摘要： 为了研究石河子地区冻土分布的时空演变规律及其影响冻土的主要气象因子，通过对石河子地区4个气象台站冻土气象观测资料的整理和分析。结果表明：在全球变暖背景下，近50年来各站最大冻土深度逐渐减少，但减少的程度不一致，其中莫索湾站减少明显，石河子站次之，炮台站、乌兰乌苏站变化不明显。石河子的冻结始日最早，莫索湾地区最晚；炮台解冻最晚，莫索湾站最早；冻土持续时间炮台站、石河子站、乌兰乌苏逐渐减少，莫索湾站逐渐增加。影响冻土变化的主要影响因子是冬季平均气温和最大积雪深度。

Abstract: In order to analyze the spatial and temporal distribution and impact of meteorological factors of frozen soil, the author used the frozen soil observational data of 4 meteorological stations in Shihezi Region. The results showed: in the context of global warming, nearly all stations gradually reduced the maximum depth of frozen soil, but the extent of reduce was inconsistency, which was Mosuowan station reduced significantly, Shihezi Station followed it, Paotai and Wulanwusu Station changed obvious in the recent 50 years, Shihezi freeze start date was the earliest, Mosuowan most late; Paotai thaw latest, Mosuowan earliest; the duration of frozen soil, except Mosuowan gradually increased, the other station gradually reduced. The average winter temperature and maximum snow depth were the major factors affecting of frozen soil.
