| 摘 要： | 为了揭示寿光市冬季负积温的变化规律,合理利用气候资源,本研究基于寿光市1960—2018年逐日平均气温观测资料,统计负积温及最长持续日数,利用现代气候诊断分析方法,分析负积温及最长持续日数变化特征及产生影响,为寿光工农业生产提供参考依据。结果表明,（1）寿光市1961—2018年负积温总体呈减少趋势,气候倾向率为-32.8℃/10 a。冬季各月负积温变化趋势均呈减少趋势,1月对冬季变暖贡献最大。负积温在1989年发生了突变;（2）冬季负积温最长持续日数总体呈减少趋势,气候倾向率为-5.0 d/10 a。负积温最长持续日数初日年代平均值推迟了12天。21世纪初10年,冬季寒冷开始晚,结束的早,较历年平均值缩短了18天;（3）负积温变化对农业影响利弊并存;（4）负积温对工业影响利大于弊。

| Abstract: | The paper aims to reveal the variation regularity of negative accumulated temperature in winter in Shouguang, and make rational use of climate resources. Based on the daily mean temperature observation data of Shouguang from 1960 to 2018, the paper counted the negative accumulated temperature and the maximum duration of days, and analyzed the variation characteristic of them and their effects by using the method of modern climate diagnostic analysis, so as to provide a basis for industrial and agricultural production in Shouguang. The results showed that: (1) the negative accumulated temperature showed a decreasing trend from 1961 to 2018 in Shouguang with the climate tendency rate of -32.8℃/10 a; the variation of negative accumulated temperature in winter showed a decreasing trend, and January contributed the most to winter warming; the negative accumulated temperature had a mutation in 1989; (2) the maximum duration of days of negative accumulated temperature in winter showed a decreasing trend in Shouguang with the climatic tendency rate of -5.0 d/10 a; the mean first day of the maximum duration of negative accumulated temperature was delayed by 12 days; in 2010s, the winter cold began late and ended early, showing 18 days shorter than the average of previous years; (3) negative accumulated temperature variation had both advantages and disadvantages on agriculture; (4) negative accumulated temperature had more advantages than disadvantages on industry. |
