摘要: 在气候变暖背景下,研究临汾市0℃界限温度的变化特征,以期为农业生产提供科学依据。利用临汾市17个地面气象站1981—2014年逐日气温资料,采用线性倾向估计法、滑动平均法、M-K法及距平,对临汾市日平均气温稳定通过0℃的初日、终日、持续日数及积温的时空分布特征进行分析。结果表明:临汾市日平均气温≥0℃初日提前,终日延迟,持续天数呈增加趋势,增长速率为3.9天/10年,初日的提前程度大于终日的延迟程度,临汾市≥0℃的活动积温总体呈增加趋势,增长速率为115.4℃/10年,1993年为突变增长年,2000年之后上升趋势显著性增强;从地域分布看,中部平川地区出现≥0℃初日最早,结束最晚,持续期最长,≥0℃的活动积温最充足,而西山出现≥0℃初日最晚,结束最早,持续期最短,≥0℃的活动积温最少,东山介于平川和西山之间。对于气候变暖给农业生产带来的影响必须进行综合深入的研究。

Abstract: Under the background of climate warming, it studied the changing characteristics of 0℃ boundary temperature of Linfen, in order to provide scientific basis for agricultural production. Based on the daily air temperature data of 17 meteorological stations from 1981 to 2014, by using the linear trend estimation method, moving average method, the M- K method, and anomaly, several elements were analyzed, including the beginning day, ending day, duration and accumulated temperature of the daily temperature above 0℃ stably. The results showed that the beginning day was in advanced, the ending day delayed, the duration was increased 3.9 days per decade, the ahead of beginning date was greater than the ending date delay, and the accumulated temperature of the daily temperature above 0℃ stably had an increasing trend, which increased 115.4℃ per decade in Linfen, mutation in 1993, increasing significantly enhanced after 2000; from regional distribution, central regions above 0℃ began earliest, ended latest, duration longest, the accumulated temperature above 0℃ was most abundant, the west mountain was conversely, the east mountain was between the two. The impact of climate warming to the agricultural production must be comprehensive researched.
