摘　　要：利用新疆输油气管道沿线14个气候观测站1971—2010年逐日14时160 cm地温观测数据、日平均气温和日最低气温数据资料,分别采用均值法和线性倾向估计法分析了输油气管线160 cm地温的时空分布特征和地温的变化趋势,同时还分析了新疆输油气管道沿线160 cm地温与气温的变化关系。结果表明:输油气管道沿线160 cm地温总体呈北低南高的态势,近30 a南北疆管线地温均上升了1℃左右,有所不同的是,大气的升温幅度较160 cm地温升温明显,且地温变化滞后于气温变化,二者之间无显著的相关关系。冬季管线160 cm最低地温出现时间南北疆略有差异,南疆大部分在2月中旬出现,北疆则在2月下旬至3月上旬出现。In this paper, we used 160 cm ground temperature data, the average daily temperature and daily minimum temperature data during 1971-2010 from 14 climate observation stations along Xinjiang^s oil and gas pipelines. It was analyzed that the Spatiotemporal distribution and trends of ground temperature with the mean method and linear trend, and also the relationship between the 160 cm ground temperature and air temperature. Through the analysis, the results showed 160 cm ground temperature along the pipelines was lower in north and higher in south, and the ground temperature rose by about 1 ~C in the north and the south of Xinjiang in recent 30 years. The difference was that the warming of the atmosphere temperature was obviously compared with 160 cm ground temperature, and the ground temperature change lagged behind the atmosphere temperature change, also, there was no significant correlation between the two temperatures. The change rate of the ground temperature in North Xinjiang was greater than that in South Xinjiang. The minimum ground temperature appeared slightly different in time between South Xinjiang and North Xinjiang in winter, most of the minimum ground temperatures in south Xinjiang are in the mid-February while those in north Xinjiang occurs from late February to early March.
