摘要:

根据乌鲁木齐气象台1961 ~ 2009 年的气温、降水及0. 8 m、1. 6 m、3. 2 m 地温资料,对地温变化特征及其对气候变化的响应进行了分析和探讨。结果表明: 乌鲁木齐深层平均地温在1985 年之后的年际和季节变化均呈现升高趋势,四季变化中冬季地温升高最为显著; 深层地温和气温的变化相关性达到了0. 679 以上,说明气温的变化还是影响深层地温变化的主要因素之一; 降水对深层地温有一定的影响。

关键词: 深层地温, 乌鲁木齐, 气温, 降水, 响应

Abstract:

 Based on air temperature,precipitation and ground temperature at the depth of 0. 8 m,1. 6 m and 3. 2 m provided by Urumqi Meteorological Observatory from 1961 to 2009,the variation of ground temperature and its response to climate change are analyzed and discussed. The results show that the inter - annual and seasonal variation of the average ground temperature at each depth presented a rising trend after 1985 in Urumqi,and ground temperature increasing in winter was most significant. The correlation between ground temperature at each depth and air temperature was more than 0. 679,which showed that the change of air temperature was the main factor leading to ground temperature change; Precipitation has a certain impact on the deep ground temperature.

Key words: deep ground temperature, Urumqi, air temperature, precipitation
