年际变化具有７年周期。

| Abstract: | By analysing 53 stations data of Gansu from 1961 to 1995 with EOF etc. methods, the paper gets some conclusion: the annual average whole cloud amount change has a fine spatial consistency but obvious difference, and it has been decreasing with wave motion in recent 35 years, mean decreasing 19%, especially in 1990s, its annual change has a 7 year period. |
