摘　　要：基于石河子市1955—2020年逐日平均气温观测数据,分析了近66年石河子冬季负积温变化特征,为合理利用冬季气候资源提供参考。结果表明:石河子冬季负积温总体呈减少趋势,气候倾向率为-31.7℃·d/10a,累积距平1987年出现了突变,≤0℃初日推迟,终日提前和持续日数减少,冷冬年份均出现在2000年之前,而暖冬在20世纪80年代到21世纪00年代间出现频次较多。Based on the observation data of daily mean temperature in Shihezi city from 1955 to 2020, the characteristics of negative accumulated temperature in winter in shihezi city in recent 66 years were investigated,which could provide reference for rational use of winter climate resources. The results show that the negative accumulated temperature in winter in Shihezi presents a decreasing trend,and the climate trend rate is-31.7℃·d/10 a.The cumulative anomaly has a sudden change in 1987, with the onset of the day delayed, the length of the day advanced and the duration of the day decreased. The cold winter years all occurred before 2000, while the warm winter occurred more frequently from 1980 s to 2000 s.
