石羊河流域气候变化及对作物生育期的影响
Characteristics of climate change and its influence on growth period of crops in Shiyang River basin
摘要
Abstract
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 .关键词
