摘要： 利用塔城地区6个气象站1961—2016年的逐日气温数据,采用气候倾向率、累积距平法、Mann-Kendall突变检验法和ArcGIS空间插值法,对该区≥10 ℃积温的时空变化特征进行分析。结果显示:研究区≥10 ℃初终日、持续日数和积温分别以-0.12 d·(10a)-1、0.15 d·(10a)-1、0.27 d·(10a)-1、75.39 ℃·(10a)-1的倾向率呈提前、推迟、延长、增多的趋势,其中≥10 ℃终日、持续日数和积温均发生突变;≥10 ℃积温分布主要集中于2 450~3 950 ℃,研究区南部≥10 ℃积温较北部高;阶段Ⅱ(1995—2016年)和阶段Ⅰ(1961—1994年)相比,各地≥10 ℃积温均有所增加,并且2 450~3 150 ℃的区域面积占总面积的比例有明显的减少趋势,3 150~3 450 ℃、3 450~3 950 ℃、3 950~4 150 ℃和4 150~4 250 ℃占的区域面积占总面积的比例均有所增长,其中3 150~3 450 ℃所占面积比增长最明显。

Abstract: In this paper, the spatiotemporal variation of the accumulated value of temperature ≥10 ℃ in Tacheng was analyzed using the methods of linear climate tendency, cumulative anomalies, Mann-kendall mutation test and ArcGIS space interpolation based on the daily average temperature data from 6 meteorological stations in Tacheng during the period from 1961 to 2016. The results showed that the first date, last date, duration and accumulated value of temperature ≥10 ℃ in the study area were changed by -0.12 d·(10a)-1, 0.15 d·(10a)-1, 0.27 d·(10a)-1 and 75.39 ℃·(10a)-1 respectively. Moreover, the mutations of the last date, duration and accumulated value of temperature ≥10 ℃ occurred. The accumulated value of temperature ≥10 ℃ in the study area varied in a range from 2 450 ℃ to 3 950 ℃, and it was higher in the south than that in the north. Compared with the period Ⅱ (1995-2016) and period Ⅰ (1961-1994), the accumulated value of temperature ≥10 ℃ increased to some extent, the proportion of the area with accumulated value (2 450-3 150 ℃) of temperature ≥10 ℃ was reduced obviously, but the proportions of the areas with accumulated values of 3 150-3 450 ℃, 3 950-4 150 ℃ and 4 150-4 250 ℃ were increased.
