摘要:

为揭示寿光市地表温度的演变规律和变化特征,采用线性回归分析和累积距平等现代气候学诊断统计方法,对寿光市1961—2017年0 cm地温的变化趋势及其与气温、日照、降水量和水汽压等气象要素的相关性进行分析。结果表明:寿光市年、季平均地温及平均最高地温、平均最低地温均呈升高趋势,最低地温的增温幅度最明显,达0.54℃/10 a;年平均地气温差呈极显著递减趋势,平均每10年递减0.16℃;通过分析发现寿光地温大约在20世纪90年代初期经历了一场由冷到暖的突变。地温的季节性增幅差异较大,冬、春季地温的升高和最低地温的显著增温是引起寿光地温升高的原因之一,降水量和日照的减少,水汽压的降低是导致当地地温变化的重要气象因素。

Abstract:

To reveal the surface temperature evolution rules and characteristics of Shouguang City, the paper used modern climatology diagnostic and statistical methods as linear regression analysis and cumulative anomaly to analyze the variation trend of surface temperature from 1961 to 2017. And the relationship between surface temperature and air temperature, sunshine duration, precipitation, water vapor pressure and other meteorological elements was also discussed. The results showed that in Shouguang City, the annual and seasonal mean surface temperature, the average maximum surface temperature and the average minimum surface temperature all showed an increase trend, and the minimum surface temperature increased most obviously with 0.54℃/10 a. The difference between annual mean surface temperature and air temperature decreased significantly at the rate of 0.16℃/10 a. It was found that the surface temperature in Shouguang City experienced a sudden change from cold to warm in the early 1990s. The seasonal increase of surface temperature varied greatly. And the rise of the surface temperature in winter and spring and the significant increase of the lowest surface temperature were the reasons for the rise of the city surface temperature, in addition, the decrease of precipitation and sunshine duration and the decline of water vapor pressure were important meteorological factors leading to the change of local surface temperature.
