根据1958-2004年江汉平原地区8个站点的月平均气温资料,采用一元回归、相关分析和距平等数理统计方法对近47 a江汉平原地区的多年年、月平均气温和各站点年平均气温随时间的变化进行分析.结果表明:近47 a江汉平原地区年平均气温呈明显上升趋势,四季气温特别是秋、冬季的气温上升显著,而夏季有变凉趋势;月平均气温除7月呈下降趋势之外,其余各月均上升;太阳黑子峰值年和谷值年前后,江汉平原地区的年平均气温易出现极值.

Based on monthly average temperature data in 8 stations of Jianghan plain from 1958 to 2004, the changes of annual and monthly average air temperatures in Jianghan plain and annual average air temperature in each station were analyzed with linear regression analysis and correlation analysis as well as statistical analysis. The results showed that the annual average temperature increased obviously in Jianghan plain during the past 47 years, especially air temperatures in autumn and winter, while it decreased in summer. The monthly average air temperature was an ascending trend, except in July. ...
