中文摘要:
      〗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3～5 a，降雨量1～3 a。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。
英文摘要:
      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 s tatistical 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 decreased) 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.
