| 摘 要： | 利用甘肃省内26个气象站的1963~2012年的逐月平均气温和降水资料,运用线性回归、距平分析、和气候突变分析等方法,对甘肃省近50a来气温和降水量的变化趋势和突变特征进行分析,并利用arcGIS10.0软件,对气温和降水的距平值进行空间插值。结果表明:近50a来甘肃省年平均气温呈现增暖趋势,以0.3℃/10a的速率显著上升;近50a来甘肃省年均降水整体呈现减少趋势,以5.1mm/10a趋势明显减少,1997年的降水量只有191.3mm,降水的变化幅度较大;近50a来甘肃省年均气温和降水均无明显的突变时间区域。

| Abstract: | Based on the monthly temperature and precipitation data in Gansu from 1963 to 2012,the climate change trend was analyzed by using linear fitting method,departure analysis and climate abrupt change,and using arcGIS10.0 software,the temperature and precipitation anomaly spatial interpolation.The result showed that the average of temperature of Gansu increased with the rate of 0.3℃ /10a over recent 50 years.The average of precipitation descended obviously with the rate of 5.1mm /10a over recent 50 years.Especially in 1997,precipitation was only 191.3mm.Both of the average of temperature and precipitation had no abrupt change over recent 50 years. |
