摘要: 选取了河西走廊西部的酒泉市绿洲区为代表,利用境内8个气象站1961—2018年的逐日气温实测数据,主要采用五日滑动平均、气候倾向率、M–K突变检验和小波分析等方法,分析了近60年典型绿洲生态区≥10 ℃积温的时空变化特征。结果表明,≥10 ℃积温区域分布不均,差异较大;≥10 ℃积温呈现出初日提前、终日推迟为主的增加趋势;近60年≥10 ℃积温、终日和持续日数分别在2004、1974和1997年发生了突变;≥10 ℃积温存在准26年强振荡周期,在1961—1970年、1971—1999年以及21世纪以来大致呈现了升高-降低-升高的变化过程;≥10 ℃积温初日、终日和持续日数的短周期振荡在各时段有较明显的差异性。

Abstract: Jiuquan oasis in the west of Hexi Corridor is selected as the representative. Based on the daily temperature data of 8 meteorological stations in Jiuquan city from 1961 to 2018, the temporal and spatial variation characteristics of accumulated temperature greater than or equal to 10 ℃ in typical oasis eco-region in recent 60 years was analyzed by using 5-day moving average, climate tendency rate, M-K mutation test method and wavelet analysis. The results are as follows: The accumulated temperature greater than or equal to 10 ℃ is unevenly distributed, and the regional distribution is quite different. The accumulated temperature greater than or equal to 10 ℃ shows an increasing trend in which the first day is ahead of schedule and the final day is delayed. In recent 60 years, the accumulated temperature greater than or equal to 10 ℃, the final day and the duration days was changed abruptly in 2004, 1974 and 1997, respectively. The accumulated temperature greater than or equal to 10 ℃ has a strong oscillation period of quasi-26 years, since 1961—1970, 1971—1999 and 21st century, the change process of rise-fall-rise has been generally presented; The short-period oscillation of the first day, the final day and duration days of the accumulated temperature greater than or equal to 10 ℃ are obviously different at each time interval.

Key words: typical oasis eco-region, accumulated temperature, climate evolution, wavelet analysis, regional response
