摘要： 为了研究潍坊深层地温对气候变化的响应，利用潍坊市1980—2014年0.8~3.2 m地温资料，运用线性倾向估计、Mann-Kendall和滑动t检验等统计方法，对潍坊市近35年深层地温的变化特征进行分析。结果表明：0.8~3.2 m地温变化趋势不显著，均未发生突变，一年中，仅夏季各深层地温呈增温趋势。年代际变化上，1980s和2010s各层平均地温均高于1990s和2000s。深层地温在冬季随深度增加，稳定性渐好，夏季反之，一年中，稳定性最好和最差分别发生在夏季和冬季0.8 m地温层。气温对深层地温的影响明显，季、年平均气温与同期各深层地温多呈正相关，随着深度的增加，气温与各层地温的相关性略有降低，这是深层地温变化存在滞后性所致，降水量对各深层地温影响不大。

Abstract: Weifang 0.8-3.2 m earth temperature data from 1980 to 2014 was utilized, linear tendency estimation, Mann-Kendall and sliding t test statistical methods were used for analyzing the change features of deep-seated earth temperature in Weifang in recent 35 years in order to study the response of deep-seated earth temperature to the climate change in Weifang. The result showed that the change trend of 0.8-3.2 m deep-seated earth temperature was not obvious and had no mutation. All deep-seated earth temperatures showed an increase trend only in summer throughout the year. Average earth temperatures at all levels in 1980s and 2010s were higher than that in 1990s and 2000s in the aspect of interdecadal change. Deep-seated earth temperature increased with depth in winter and had better stability, which was contrary to that in summer. The best and worst stability occurred respectively in 0.8 m earth temperature layer in summer and winter. Temperature had prominent influence on deep-seated earth temperature. Quarterly average temperature and annual average temperature were positively correlated to all deep-seated earth temperatures over the same period. The correlation between temperature and all deep-seated earth temperatures was slightly decreased with depth increase because changes of deep-seated earth temperature were lagged. Precipitation had slight influence on all deep-seated earth temperatures.
