摘要:
根据酒泉地面气象站1955~2004年历年逐月平均气温和逐月降水量资料,运用累积距平方法和Mann-Kendall方法进行酒泉盆地50a来气温和降水趋势和突变的分析。结果表明:酒泉盆地气温整体上呈一定的上升趋势,1955~1985年为缓慢的下降,1985年后出现了明显的上升趋势,而降水没有任何明显的趋势变化,波动较大且频繁。
Hydrological data series from 1955-2004 inthe Jiuquan basin were used to analyze the trend and mutation of temperature and precipitation Based on the cumulative anomaly and Mann-Kendall methods. The results show that the temperature in the Jiuquan basin as a whole is a certain upward trend with a slow decline between 1955-1985, then there have been a clear upward trend, while the precipitation don’t have apparent change trend with frequent and large fluctuations.
