利用石河子地区1961～2007年的积温实时资料,分析了石河子地区积温的空间分布、年代际、年际变化特征以及积温日数和各级积温初终日变化。结果表明,47年来石河子地区积温及积温日数总体呈逐年增加趋势,随积温界限值的提高,积温增加幅度减小,但积温及积温日数的年际变幅大,各级积温及积温日数在47年里发生了突变。
Based on the real-time accumulated temperature data in Shihezi area from 1961 to 2007, the spatial distribution, interannual and interannual variability of accumulated temperature in Shihezi area and the diurnal variations of accumulated temperature days and accumulated temperatures at different levels were analyzed. The results show that the accumulated temperature and accumulated temperature days have been increasing year by year in the past 47 years. With the increase of the accumulated temperature limit, the increasing range of accumulated temperature decreases, but the interannual amplitude of accumulated temperature and accumulated temperature day is large, A mutation occurred during the year.
