利用石羊河流域5个农业气象观测站1951-2009年气象资料和武威市作物（春小麦、玉米）生育期观测资料，采用线性对比分析、Mann-Kendall趋势检验和突变检验分析、Arcgis空间统计分析、Morlet小波分析、SPSS统计分析等方法，分析了该地区的气候变化特征，以及气候变化对作物（春小麦、玉米）生育期的影响。结果表明：近60年来石羊河流域不同地区的气温呈不同程度的上升趋势，月、季、年平均降水增量不同程度地增（减），并且气候变化显著周期分别为：平均气温3～5a，降雨量1～3a。从气象因素对作物生育期的影响可以看出，降水是影响春小麦乳熟期长短的主要气象因素，而气温和降水与玉米关键生育期的相关性不显著。

To gain insight into the characteristics of climatic change and its influence on the growth period of crops (spring wheat and corn ) in the Shiyang River basin ,the meteorological data of five agricultural meteorological stations during 1951-2009 and the growth period observation data of crops in Wuwei City were analyzed using linear contrast analysis ,Mann-Kendall trend test and mutation test analysis ,Arcgis spatial statistical analysis ,Morlet wavelet analysis , and SPSS statistical analysis .The results showed that there was an increasing tendency of temperature in different areas of Shiyang River basin in last 60 years , while the monthly , quarterly and annual mean precipitation increased (or de-creased ) to different extents .The significant change periods of mean temperature and precipitation were 3~5 a ,and 1~3 a , respectively . Precipitation was the main meteorological factor that impacted the length of milky stage of spring wheat ,however ,there was no significant correlation between temperature (precipitation ) and key growth periods of corn .
