利用1961—2014 年武威市凉州区气象观测资料,笔者采用数理统计方法系统分析了冬季气温、降水、日照时数的气候变化特征。结果表明:冬季气温持续性升高,其倾向率为0.617℃/10 a,且通过99%显著性水平检验;冬季降水量倾向率为0.107 mm/10 a,日照时数倾向率为-1.6721 h/10 a,但二者均未通过显著性水平检验。在冬季气候变暖的背景下,日光温室生产将面临多重影响,笔者以此提出了一些应对措施,这些措施将为研究区域日光温室丰产增收提供参考依据。
Abstract
Employing the meteorological observation data from 1961 to 2010 of the meteorological station in Liangzhou District, Wuwei City, and using the mathematical statistics method, the climate change characteristics were analyzed systematically including the temperature, precipitation and sunshine hours in winter. The results showed that: the temperature in winter significantly increased, and the climate tendency rate was 0.617℃/10 a, which passed the significance level test of 99%; the precipitation in winter increased slightly, and the climate tendency rate was 0.107 mm/10 a; sunshine hours had a slight decrease tendency, and the climate tendency rate was -1.6721 h/10 a. The climate tendency coefficient of precipitation and sunshine hours did not pass the significance level test. Under the background of climate warming in winter, solar greenhouse would face multiple impacts, so a series of countermeasures were proposed to deal with climate change in winter, which would provide a scientific basis for high yield and bumper harvest.
